Hi,
I had VG's and LV's on top of a Linux MD RAID1 array using two iSCSI
volumes. Apparently this RAID1 array wasn't started properly after a
reboot, so LVM detected two duplcate PV's (both RAID1 members had the
same PV UUID) and chose to use one of them. Unfortunately I didn't
notice it so it ran like that for a while.
I was lucky and the machine was only rebooted once, so LVM used the same
PV all the time, but what would happen on a next reboot?
How does LVM decide which one to use? Will it always choose the same one?
Thanks, Danilo
