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><u></u><u></u></p></div></div></div><p class="MsoNormal"><br clear="all"><u></u><u></u></p><div><p class="MsoNormal"><u></u> <u></u></p></div><p class="MsoNormal">-- <u></u><u></u></p><div><div><p class="MsoNormal">Tiemen Ruiten<br>Systems Engineer<br>R&D Media<u></u><u></u></p></div></div></div></div></div></div></div></blockquote></div><br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr">Tiemen Ruiten<br>Systems Engineer<br>R&D Media<br></div></div>
