[Linux-cluster] problem starting clvmd on second node.

[Dan Deshayes]

when i start the clvmd on the second node in debugmode it seems to start 
fine.

[root at asl012 conf.d]# clvmd -d
CLVMD[aaabc2c0]: Jun 20 15:06:13 CLVMD started
CLVMD[aaabc2c0]: Jun 20 15:06:22 Cluster ready, doing some more 
initialisation
CLVMD[aaabc2c0]: Jun 20 15:06:22 starting LVM thread
CLVMD[aaabc2c0]: Jun 20 15:06:22 clvmd ready for work
CLVMD[aaabc2c0]: Jun 20 15:06:22 Using timeout of 60 seconds
CLVMD[41401940]: Jun 20 15:06:22 LVM thread function started
File descriptor 5 left open
CLVMD[41401940]: Jun 20 15:06:23 LVM thread waiting for work

but when i try to mount it the proccess just freezes. /var/logs/messages:
Jun 20 15:06:22 asl012 clvmd: Cluster LVM daemon started - connected to CMAN
Jun 20 15:07:19 asl012 kernel: Trying to join cluster "lock_dlm", 
"acl002:project_db"
Jun 20 15:07:19 asl012 kernel: dlm: connecting to 2
Jun 20 15:07:19 asl012 kernel: Joined cluster. Now mounting FS...

and then nothing happens.
root     19031  0.0  0.0   3628   332 pts/0    D    15:07   0:00 
/sbin/mount.gfs /dev/projectVG/db /project/db/ -o rw
after trying to do this the filesystem locks up on the first node also.

the fenced is running and starts fine when starting the cman-service.
I'm not tryin to make the filesystem failover but to be mounted by all 
nodes always.
