VM was paused due to kind a storage error/problem. Strange message<br>
because tell about "no storage space error" but ovirt puts virtual machine in<br>
a paused state.<br>
<br>
Inside events from ovirt web interface I see this:<br>
<br>
"VM has been paused due to lack of storage space"<br>
<br>
but no ERROR found in /var/log/vdsm.log.<br>
<br>
My oVirt enviroment 4.2.1 has three hypervivosr with FC storage and before now<br>
I haven't see any other problem during the normal functioning of the vm , it's seem<br>
that this error occurs only when there is massive I/O.<br>
<br>
Any ideas ?<br>
Thanks a lot.<br>
Best Regards<br>
Enrico<br>
