Example -- Creating a Trans Metadevice With a Stripe for the Master Device

# umount /home2
# metainit d40 -t d2 c1t2d0s0
d40: Trans is setup
(Edit the /etc/vfstab file so that the file system references the trans metadevice)
# mount /home2

Stripe d2 contains a file system mounted on /home2. The slice to contain the logging device is /dev/dsk/c1t2d0s0. First, the file system is unmounted. The metainit command with the -t option creates the trans metadevice, d40.

Next, the /etc/vfstab file must be edited to change the entry for the file system to reference the trans metadevice. For example, the following line:

/dev/md/dsk/d2 /dev/md/rdsk/d2 /home2 ufs 2 yes -

should be changed to:

/dev/md/dsk/d40 /dev/md/rdsk/d40 /home2 ufs 2 yes -

Logging becomes effective for the file system when it is remounted.

On subsequent reboots, instead of checking the file system, fsck(1M) displays a logging message for the metadevice:

# reboot
...
/dev/md/rdsk/d40: is logging
