Which hard disk, printer, UPS, network camera and backup software are compatible with NAS?

Please check out the compatibility lists, which you can find at http://support.ts.fujitsu.com. ▲Back

Hard disk error is shown. What can I do?

1. The message “disk drive x failed or is unplugged” is shown in Event Log. 2. The message “disk drive x failed or is unplugged” is shown on the LCD

panel. 3. Abnormal disk message shown in hard disk configuration under

administrator mode, e.g. “no disk”. Note: Please inform your customers that some data may not be recovered due to different status of disk damage.

Solution: 1. RAID 1 and RAID 5 configuration: Turn off the system and replace the

damaged disk(s). NAS will perform disk recovery when the system restarts. The system can run properly and all data can be used again. Note: It is recommended to replace the damaged disk with new one of the same model.

2. Single disk volume: Turn off the system and replace the damaged disk after the system restarts. When the NAS restarts, launch the web browser, e.g. IE 6/7, and login the system. Go to Disk Configuration page to configure the disk volume. Note that only the data on other three disks can be reserved.

3. JBOD and RAID 0: Turn off the system and replace the damaged disk. When the NAS restarts, launch the web browser, e.g. IE 6/7, and login the system. Go to Disk Configuration page to configure the disk volume. Note that the data on the damaged disk cannot be recovered.

Maintenance steps. 1. Unfasten the screws on the disk tray. 2. Take out the disk tray. 3. Check if any disk is damaged. (Unplug the possible damaged disk and

insert to other machine for examination.) 4. Replace the damaged disk. 5. Make sure the new disk is of the same model as the other three. 6. Check the master and slave settings of the disks. Disk checking after maintenance: 1. Turn on the server. 2. Make sure no disk error message is shown on the LCD panel. 3. Login the system as administrator. 4. Check the disk status in disk volume configuration page. If the message

“Not initialized” is shown, the disk is installed successfully. 5. When the disk volume is configured as RAID 1, the system will rebuild

upon successful restart. Make sure the system works properly and no errors are displayed after rebuilding.

Can I upgrade the memory of my NAS?

No, this will void the warranty of your NAS. Besides, the memory of some models is soldered to the main board. Thus, it’s not possible to replace or insert new memory to the NAS. ▲Back

Can I connect my PC's USB/eSATA port to NAS via USB or eSATA cable to access the DATA?

No, the USB / eSATA port on the NAS can only be connected to peripheral device. You can only connect to the NAS through the Ethernet network. ▲Back

What is the definition of HDD SMART status, Abnormal, Normal & Good?

Abnormal Normal Good 1. Any SMART value is equal or less than threshold. 2. Hard Disk temperature is higher than 65 degree C.

1. Any Smart value is equal or less than threshold + (initial_SMART_value - threhold)/2. For example, if the initial SMART value is 100, the current value is 50, the threshold is 20, then the Smart value, 50, is less than 20+(100-20)/2. Thus, the health level would be Normal. 2. Any SMART test (Rapid or Complete) result of last 20 times is abnormal. 3. Hard Disk temperature is between 55 to 65 degree C.

None of the conditions listed on the left side.

My NAS lost all its settings, and all HDDs are shown as unmounted.

In case of corrupt/lost config: 1. Power off the NAS and remove the HDD(s) 2. Power on the NAS 3. After a short beep and a long beep, plug the HDD back into the NAS 4. Run Fujitsu Finder, it will find the NAS, do NOT configure it! 5. Connect to the NAS by telnet port 13131 (e.g. with Putty) 6. Run the following commands to recover with default configuration Use the following commands if using 1 drive: # mount /dev/sda1 /mnt # cd /mnt/.config/ # cp /etc/default_config/uLinux.conf /mnt/.config/ # reboot

Use the following command if using 2 drives: # mdadm -A /dev/md9 /dev/sda1 /dev/sdb1 # mount /dev/md9 /mnt # cd /mnt/.config/ # cp /etc/default_config/uLinux.conf /mnt/.config/ # reboot

7. Above procedure will reset the configuration back to default and then you

need to reconfigure it. But all the share should be available now. Please remember NOT to re-initialize the HDD. Since this will format your HDD and all your data will be lost.

8. To be prepared next time this happens, always make sure you have a working backup of your personal uLinux.conf.

Note: uLinux.conf is the main settings configuration

▲Back

Is there a newer firmware available for the NAS Device? Do I need to install that?

Check the Fujitsu support page. If you see an available firmware you may need to download it and install it. Please verify first which version you have and then compare the release date.

To check which version you have, go to the WebUI of your NAS Device, the firmware version of your NAS is shown on bottom left.

▲Back

How to start the Fujitsu Finder to reinitialize the CELVIN® NAS Server?

Please remove your hard drives. Boot up the NAS without HDD installed. The system will use the embedded image to boot up. Then run the Fujitsu Finder on your PC, it will help you to find the NAS on the network.

Use the default username and password to login. Hot-plug the HDD into the NAS, and go thru the installation process including formatting hard disk & install the firmware.

▲Back

The Fujitsu Finder / Quick Install Wizard cannot find the NAS Device during the discovery process.

Windows XP SP1 with Internet Firewall enabled will not allow the Fujitsu Finder to find the NAS Device during the discovery process. The Internet Firewall must be momentarily disabled for the Quick Install Wizard to find the NAS Device properly. Once the Shortcut icons are created on the Desktop, the Internet Firewall settings can be re-enabled.

In Windows XP SP2 the Internet Firewall does not need to be disabled. However, a popup message will appear when running the Quick Install Wizard. Agree to the popup message to continue with the detection process.

▲Back


VERSION: 2.1


I have installed and followed all the instructions, but I cannot run the setup for the NAS Device.

You may need to RESET the device and then run the Quick Install Wizard / Fujitsu Finder again. For the best result, make sure you wait until the NAS Device is fully booted.

When you see that the POWER LED and the LAN LED are both ON, and not blinking, then the NAS Device has completed its boot up process.

▲Back

Do I lose all my data after I performed the system reset?

The Reset function on "System Administration > System Reset" is designed to reset all settings of the NAS to default. When you press Reset on this page, all drive data, user accounts, network shares and system settings are cleared and restored to default.

Please make sure you have backed up all the important data and system settings before resetting the NAS.

▲Back

Initialization stops during first time installation. What can I do?

If your NAS and PC are connected to the same router, enable DHCP on NAS and you should be able to access the server. To set a fixed IP for NAS, make sure the subnet mask, default gateway, and the DNS server settings of your NAS and PC are the same.

If you connect the NAS directly or there is no DHCP server on the network, the NAS will use 169.254.100.100 as its IP address. Please configure your PC to the same IP subnet, for example, 169.254.100.101.

▲Back

Why is the disk size of the NAS reduced after RAID configuration is finished?

When configuring two disks as RAID 1, the disk size usable is equal to the size of one disk. Hard disk manufacturer calculates disk size as 1M=1000K while computer calculates actual disk capacity as 1M=1024K.

When a manufacturer marks a disk size as 160G (disk size: 160G=160,000M=160,000,000K), the actual usable disk capacity could be 160,000,000,000K/1024/1024 = 152 G.

▲Back

What's the limitation on the length of server name?

The server name can be 14 characters long at maximum, which can contain alphabetic characters, numbers and hyphen (-).

The server does not accept names with space, period (.), or names in pure numbers.

▲Back

What's the limitation of the username and password setting?

User name The user name must not exceed 32 characters. It is case-insensitive and can contain double-byte characters, such as Chinese, Japanese, and Korean except: " / \ [ ] : ; | = , + * ? < > ` '

Password The password is case-sensitive and can be 16 characters long at maximum. It is recommended to use a password of at least 6 characters.

▲Back

Can I use Unicode character in password?

No, for password, only English alphabets and numbers are supported. You can use Unicode characters for user name only. ▲Back


VERSION: 2.1

HDD SPIN DOWN (HDD STANDBY)

Why does the hard drive of the NAS not go to standby mode?

First of all, make sure you have enabled the "disk standby mode" function in System Tools / Hardware Settings on the administration page. If the function does not work according to your settings, you may check if the following services are running. There must NOT be any access to these services for the HDD standby mode to work properly:

UPnP/Twonkymedia function on NAS NTP server BT download Microsoft Networking -> AD service, WINS server, Domain Master Share folder mapping

Network access to the NAS. If the NAS is connecting to Internet, make sure you don’t enable DMZ or port forwarding on your router/firewall. Hacker may try to connect your NAS and thus prevent HDDs to entering standby. Fujitsu Finder, Quick Install Wizard, NetBak Replication, QGet. These programs will keep checking the existence of the NAS and prevent it to entering standby.

If your NAS is shared among multiple PC on the same network, be sure there is no access from the PC to the NAS. You can disconnect the LAN cable to assure this. If you have installed add-on programs like Joomla or phpMyAdmin on your NAS, the HDD standby mode of CELVIN® NAS Server might not work since these programs might affect the service access status to the NAS. If you have copied a lot of pictures to the NAS, the NAS will create thumbnail files for the pictures. This may take a long time (even days if there is great number of pictures). You can see a running process “/usr/local/sbin/ImR_all -soft /Qmultimedia” after issue ps command via SSH. Please wait patiently for this process to complete. If you still have problem, please connect the NAS by ssh port 22 or telnet port 13131 and issue ps command. This will show all the running procedures.

▲Back

Why does my HDD go to standby mode later than the time I have set?

The hard drive(s) on CELVIN® NAS Server may seem to go to standby mode a bit later than the time you specified when data writing is in process. In fact, this is related to the data writing behavior of the embedded Linux system. When you save data to the NAS, the data is written to the system cache first and then

to the hard drive(s) on the NAS. The write time depends on the size of the data. After the data is written and there is no access to the hard drive, the hard drive(s) go to standby mode according to your settings in System Tools / Hardware Settings on the administration page.

▲Back

Can the HDDs remain in spin-down to conserve energy when just accessing the admin page?

Since the configuration and log files are stored on the HDD, any access or change to the NAS will wake up the NAS from standby mode.

▲Back


VERSION: 2.1


RAID

I have e.g. 2*250GB drives in RAID 1. In case drive fails, is it possible that I remove one 250GB drive and replace it with a 500GB drives?

Yes. However, the array capacity is based on the size of smaller drive. You could not have the 500GB RAID 1 until you back up the data to your PC or an external drive first, and then use 2*500GB drives for a new RAID 1

configuration. After the new RAID1 is configured, please copy the data back to your NAS

▲Back

What should be done when disk error is detected for RAID 1/5/6 configuration?

Take out the failed drive and replace it with a proper one of the same model or same/bigger size. To replace the failed disk with a different volume one, make sure the new disk is larger in size than the old one for rebuilding RAID

configuration. However, only the size of the old drive will be used for the new one. Extra size of the new drive will not be used.

▲Back

I’m using RAID 1 with my CELVIN® NAS Server Q800, but the performance does not meet the expectations.

In order to get best performance in RAID1 setup with CELVIN® NAS Server Q800, it is recommended to use HDD slot 1 and 3 or HDD slot 2 and 4 for installing the two hard drives.

When using HDD slot 1 and 2 or HDD slot 3 and 4 for your RAID 1, there may be a write performance decrease of ~30%.

▲Back

If the internal disk of CELVIN® NAS Server Q600 fails or the mainboard is changed when Q-RAID1 configuration is enabled, can I replace the internal disk with an eSATA or USB disk?

Yes. The internal disk can be replaced by the external disk. You can also install a new internal disk and execute “Restore” function to restore the data from the eSATA or USB disk to the new internal disk. ▲Back

The RAID migration / expansion speed is very slow, is this normal?

The first half of the RAID migration / expansion will take much longer than the second half. The second 50% will take just a few hours to complete. Thus, the RAID migration / expansion should be completed about half of time than you estimate from the progress percentage.

Our RAID migration / expansion is on-line. You can still use the NAS to read/write data as usual.

▲Back

Can I have two or more RAID volumes on my NAS? For example, RAID 1 for HDD slot 1&2, RAID 0 for HDD slot 3&4.

Yes, you can have two or more RAID volumes if the drive numbers support it. However, please refer to “I’m using RAID 1 with my CELVIN® NAS Server Q800 , but the performance does not meet the expectations.” to ensure the best possible read/write performance.

▲Back


VERSION: 2.1


I’ve already created two RAID 1 (or RAID 0) volumes. Can I create a RAID 0 (or RAID 1) over these two RAIDs?

No, you can only create raid over hard disks (1-level). Creating RAID over another RAID (2-level) is not supported. That means RAID01 and RAID10 are not supported on our NAS (yet). ▲Back


VERSION: 2.1


PRINTER SERVER

Why can’t I find the network printer?

Please do not create a folder with a name identical to the printer name otherwise you will not find the printer. ▲Back

How do I change the name of the printer connected to the NAS?

The printer name is named according to the name of NAS. To change the printer name, change the server name of the NAS and restart the server.

The printer name will be changed but the end of the name will still be "pr" or "pr2" "pr3". For example, the name of NAS is “nas”, then the printer name will be naspr.

REMOTE REPLICATION / DISASTER RECOVERY

Can I use remote replication to back up data to PC or NAS of different brands?

You can back up the data to PC or NAS with standard Rsync server installed. ▲Back

How to synchronize all data between two NAS devices?

Setup Remote Replication function, and enable "Perform incremental replication" function, "Delete extra files on remote destination" function. ▲Back

Why are files not completely backed up by the remote replication of the NAS?

This may due to corruption of files or file name settings. If the files are not damaged, you can check the language settings of the source and destination NAS servers. Make sure their language settings are the same. CELVIN® NAS

Server will skip backing up the files when errors are found and cannot be fixed during replication.

▲Back

Why does remote replication from NAS to external USB disk fails when the USB/eSATA disk is in FAT format?

This is a limitation of FAT file system. Some special characters are not supported by FAT file system, including / ? \:<>*|"

If the name of the source file contains any of these characters, remote replication will fail.

▲Back

I want to backup my data through the Internet. If I setup the NAS behind a firewall, and enable the Remote Replication function, which port I should open on the firewall rule?

The port used is 873 by default and is configurable. ▲Back

What should be done to make CELVIN® NAS Server back up the folders on the server automatically via self remote replication?

Set the remote server IP as 127.0.0.1 to make the NAS back up the data on itself. For example, there are two network shares A and B.

To make CELVIN® NAS Server backup data on A to B automatically, set remote CELVIN® NAS Server IP as 127.0.0.1 and remote folder as B, the data will then be backed up from A to B.

▲Back

My company often schedules backup job in non-office hours, how can I check the backup result when out of office?

All current statistics and past records are recorded in Statistics and Logs section.

▲Back


VERSION: 2.1


If the NAS device abnormally shutdown, the Remote Replication function will continue?

If remote destination NAS power off, network failure or other abnormal situation happened, the Remote Replication function will stop, and it will start on the next schedule.

Note: Please enable "Perform incremental replication" function, and then system will backup new files only, or it will backup from the beginning.

▲Back

I configured a weekly remote replication job but got an error.

This error is caused by the case-sensitiveness of the folder name for remote replication.

The remote host testing cannot identify the case of the folder name, e.g. Music and music. Please enter the correct folder name (case-sensitive) and try again.

▲Back

Why does remote replication not start after a long while when file compression option is enabled?

When file compression option is selected for remote replication, files will be compressed first before backup. Therefore, more time will be taken before replication starts. ▲Back

Why can the remote server not be connected after clicking on the test button in remote replication?

After pressing the test button, you have to enter the password again to use remote replication ▲Back

FTP SERVER

I use the NAS Device as a FTP server, but the users that are outside the LAN cannot access to it.

To use the NAS Device as a FTP server without fixed IP or domain name, please setup your DynDNS (if IP is not fixed) and Port Mapping of router (IP Sharing) first. As for the setting, please refer to the DynDNS and Port mapping in your router’s Manual.

We recommend to use a fixed IP address on the NAS Device and then configure your Router. Depending on the brand you use, you need to access the following:

Firewall > Virtual Servers Virtual Server Port Forwarding / Port Triggering Advanced Routing

▲Back

I tried to access some files on NAS via FTP by Internet Explorer but the file names are displayed incorrectly and I could not access the files. Why?

This is a limitation of Internet Explorer. When you access the files on an FTP server via IE, IE retrieves the information of the files, e.g. owner of the file, the user group that the owner belongs to, and last modified etc.

However, when the there is a space in the user group name, e.g. Power Users, IE recognizes the first word as the user group name and the word after the space as the value for the next variable. Therefore, the file names are displayed incorrectly (Figure 1).

Figure 1 To view the files correctly, you can use FTP clients, like File Zilla, or Mozilla Firefox (Figure 2) to access the FTP site. You can also modify the user group name and delete the space characters in the name.

If the user group belongs to your Windows server, you can go to Control Panel / Administrative Tools / Computer Management to change the group name (Figure 3). Note that you must have the administrator rights to change the group name.

▲Back

Why can't I see the correct filename using my FTP client?

Your FTP client does not support Unicode. Set "No" for Unicode Support from [FTP Service] under [Networking Settings]. Select a supported filename encoding from [Language Setting] under [System Settings] so that the folders and files on FTP can be properly shown.

Or you can just use the proper FTP client which supports unicode, such as "SmartFTP", "FileZilla" or "FTPRush".

▲Back


VERSION: 2.1


How to determine which language to be set for FTP?

If you need to connect to CELVIN® NAS Server via FTP, please follow the steps below to configure the language setting: 1. In “System Settings - Language Setting” page, select the language that

most users use. 2. If your FTP client does not support Unicode, e.g. Internet Explorer,

CuteFTP, WSFTP or Command-Prompt FTP, go to Network Settings-FTP Service page and disable Unicode support.

3. If your FTP client supports Unicode, e.g. FileZilla, enable Unicode support in the client. Then go to Network Settings-FTP Service page and enable Unicode support. Check if the files can be properly displayed in Internet Explorer.

Can users in different network domains configure the same NAS as network disk drive?

Yes. To access NAS by computer name, make sure there is WINS server in your network and the service is enabled. If not, you can access the server via NAS IP. ▲Back

Why are all files tagged as hidden system files?

You can fix this with the following procedure: 1. Make sure that system files were shown. 2. Copy all the folders, using a windows explorer, to the XP machine. You

may want to do this to a folder directly in C: (for example "c:\iamlost"). 3. Open a Command window --> (Start/run, and type "cmd", press enter) 4. Cd to the directory where you copied the files to (example: cd c:\iamlost) 5. Next we have to get rid of all the attributes;

type "attrib -R -A -S -H /S /D"

What you just did in step 5 is; you removed the file AND folder attributes -R (readonly), -A(archive), -S (system file,.. this is the one that's probably been bugging you), -H(hidden). The /S and /D are there to make sure you also process all sub-files and sub-folders. You should be able to make any changes to rights and visibilities again using the "normal" windows methods now.

▲Back

Why can the file name of a file with more than 33 characters not be displayed completely in the Internet Explorer browser? Is this a bug?

No. The problem that a file name cannot be displayed in the IE browser completely is not related to the length of the file name.

The file name is cut off because the display space of the IE status bar is limited and the total length of the path exceeds the buffer of the status bar.

Why can’t I log in with a user? I already gave the user RW or RO access right. (Why can I write into a share? I only gave the user RO access right.)

The answers to the above two questions are the same; the access right priority. Deny > RW > RO > Empty (no setting). Example 1: “UserA” is a member of “UserGroup”. If you give “UserA” RW or RO access right to “Public” share folder and at the same time you give “UserGroup” Deny to “Public”, per the access rule above, resulting access right for “UserA” is Deny. Example 2: “UserB” is a member of “UserGroup”. If you give “UserB” RO access right to “Qmultimedia” share folder and at the same time you give “UserGroup” RW access right to “Qmultimedia” share folder, per the access rule above, resulting access right for “UserB” is RW.

Example 3: “UserC” is a member of “UserGroupA” and “UserGroupB”. For share folder “Qdownload” you give “UserGroupA” RW, “UserGroupB” RO, and you do not configure “UserC” (Empty), the resulting access right for “UserC” is RW. Note: All users are in group “everyone” by default, please check your “everyone” access right for conflicts.

WINDOWS ACTIVE DIRECTORY SERVICE

How do I access the user account and group data from AD Domain?

It is suggested to use Windows 2000 Service Pack 4 or Windows 2003 Service Pack 1. Check your AD server settings: 1. Make sure you have enabled Active Directory Service on the Windows

server. If you have enabled AD, you can find the menu “Active Directory Users and Computers” on “Administrative Tools” of Windows.

2. Reset the password of “administrator” account on AD server after creating “Active Directory” service on AD server.

3. The DNS server settings on the AD server should have at least two records. For example, you have an AD server with IP address 10.8.10.113, server name: celvinsbs.tsdsbs.local, domain name: tsdsbs.local DNS settings on AD server: a. “A record” for AD server itself: celvinsbs Host(A) 10.8.10.113 b. “A record” for domain: (same as parent folder) Host(A) 10.8.10.113

How to create “A record” for domain on DNS settings: i. On “dnsmgmt”, select New Host(A) in Action. ii. Enter IP address: 10.8.10.113 (AD server IP address),

and then click “Add Host”. 4. The DNS IP on “Network setting” of AD server should have a record of

the AD server IP. Check the following items on NAS: a. DNS server setting on NAS should be directed to AD server. b. Check the “time zone” and “Current date and time” on NAS, AD

server can synchronize only if their time difference is less than 5 minutes.

5. You should use the full domain name in AD settings of NAS. For example, if your FQDN name of AD server is “celvinsbs.tsdsbs.local”, you should use “tsdsbs.local” as the domain name. Domain Username must be entered for AD domain. (We use “administrator” in this case).

6. NAS and AD server will synchronize each 5 minutes. To configure the settings manually, NAS has to be set as standalone mode and then added to AD domain again. If you cannot join AD domain, please switch to “Standalone” setting. Check all the settings and join AD again.

Notes: On joining AD 1. After joining NAS to AD domain, you must login the share folder of NAS

by “domain_name\Username”. NAS local user account cannot be used anymore on network sharing. For example: peter is an account on the AD domain (tsdsbs.local)

2. AD can be joined successfully even if NAS and AD server are on different subnets.

3. After NAS has joined AD domain, the authority of “everyone” will not work, “everyone” is the original account of NAS, but is not included in AD. Therefore the authority has to be reset.

4. DNS settings on Windows 2000 server should be added as “Active Directory DNS”.

5. If you change the DNS setting on the Windows server, please reboot the server to avoid DNS cache error.

▲Back

When adding NAS to AD, will the access authority of Windows be copied to NAS?

No. Access authority set in Windows will not be copied to NAS. You should set the access right on NAS. ▲Back

When adding CELVIN® NAS Server to Active Directory domain, will it inherit file read/write rights of Windows?

No, CELVIN® NAS Server is not able to inherit the access right from Windows. The access right will remain the same per original setting on CELVIN® NAS Server. ▲Back

How does the CELVIN® NAS Server encrypt the built-in Hard-drives? How do I unlock them?

The enhanced encryption technology uses AES-256 to encrypt disk volumes. The 8-16 character long, user-created passphrase and the generated key file via Web UI will create the encrypted disk volume based on the Linux LUKS mechanism. When the NAS reboots each time and before data can be

accessed, the encrypted disk volume must be mounted via the input of the passphrase or the key file on the Web Management UI. On the other hand, users can also choose to store the key file in the NAS for automatic unlock upon each reboot, without the manual input each time.

If I add a Virtual Disk to my NAS, can the volume capacity be merged to this volume?

Why does WinRAR show file names as unrecognized characters and fail to decompress after compressing the files with Web File Manager?

This is because Web File Manager uses UTF-8 encoding for compression. WinRAR v3.92 and earlier versions cannot fully support UTF-8 encoded files. Please use WinZip as an alternative solution for decompression. ▲Back
