Description Christopher Hicks 2001-06-23 04:35:38 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.72 [en] (X11; U; Linux 2.2.13 i686)

Description of problem:
During shutdown it gets to "Sending all processes the KILL signal..."
Then there are some messages from the raid system:
	raid5d(122) flushing signals.
	md: recovery thread got woken up ...
	md: recovery thread finished ....
	mdrecoveryd(8) flushing signals.
	md_do_sync() got signal ....exiting
	raid5: resync aborted!

When it gets down to Unmounting file systems it hangs.  I presume this is
because the raid daemon is dead by then.  The filesystem on the RAID is
reiserfs, so it's not that big a deal to hit reset and let the box come
back up.  But it's annoying that it hangs and it does take a minute for the
ext2 file systems (/ and /boot) to clean themselves up.

How reproducible:
Didn't try

Steps to Reproduce:
I don't have any other systems with RAID drives so I can't say that I've
reproduced it.  But it does do it

Expected Results:  I would have expected the box to shutdown cleanly.

Additional info:

I've installed all the updates after doing a clean install on this box.

I had RH6.2 and an ext2 filesystem on a RAID in this system before without
any trouble.

Comment 3 Elliot Lee 2001-09-20 23:50:30 UTC
Hangs usually only happen when unmounting NFS file systems - just sit and wait
for things to happen.

Sorry, that's about the only explanation I can think of besides slow hardware,
which you probably would have already factored in.
