Subject: [ovirt-users] ERROR 'no free file handlers in pool' while creating VM from template<br>
<br>
Hello,<br>
<br>
I ran into a nasty problem today when creating a new, cloned VM from a template (one virtual 20 GBdisk) on our two-node oVirt cluster: on the node where I started a VM creation job, load skyrocketed and some VMs stopped responding until and after the job failed. 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>
