Removing of mirror disk doesn't require reboot.

It's simple. 1st identify how many LVs you have in mirrored.

lvextend -m 0

Verify that you have successfully removed the mirror

lvdisplay -v

remove disk from VG

vgreduce

Remove disk from the system

ioscan -fnk |grep disk |awk '{print $3}'

rmsf -H

Shibin,

>> lvextend -m 0

mirror_copies can have the value 1 or 2. It must be greater than the current value.

You have to lvreduce.
