Configure screen logging through SSH

We recommend that you configure screen logging to log all session input and output during your troubleshooting session. This log file can be shared with Isilon Technical Support, if you require assistance at any point during troubleshooting.

Note: The screen session capability does not work in OneFS 7.1.0.6 and 7.1.1.2. If you are running either of these versions, you can configure logging by using your local SSH client's logging feature.

1. Open an SSH connection to the cluster and log in by using the root account.

Note: If the cluster is in compliance mode, use the compadmin account to log in. All compadmin commands must be preceded by the sudo prefix.

2. Change the directory to / i f s/ dat a/ I si l on_Suppor t by running the following command:

cd / i f s/ dat a/ I si l on_Suppor t

3. Run the following command to capture all input and output from the session:

scr een - L

This will create a file named scr eenl og. 0 that will be appended to during your session.

4. Perform troubleshooting.

Before you begin

CAUTION!If the node, subnet, or pool that you are working on goes down during the course of troubleshooting and you do not have any other way to connect to the cluster, you could experience data unavailability.

Therefore, make sure that you have more than one way to connect to the cluster before you start this troubleshooting process. The best method is to have a serial console connection available. This way, if you are unable to connect through the network, you will still be able to connect to the cluster physically.

For specific requirements and instructions for making a physical connection to the cluster, see article 304071 on the EMC Online Support site.

Before you begin troubleshooting, confirm that you can connect through either another subnet or pool, or that you have physical access to the cluster.

"Permission denied" errors

Page 14



Check for permission denied errors by running the following command:

gr ep ' Per mi ssi on deni ed' / var / l og/ webui _webwar e. l og

The output will look similar to the following:

2019- 1- 26T15: 53: 44- 08: 00 <18. 3> cl ust er - 1( i d1) ht t pd[ 1000] : [ er r or ] [ cl i ent 192. 168. 100. 1] ( 13) Per mi ssi on deni ed: access t o / st yl e/ ext 1/ ext - al l . css deni ed, r ef er er : _ht t ps: / / cl ust er - 1. l ocal : 8080/ St at us?l oadSt at e=1

Check to see if the Apache processes across all nodes are being run by the local daemon user (UID = 1), by running the following command:

ps auxwwwHl | egr ep " ^daemon| USER"

See Appendix D for example output and more information.

Is the UID value for each PID

listed as 1?Go to Page 15Yes

Refer to the following KB article to determine if there are duplicate local user accounts that need to be removed:

No

Did the KB article resolve the

issue?End troubleshooting



No Yes

- Page 14 - "Permission denied" errors

Check the Apache directory ownership by running the following command:

f i nd / usr / l ocal / www - not - user 0 - and - not - user 1 - exec l s - l and { } \ ;

If no output is returned, the directory is owned by "daemon" and this is correct.

Did the command return

any output?No

Yes

Correct the permissions by running the following command for your version of OneFS, where <v#> is the value of v1 or v1 from the output of the previous command:

OneFS 8.1chown - R 1: 1 / usr / l ocal / www/ st at i c/ <v#>

OneFS 7.2 - 8.0.xchown - R 1: 1 / usr / l ocal / www/ st at i c/ ui / *

Were you able

to log in?

End troubleshooting



Appendix A.

Yes No

End troubleshooting

Can you log in as root?

Try to establish an SSH connection to any node

in the cluster.No

Check to see whether you have any external authentication providers enabled (LDAP, Legacy LDAP, Active Directory, or NIS) by following the

directions for your version of OneFS:

OneFS 8.xUnder the Access menu, select Authentication

Providers. Under the Active Directory, LDAP and NIS tabs, look to see if each provider has a green dot. This green dot indicates that the external provider is

online.

OneFS 7.2Click Cluster Management > Access Management.

In the Access Zones tab, look to see if Active Directory, LDAP, or NIS has a green dot. A green dot

indicates that external provider is enabled.

If you need to contact Isilon Technical Support during troubleshooting, reference the page or step that you need help with. This information and the log file will help Isilon Technical Support staff resolve your case more quickly.

Appendix A: If you need further assistance

Upload node log files and the screen log file to Isilon Technical Support

1. When troubleshooting is complete, in the command-line interface, type exi t to end your screen session.

2. Gather and upload the node log set and include the SSH screen log file by using the command appropriate for your method of uploading files. If you are not sure which method to use, use FTP.
