Hi,

I'm trying to configure Red Hat GFS but have problems starting CLVMD on
the second node of a 3-nodes cluster. I can start ccsd, cman, and fenced
successfully, and clvmd on any other nodes first time.

-------------------------
CenOS 4.4
Kernel: 2.6.9-42.0.3.ELsmp
[root at server2 ~]# cman_tool nodes
Node  Votes Exp Sts  Name
   1    1    3   M   server3
   2    1    3   M   server4
   3    1    3   M   server2

-------------------------
First Node (able to start clvmd successfully)

[root at server3 ~]# cman_tool  services
Service          Name                              GID LID State
Code
Fence Domain:    "default"                           1   2 run       -
[1 2 3]

DLM Lock Space:  "clvmd"                             2   3 update
U-4,1,3
[1 3]

[root at server3 ~]# cat /proc/cluster/dlm_debug
clvmd move flags 0,1,0 ids 0,3,0
clvmd move use event 3
clvmd recover event 3 (first)
clvmd add nodes
clvmd total nodes 1
clvmd rebuild resource directory
clvmd rebuilt 0 resources
clvmd recover event 3 done
clvmd move flags 0,0,1 ids 0,3,3
clvmd process held requests
clvmd processed 0 requests
clvmd recover event 3 finished
clvmd move flags 1,0,0 ids 3,3,3
clvmd move flags 0,1,0 ids 3,4,3
clvmd move use event 4
clvmd recover event 4
clvmd add node 3

--------------------------
Second Node (forever waiting)

[root at server2 ~]# cman_tool services
Service          Name                              GID LID State
Code
Fence Domain:    "default"                           1   2 run       -
[1 2 3]

DLM Lock Space:  "clvmd"                             2   3 join
S-6,20,2
[1 3]

[root at server2 ~]# cat /proc/cluster/dlm_debug
clvmd move flags 0,1,0 ids 0,2,0
clvmd move use event 2
clvmd recover event 2 (first)
clvmd add nodes
--------------------------

Any ideas why?

Thanks in advance,
