Description Mark Wu 2013-02-01 13:41:18 UTC
Description of problem:
Engine raises a warning that free space in /var/run/vdsm is less than 1G. But /var/run is mounted as a tmpfs. By default, the maximum size is half of the total physical memory. The warning is misleading because people could find it still have a lot of free space on the disk filesystem. And 1g shouldn't be a low threshold for memory.  So it seems we needn't monitor the usage of '/var/run/vdsm' in 'diskStats' since it could be covered by memory usage monitoring.

Version-Release number of selected component (if applicable):
vdsm-4.10.3-6.fc18.src.rpm

I think that this is better solved on the Engine side, by lowering the threshold for /var/run/vdsm. We would like to keep monitoring that that directory exists and has *some* free space (both for Fedora and EL6).

Dan, can you recommend the value to be changed please?

Comment 3 Dan Kenigsberg 2014-01-14 11:39:23 UTC
/var/run/vdsm contains tiny .pid files, smalle .recovery files, soft links, etc. I think that 100MiB would be enough for a big production server.
