Hi everyone,
Sunday fun :)
One of our critical Linux VMs ran out of disk space. I cleared up space
by removing old application logs within the guest, rebooted the guest
and was presented with the following information message during bootup
when the filesystem ext3/4 scan runs:
/Clearing orhpaned inode ...../
Shortly after this message the the guest is paused by oVirt and the "VM
has paused due to unknown storage error" message is displayed in the
oVirt web GUI.
On the physical node itself, I found the following error
in/var/log/vdsm/vdsm.log:
/libvirtEventLoop::INFO::2012-12-02
09:05:50,296::libvirtvm::1965::vm.Vm::(_onAbnormalStop)
vmId=`23b9212c-1e25-4003-aa18-b1e819bf6bb1`::abnormal vm stop device
ide0-0-1 error eother/
Any ideas on how to get more informationon what exactly the error is?
I've tried booting the guest into rescue mode, run a manual fsck on the
logical volume but each time the guest is automaticall paused due to the
"unknown storage error".
We are using a FC SAN for storage, sowhat I've decided to try is export
the disk using "dd" on the physical node and then try repairing it by
mounting it as a loop filesystem on another physical server, and then
use "dd" to import it back in again.
Is this the right approach to take to get the system back online?
