PING : REPLACING AN LVM DISK : STEP 2.3
|
Reactivate the volume group so that the new disk can be attached, since it wasn't configured in at boot time. This will also resync any mirrors that resided on the faulty disk.
# vgchange -a y
For our example, the volume group vg00 will already be
activated, but it
will not know of the replaced disk. Therefore, this step is still
required
so that LVM will now know that the disk is again available and the
resync
will occur:
# vgchange -a y /dev/vg00
