Subject: [ovirt-users] ERROR 'no free file handlers in pool' while =
creating VM from template
Hello,
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.
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.
The hypervisor nodes are full CentOS 6 installs.
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 :)
