Hi all!
I have a problem with 3 nodes cluster. When I run "fence_node node1" the
node1 reeboot by drac succesfully. When node1 restarts then gets frozen:
------------------
starting clvmd: dlm: got connection fron 32
dlm: connecting to 33
dlm: got connection fron 33
[frozen]
* cman_tool services shows:
type level name id state
fence 0 default 0001001f none
[31 32 33]
dlm 1 clvmd 00010020 none
[31 32 33]
dlm 1 rgmanager 00020020 none
[32 33]
It seems rgmanager has not 31 (?)
* clustat shows:
Member Status: Quorate
Member Name ID Status
------ ---- ---- ------
xenr3u1.domain.com 31 Online
xenr3u2.domain.com 32 Online, Local
xenr3u3.domain.com 33 Online
-------------------
Then I rebooted again the node1:
Starting cluster
Loading modules DLM .......
done
starting ccsd
starting cman
starting daemons
starting fencing
[frozen again]
after long time starting fencing [done] but cman_tool services fails
* cman_tool services shows:
type level name id state
fence 0 default 0001001f FAIL_ALL_STOPPED
[31 32 33]
dlm 1 clvmd 00010020 FAIL_STOP_WAIT
[31 32 33]
dlm 1 rgmanager 00020020 FAIL_STOP_WAIT
* clustat shows:

/etc/init.d/rgmanager restart
Shutting down Cluster Service Manager...
Waiting for services to stop:
[long timeeeeeeee]

I saw this page translated to english
(http://translate.google.com/translate?u=http%3A%2F%2Fken-etsu-tech.blogspot.com%2F2007%2F11%2Fred-hat-cluster-kernel-xen.html&langpair=ja%7Cen&hl=es&ie=UTF-8).
It's exactly the same. A kernel bug? clvmd bug?

Sometimes the node starts ok and cman_tool is also ok.

That's all ;-)
