Review the following considerations when mounting file systems:
Similar to Oracle Solaris 10 releases, a ZFS file system is mounted automatically when it is created. No need exists to edit the /etc/vfstab to mount local ZFS file systems.
If you want to create and mount a local legacy UFS file system to be mounted at boot time, you will need to add an entry to the /etc/vfstab file as in previous Oracle Solaris releases.
If you want to mount a remote file system at boot time, you will need to add an entry to the /etc/vfstab file and start the following service:
# svcadm enable svc:/network/nfs/client:default
Otherwise, the file system is not mounted at boot time.
