ZFS is the default file system when it comes to Solaris 11. In
solaris 11, Oracle made it
even easy to share ZFS as NFS file system. The major change that
oracle made in NFS
sharing is that it removed the dependency of /etc/dfs/dfstab to
share NFS permanently.
The file /etc/dfs/dfstab is obsolete in Solaris 11, so even if
you make any changes to it,
they are ignored.
Solaris 11 makes use of SMF services to share the NFS file
systems automatically while
booting. In solaris 11 the ZFS file system is shared as NFS in 2
steps :
Step 1
Name the share, by assigning a value to datasets name property
:# zfs set share=name=fs1,path=/fs1,prot=nfs geekpool/fs1
Publish the share by setting the sharenfs property to on
Step 2# zfs set sharenfs=on geekpool/fs1
There is no need to edit any file to make the share permanent.
By default when you turn
on the sharenfs property to on, it gets permanently shared. SMF
services takes care of
sharing the NFS file system while booting.The legacy ZFS sharing
Syntax (Solaris 10 Way)
The legacy way of sharing the ZFS file system as NFS (using
share command) from solaris
10 is still supported without having to use /etc/dfs/dfstab.
Instead we use the
file /etc/dfs/sharetab in Solaris 11.# share -F nfs /fs1# cat
/etc/dfs/sharetab/fs1 - nfs rw
Display the shares
To display the information on shared NFS file systems you can
use below 2 commands :# zfs get sharenfs geekpool/fs1NAME PROPERTY
VALUE SOURCEgeekpool/fs1 sharenfs on local
# zfs get share geekpool/fs1NAME PROPERTY VALUE
SOURCEgeekpool/fs1 share name=geekpool_fs1,path=/fs1,prot=nfs
local
Inheritance of share
When you share a ZFS file systems as NFS, all its children
inherit the sharenfs property.
For example if we share geekpool/fs1 :# zfs set
share=name=fs1,path=/fs1,prot=nfs
geekpool/fs1name=fs1,path=/fs1,prot=nfs
# zfs set sharenfs=on geekpool/fs1
If you check the share sharenfs property of geekpool/fs1/fs2
which is a child dataset of
fs1 :# zfs get sharenfs geekpool/fs1/fs2
