Remove mirror disk

[j773303]

As title, in VG00, /home has
been mirror to another disk,
how to remove the mirror disk
from /home?

Hi,

This should do it. Change the '?' to the corresponding lvol number you have, or change the 'lvol?' to the corresponding logical volume name for /home

# lvreduce -m 0 /dev/vg00/lvol?

You'll have to umount /home before reducing. And if you can't from run level 3 then you'll have to use LVM maintenance mode.

umount /home
fuser /home (* to see what processes are attached to /home *)
lvreduce -m 0 /dev/vg00/lvol4

LVM maintenance mode is tricky, try this first and respond if you need it.
