[Linux-cluster] Processes locked in "D" state

[Brynnen R Owen]

Hi all,

  While my initial problems with getting the locking/fencing seem to
be solved with the proper magma modules, my initial problem is not
solved.  I have been running some test backups to a GFS partition
which somehow has a bad directory on it.  Here's what I mean.  Any
process that tries to open this "bad" directory gets hung forever in a
"D" state.  There are no errors/warnings/logs anywhere.  I have tried
'ls <path>', 'find .' on a directory above this bad one in the path,
'/gfs_tool stat <path>', and the original perl script which was
descending into directories and copying stuff.  I now have 4 hung
processes.  The machine still appears awake.  'df' still works (this
is an improvement over the old failure method).  Any suggestions? 

I'm using lock_dlm
gfs from CVS on Nov 11. which I applied to a kernel.org 2.6.9 kernel.
Using mptscsih fibre channel cards.
Athlon processors with athlon extensions
No extra high memory (1G limit)
Non-SMP
base system is RedHat 9.
