Everything recovered without intervention, but this obviously shouldn't happen. I have attached the relevant vdsm log file. The button to create the VM was pressed around 11:17, the first error in the vdsm log is at 11:23:58.<br><br>The ISO domain is a gluster volume exposed via NFS, the storage domain for the VM's is also a gluster volume. The underlying filesystem is ZFS.<br>The hypervisor nodes are full CentOS 6 installs.<br><br>I'm guessing the 'no free file handlers in pool' in the vdsm log file is key here. What can I do to prevent this from happening again? Apart from not creating new VMs of course :)<br><br>Tiemen<br><br><o:p></o:p></p></div></div></div><p class=MsoNormal><br clear=all><o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal>-- <o:p></o:p></p><div><div><p class=MsoNormal>Tiemen Ruiten<br>Systems Engineer<br>R&D Media<o:p></o:p></p></div></div></div></div></body></html>
