[Linux-cluster] umount hung single node

[Daniel McNeil]

I upgraded to 2.6.11 and the latest cvs a few days ago.
I started my tests on Mar  7 16:01 and they hung on Mar  9 12:34.
This is a 3 node cluster, but the test that hung only has 1
node with gfs mounted and it is trying to unmount:

root     12500 12494  0 12:34 ?        00:00:01 umount /gfs_stripe5

$ cat /proc/12500/wchan
.text.lock.ast

dlm_astd is spinning as top shows:

12302 root      20  -5     0    0    0 R 99.9  0.0 280:28.23 dlm_astd

I've attached the output from /proc/cluster/dlm_debug.

Is there any other useful data to pull off the node to see what is
going on?

Daniel
