hi,
wonder if you could try one more test for me.
With the other (echo BEFORE / echo AFTER etc) tracing still there, change the
/sbin/udevadm settle --timeout=$MDADM_DEVICE_TIMEOUT
to
/sbin/udevadm --debug settle --timeout=$MDADM_DEVICE_TIMEOUT > /dev/kmsg 2>&1
I found there is a case where "udevadm settle" can exit before the queue is
empty. It seems like a very unlikely scenario, but it seems clear that
something "unlikely" is happening.
I'm hoping to see
timeout waiting for udev queue
appear in the logs when this runs.
If you could add that and post the 'dmesg' output if you ever get that
message - or maybe even if you don't - that would be very helpful.
Thanks,
NeilBrown
