Comment 1 lars@bistromatic.de 2010-05-14 19:43:35 UTC

Still see this bug with F13RC3.

Comment 2 lars@bistromatic.de 2010-05-29 11:24:32 UTC

Still see this bug using F13.
The error message changed a little bit:

Starting mdmon:  /etc/rc.d/init.d/functions: line 526:  1625 Segmentation fault      "$@"    	[FAILED]

Comment 3 Doug Ledford 2010-07-20 22:55:37 UTC

This should be fixed now.

Comment 6 lars@bistromatic.de 2010-07-24 12:14:32 UTC

I still get this bug.
Although, now I see it only in one of three or four reboots. It's still there.

During every reboot I get this message during udev start:

Starting udev: udevd-work[738]: '/sbin/mdadm -I /dev/sdc' unexpected exit with status 0x000b

In 50% it's sdc otherwise it's sdd. Both discs are used by an ICH9R fake raid for an NTFS volume. I don't use that volume under fedora, so it's not mounted during boot.

Comment 13 lars@bistromatic.de 2010-08-12 19:15:48 UTC

Still get the segmentation fault using mdadm-3.1.3-0.git20100804.2.fc13.x86_64.

Comment 14 Tristan Santore 2010-09-18 12:24:39 UTC

Yes, I also see the same problem here. I also tried the updates-testing version, and it still segfaults.

This is quite annoying, as I only now realised that my array was degraded!

I was relying on mdmonitor to dump stuff in the logs!

The priority on this is wrong! It should be high!

Comment 15 lars@bistromatic.de 2010-10-17 19:16:28 UTC

Still get the segmentation fault using current Fedora 14 beta.
