Dear All, Does someone had seen that error ? When I run this command from my virtual machine: # time dd if=/dev/zero of=enrico.dd bs=4k count=10000000 VM was paused due to kind a storage error/problem. Strange message because tell about "no storage space error" but ovirt puts virtual machine in a paused state. Inside events from ovirt web interface I see this: "VM has been paused due to lack of storage space" but no ERROR found in /var/log/vdsm.log. My oVirt enviroment 4.2.1 has three hypervivosr with FC storage and before now I haven't see any other problem during the normal functioning of the vm , it's seem that this error occurs only when there is massive I/O. Any ideas ? Thanks a lot.
