Hi everyone,
Sunday fun :)
One of our critical Linux VMs ran out of disk space. I cleared up space=20
by removing old application logs within the guest, rebooted the guest=20
and was presented with the following information message during bootup=20
when the filesystem ext3/4 scan runs:
/Clearing orhpaned inode ...../
Shortly after this message the the guest is paused by oVirt and the "VM=20
has paused due to unknown storage error" message is displayed in the=20
oVirt web GUI.
On the physical node itself, I found the following error=20
in/var/log/vdsm/vdsm.log:
/libvirtEventLoop::INFO::2012-12-02=20
09:05:50,296::libvirtvm::1965::vm.Vm::(_onAbnormalStop)=20
vmId=3D`23b9212c-1e25-4003-aa18-b1e819bf6bb1`::abnormal vm stop device=20
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=20
logical volume but each time the guest is automaticall paused due to the=20
"unknown storage error".
We are using a FC SAN for storage, sowhat I've decided to try is export=20
the disk using "dd" on the physical node and then try repairing it by=20
mounting it as a loop filesystem on another physical server, and then=20
use "dd" to import it back in again.
Is this the right approach to take to get the system back online?

It seems that your guest file system is corrupted.
The dd approach won't help cause this is a virtual disk,
you need to fix the virtual disk inside the lv, that's why any operations on the lv
won't help.
You can try shutting down the vm (not paused, but literally down) and add the guest vm
disk as
a second disk to another vm.
In the second vm try to run fsck on the disk and see if it helps.
In any case before trying to manipulate the disk image please save a backup!!!
let me know how it goes...

On the physical node itself, I fo und t he following error in

I managed to get the guest running again byusing dd and qemu-img to=20

But if this is the case, I think this should be considered as a bug, correct?
The VM should start and give an error itself, such as stopping at
grub, error on pivot_root, panic, ecc...
without impact on its ability to power on itself...
or not?

I think we should be a bit more exact here: a VM without an installed OS
does not pause. The cause of the pause was, most probably, and attempt
to read from a corrupted qcow. When qemu fails to serve the guest with
data due to a bug in the underlying storage, qemu stops and waits for
further instructions from management. We use this feature for automatic
lv-extend (on enospace error). But here, with eother error, a human
intervension is required.

Hi everyone,
Thank you for your responses.
Yeela:
/>When oVirt started the vm it mounted the corrupt disk image that=20
seemed fine, but it couldn't find the OS because of the corrupted fs,=20
and the error caused it to pause the guest./
To clear things up it was the /var mount that had the corrupted=20
filesystem, not the guest's root filesystem.
oVirt still continued to pause the guest even when I had booted the=20
guest off a CentOS DVD ISO, run rescue mode and manually activated the=20
/var logical volume. In this case I did not activate or mount the guests=20
root filesystem and only activated the guests /var filesystem so that I=20
could fsck it. fsck would run for around 5-10 minutes with the message=20
"Deleting orphaned inode......" and then oVirt would simply pause the=20
entire guest.
The only information I could find was on the physical host's vdsm.log,=20
which specified the following:
/libvirtEventLoop::INFO::2012-12-02=20
09:05:50,296::libvirtvm::1965::vm.Vm::(_onAbnormalStop)=20
vmId=3D`23b9212c-1e25-4003-aa18-b1e819bf6bb1`::abnormal vm stop device=20
ide0-0-1 error eother
/Perhaps there was another log I should have examined to see if more=20
information was provided about why oVirt was pausing the guest?
//
Shu:
This is what I did to dd the images off, and to work around the problem:
1.) On the physical host: Created an NFS mount to another temporary=20
Linux system that had sufficient storage for the 500GB filesystem
2.) On the physical host: Used 'dd' to dump the /var filesystem's=20
logical volume to an image filevia NFS on the temporary Linux system.
3.) On the temporary Linux system that now contained the filesystem=20
image file, I ran "qemu-img info" and noticed that thefilesystem image=20
was qcow2 type and specified a backing file.
4.) On the physical host: Used 'dd' to dump the logical volume specified=20
as a backing file, to an image file via NFS on the temporary Linux system.
5.) On the temporary Linux system: Used 'qemu-img rebase' to change the=20
backing file to the local copyof the backing file image.
6.) On the temporary Linux system: Used 'qemu-img commit' to commit the=20
changes stored in the filesystem image file to the backing file image.
7.) On the temporary Linux system: Used 'qemu-img convert' to convert=20
the backing file image to raw format.
8.) Onthe temporary Linux system: Used 'losetup', 'kpart'and
'fsck' to=20
repair the backing file image. Fsck displayed the same 'Deleting=20
orphaned inode....' message but managed to continue and completed ok.
9.) On the temporary Linux system: Mounted the loop filesystem and=20
confirmed that the data was intact and was current.
10.) In the oVirt GUI: Deactivated the faulty Virtual Disk attached to=20
the guest.
11.) In the oVirt GUI: Created a new 'preallocated' Virtual Disk of=20
sufficient sizefor the guest.
12.) On the physical host: Used 'dd' to upload the raw backing file=20
image from (7) to the new logical volume.
13.) I then configured the guest to boot from the CentOS DVD ISO into=20
rescue modeto confirm that the logical volume for the guest's /var=20
filesystem was accessible and mountable.
14.) Reconfigured the guest to bootfrom it's primary Virtual Disk and=20
started up the guest.

When oVirt started the vm it mounted the corrupt disk image that seemed fin=

but it couldn't find the OS because of the corrupted fs,
and the error caused it to pause the guest.
</pre </blockquote <pre wrap=3D"" I think
we should be a bit more exact here: a VM without an installed OS
does not pause. The cause of the pause was, most probably, and attempt
to read from a corrupted qcow. When qemu fails to serve the guest with
data due to a bug in the underlying storage, qemu stops and waits for
further instructions from management. We use this feature for automatic
lv-extend (on enospace error). But here, with eother error, a human
intervension is required.
