been mirror to another disk,
how to remove the mirror disk

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.
