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

# umount /home1
# metainit d63 -t c0t2d0s2 c2t2d0s1
d63: Trans is setup
(Edit the /etc/vfstab file so that the file system references the trans metadevice 
# umount /home1

Slice /dev/dsk/c0t2d0s2 contains a file system mounted on /home1. The slice to contain the logging device is /dev/dsk/c2t2d0s1. First, the file system is unmounted. The metainit command with the -t option creates the trans metadevice, d63.

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/dsk/c0t2d0s2 /dev/rdsk/c0t2d0s2 /home1 ufs 2 yes -

should be changed to:

/dev/md/dsk/d63 /dev/md/rdsk/d63 /home1 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 trans metadevice:

# reboot
...
/dev/md/rdsk/d63: is logging
