Turn on the XFS tracing so we can see what is being written every 36s. When the problem shows up: # echo 1 > /sys/kernel/debug/tracing/events/xfs/enable # sleep 100 # cat /sys/kernel/debug/tracing/trace > trace.out # echo 0 > /sys/kernel/debug/tracing/events/xfs/enable And post the trace.out file for us to look at.
