Comment 6 Corey Marthaler 2007-04-04 11:43:39 EDT
I appear to have hit this same issue now without using a corelog. I had a disk
log with GFS on top, and the mirror was fully sync'ed so the down conversion
should have worked. Also, after I noticed the deadlock, a 'vgreduce
--removemissing helter_skelter' didn't cause the down convert to work, it only
hung as well. I'll need to reboot it appears to get out of this state.

cmirror-kernel-2.6.9-27.0

Comment 7 Jonathan Earl Brassow 2007-04-10 03:26:40 EDT
What is the deadlock timeout set to?

How much I/O is happening?

Are there clvmd timeouts happening?
Comment 8 Jonathan Earl Brassow 2007-04-16 16:44:23 EDT
I'm setting this one to modified, given all the changes since the last
reproduction.  Please attempt with cmirror-kernel >= 2.6.9-30.1

I don't think this was ever a problem in cmirror-kernel.  I think it's a problem
with clvmd timeouts.  If you can reproduce the problem, look for clvmd timeout
problems (should say something like "Error locking on node X: ... timeout").  If
you find those errors, then it is bug 235092 - otherwise, this bug is valid.

I have been unable to reproduce this bug with the latest version. Marking
verified in cmirror-kernel-2.6.9-32.0.

Fixed in current release (4.7).
