(URGENT!!) Disks have disappeared from the SAN
Hi all,
Has anyone experienced SAN backed disks just disappearing?
Yesterday I created about 40 small VMs whose disks were backed by a SAN. Everything was fine until I apt-get update ; apt-get dist-upgrade this morning and then rebooted.
Now some of the VMs won't start and pvesm list --all shows an absence of their disks. Other VMs are fine. I cannot find any pattern to the missing ones either.
Background: cluster of two identical machines each with 2x1GB connections to the SAN. I created the SAN storage (marked shared but not one LVM per machine) on the master and then created an LVM group (marked shared) for the entire size of the SAN storage. I then created the VMs - nothing different between the broken and working ones.
The cluster is running 1.5 - 6.2.18
One very *very* bizarre thing is that the master can ping the SAN however the client node (which has the broken VMs) cannot. Even though it cannot ping the SAN it can still start up some of the VMs with SAN backed disks....
I previously used ESXi on this SAN and have had no problems.
Help would be gratefully received - this is very critical for me.
