Re: [linux-lvm] vgscan problem



Andrew,

so you did pvcreate the second PV and added (vgextend) it to your existing
VG successfully?
What exactly happened before vgscan complained?

You should have a valid LVM metadata backup in /etc/lvmconf/big_space.conf
(or an older copy named /etc/lvmconf/big_space.conf.#.old where # is a number
from 1 up to 9).
To figure out which one is ok you want to for eg. use

vgcfgrestore -n big_space -f /etc/lvmconf/big_space.conf -ll


To restore the metadata run:

pvcreate -ff /dev/BothOfYourPVs
vgcfgrestore -n big_space -f /etc/lvmconf/big_space.conf /dev/Your1stPV
vgcfgrestore -n big_space -f /etc/lvmconf/big_space.conf /dev/Your2ndPV
vgscan
