The Virtual File System Table

Most file systems are mounted automatically by an SMF service at system boot time.

You might need to edit the /etc/vfstab file to mount legacy or remote file systems or to make changes to the ZFS swap volume. For information about changing a ZFS swap volume, see Chapter 3, Configuring Additional Swap Space.

    To add an entry for mounting a legacy or remote file system, the information you need to specify is as follows:

  • The device or the NFS server where the file system resides

  • The file system mount point

  • File system type

  • Whether you want the file system to mount automatically when the system boots (by using the mountall command)

  • Any mount options

The following vfstab example is from a system that has a ZFS root file system. In addition, this system is mounting a remote file system, /users/data, from the NFS server, neo.

# cat /etc/vfstab
#device         device          mount           FS      fsck    mount   mount
#to mount       to fsck         point           type    pass    at boot options
fd              -               /dev/fd         fd      -       no      -
/proc           -               /proc           proc    -       no      -
/dev/zvol/dsk/rpool/swap -      -               swap    -       no      -
/devices        -              /devices         devfs   -       no      -
sharefs         -              /etc/dfs/sharetabsharefs -       no      -
ctfs            -              /system/contract ctfs    -       no      -
objfs           -              /system/object   objfs   -       no      -
swap            -              /tmp             tmpfs   -       yes     -
neo:/users/data	 -          /data            nfs     -       yes     -

ZFS file systems are mounted automatically by the SMF service at boot time. You can mount ZFS file systems from the vfstab by using the legacy mount feature.
