Re: [ovirt-users] Ovirt Hypervisor vdsm.Scheduler logs fill partition

Hello, I had a hypervisor semi-crash this week, 4 of ~10 VM's continued to run, but the others were killed off somehow and all VM's running on this host had '?' status in the ovirt UI. This appears to have been caused by vdsm logs filling up disk space on the logging partition. I've attached the log file vdsm.log.27.xz which shows this error: vdsm.Scheduler::DEBUG::2016-10-11 16:42:09,318::executor::216::Executor::(_discard) Worker discarded: <Worker name=periodic/3017 running <Operation action=<VmDispatcher operation=<class 'virt.periodic.DriveWatermarkMonitor'> at 0x7f8e90021210> at 0x7f8e90021250> discarded at 0x7f8dd123e850> which happens more and more frequently throughout the log. It was a bit difficult to understand what caused the failure, but the logs were getting really large, then being xz'd which compressed 11G+ into a few MB. Once this happened the disk space would be freed, and nagios wouldn't hit the 3rd check to throw a warning, until pretty much right at the crash. I was able to restart vdsmd to resolve the issue, but I still need to know why these logs started to stack up so I can avoid this issue in the future.
