RE: [Linux-cluster] CLVM



Hi,

I should probably provide the info from "cman_tool nodes" as well (in
addition to the info below) so that the info is clearer...

[root server2 ~]# cman_tool nodes
Node  Votes Exp Sts  Name
   1    1    3   M   server3 <- first node which started CLVMD
   3    1    3   M   server2

Regards,
Bernard

Hi,

Thanks for the quick reply. Here is the info that I gathered;

--------------------------------------------
Node 1 (which started CLVMD successfully):

[root 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

[root 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]

--------------------------------------------
Node 2 (which just wait forever):

[root 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

[root 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]
--------------------------------------------

Thanks for any help,
Bernard

Hi,

I have problems starting clvmd in a second node (after starting it
successfully on the first node) of a newly created 4-nodes cluster; no
problems staring the service first time on any nodes. Running "cman_tool
services" will show that the second node which started clvmd is in a
"join" status while the first node show a "update" status. This remains
even after a long period of time.

Given that the directories (i.e. /var /usr / ) are created using the
default lvm manager during installation, and I install the
lvm2-cluster-2.02.06-7.0.RHEL4.x86_64.rpm subsequently as part of the
requirements to set up GFS, will this cause the clvmd not to start
properly? I have no problems starting ccsd, cman and fenced.

Thanks in advance,
Bernard Chew
