that "something" == bonnie ...

Also note the really low I/O .--- Bad Bonnie --- (multiple concurrent processes)filesrv2,136G,,,14389,16,10165,13,,,64722,9,134.3,0,16,212,2,+++++,+++,206,2,226,1,+++++,+++,177,2 semop: semop failed. : Resource temporarily unavailable
Is it unique to xfs? this is an error from bonnie's semop() call; it's not immediately clear that there is a problem with xfs. Is bonnie deadlocking? Is xfs stuck? echo w > /proc/sysrq-trigger to see if there are stuck processes and where they are. -Eric
