# metainit d0 -m d10
# metaroot d0
Use the metaroot d0 command only on the root slice.
5. Mirror the swap slice.
# metainit -f d11 1 1 c0t0d0s1
# metainit -f d21 1 1 c0t1d0s1
# metainit d1 -m d11
6. Mirror the var slice.
# metainit -f d14 1 1 c0t0d0s4
# metainit -f d24 1 1 c0t1d0s4
# metainit d4 -m d14
7. Mirror the usr slice.
# metainit -f d15 1 1 c0t0d0s5
# metainit -f d25 1 1 c0t1d0s5
# metainit d5 -m d15
8. Mirror the opt slice.
# metainit -f d16 1 1 c0t0d0s6
# metainit -f d26 1 1 c0t1d0s6
# metainit d6 -m d16
9. Mirror the home slice. Run metastat metadevice for information on a metadevice. If you want to
delete a metadevice, run metaclear metadevice.
# metainit -f d17 1 1 c0t0d0s7
# metainit -f d27 1 1 c0t1d0s7
# metainit d7 -m d17
10. Update /etc/vfstab to mount the mirrors after boot. The following is an example of
/etc/vfstab before changes:
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
#/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr ufs 1 yes -
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/dsk/c0t0d0s1 - - swap - no -
/dev/md/dsk/d30 /dev/md/rdsk/d30 / ufs 1 no logging
/dev/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /usr ufs 1 no ro,logging
/dev/dsk/c0t0d0s4 /dev/rdsk/c0t0d0s4 /var ufs 1 no nosuid,logging
/dev/dsk/c0t0d0s7 /dev/rdsk/c0t0d0s7 /home ufs 2 yes
nosuid,logging
/dev/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6 /opt ufs 2 yes nosuid,logging
swap - /tmp tmpfs - yes -
Make the following changes so that /etc/vfstab reads as follows:
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
#/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr ufs 1 yes -
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/md/dsk/d1 - - swap - no -
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no logging
/dev/md/dsk/d5 /dev/md/rdsk/d5 /usr ufs 1 no ro,logging
/dev/md/dsk/d4 /dev/md/rdsk/d4 /var ufs 1 no nosuid,logging
/dev/md/dsk/d7 /dev/md/rdsk/d7 /home ufs 2 yes nosuid,logging
