Hi Jan, > Doesn't look near the limit currently (but I suppose you rebooted it in the > meantime?).
the box this numbers came from has an uptime of 13 days so it's one of the boxes that did survive yesterdays half-cluster-wide-reboot. > Did iostat say anything about the drives? (btw dm-1 and dm-6 are what? Is > that your data drives?) - were they overloaded really? no they didn't have any load and or iops. Basically the whole box had nothing to do. If I understand the load correctly, this just reports threads that are ready and willing to work but - in this case - don't get any data to work with.
