<br>
<br>
were these 23 snapshots created any way each time we fail to create the snapshot or are these older snapshots which you actually created before the failure?<br>
<br>
at this point my main theory is that somewhere along the line you had some sort of failure in your storage and from that time each snapshot you create will fail.<br>
if the snapshots are created during the failure can you please delete the snapshots you do not need and try again?<br>
<br>
There should not be a limit on how many snapshots you can have since it's only a link changing the image the vm should boot from.<br>
Having said that, it's not ideal to have that many snapshots and can probably lead to unexpected results so I would not recommend having that many snapshots on a single vm :)<br>
<br>
for example, my second theory would be that because we have so many snapshots we have some sort of race where part of the createVolume command expects some result from a query run before the create itself and because there are so many snapshots there is "no such file" on the volume because it's too far up the list.<br>
<br>
can you also run: ls -l /rhev/data-center/9497ef2c-<u></u>8368-4c92-8d61-7f318a90748f/<u></u>95b9d922-4df7-4d3b-9bca-<u></u>467e2fd9d573/images/466d9ae9-<u></u>e46a-46f8-9f4b-964d8af0675b<br>
<br>
lets see what images are listed under that vm.<br>
<br>
btw, you know that your export domain is getting StorageDomainDoesNotExist in the vdsm log? is that domain in up state? can you try to deactivate the export domain?<br>
<br>
Thanks,<br>

Sorry for the confusion.<br>

I attempted to take a live snapshot of a running VM. After<br>
that failed, I migrated the VM to another host, and<br>
attempted<br>
the live snapshot again without success, eliminating a<br>
single<br>
host as the cause of failure.<br>
<br>
Ovirt is 3.3.4, storage domain is gluster 3.4.2.1, OS is<br>
CentOS 6.5.<br>

I made another live snapshot attempt at 10:21 EST<br>
today, full<br>

please explain the flow of what you are trying to<br>
do, are you<br>
trying to live migrate the disk (from one storage to<br>
another), are<br>
you trying to migrate the vm and after vm migration is<br>
finished<br>
you try to take a live snapshot of the vm? or are you<br>
trying to<br>
take a live snapshot of the vm during a vm<br>
migration from<br>
host1 to<br>
host2?<br>
<br>
Please attach full vdsm logs from any host you are<br>
using<br>
(if you<br>
are trying to migrate the vm from host1 to host2)<br>
+ please<br>
attach<br>
engine log.<br>
<br>
Also, what is the vdsm, libvirt and qemu versions,<br>
what ovirt<br>
version are you using and what is the storage you<br>
are using?<br>
<br>
Thanks,<br>
