[Linux-cluster] Rgmanager fails to restart



Hi!

Sometimes, when I have cleanly shut down rgmanager on one node, and the
services have nicely migrated to other nodes, trying to start rgmanager
fails. Trying to access /dev/misc/dlm_rgmanager results in "No such
device". clurgmgrd concludes that locks are not working and exits.
(See strace output attached.)

--cut--
[jmmpelto pcn1 ~]$ sudo service rgmanager start
Starting Cluster Service Manager:                          [  OK  ]
[jmmpelto pcn1 ~]$ sudo service rgmanager status
clurgmgrd dead but pid file exists
--cut--

Trying to stop cman fails:

--clip--
[jmmpelto pcn1 ~]$ sudo service cman restart
Stopping cluster: 
   Stopping fencing... done
   Stopping cman... failed
/usr/sbin/cman_tool: Error leaving cluster: Device or resource busy
                                                           [FAILED]
Starting cluster: 
   Loading modules... done
   Mounting configfs... done
   Starting ccsd... done
   Starting cman... done

   Starting fencing... done
                                                           [  OK  ]
--clip--

And indeed, the rgmanager that isn't there is there:

--clip--
[jmmpelto pcn1 ~]$ sudo cman_tool services
type             level name       id       state       
fence            0     default    00010001 none        
[1 2 3 4 100]
dlm              1     clvmd      00010002 none        
[1 2 3 4 100]
dlm              1     rgmanager  00020002 none        
[1 2 3 4]
--clip--

If I say 'cman_tool leave force', it succeeds. But if I then try starting the cluster:

--cut--
[jmmpelto pcn1 ~]$ sudo service cman start
Starting cluster:
   Loading modules... done
   Mounting configfs... done
   Starting ccsd... done
   Starting cman... done
   Starting daemons... done
   Starting fencing... failed

                                                           [FAILED]
--cut--

Log (oops, I forgot to shut down clvmd there... it would have gone down cleanly):

--cut--
Jul  1 14:11:02 pcn1.mappi.helsinki.fi ccsd[4427]: Initial status:: Inquorate

--cut--

Thereafter, one of the other nodes fences this one:

--cut--
Jul  1 14:11:50 pcn1.mappi.helsinki.fi init: Switching to runlevel: 0
Jul  1 14:11:50 pcn1.mappi.helsinki.fi ccsd[4427]: Unable to connect to cluster infrastructure after 30 seconds.
Jul  1 14:11:52 pcn1.mappi.helsinki.fi rgmanager: [667]: <notice> Cluster Service Manager is stopped.
--cut--

(Now I wonder where that rgmanager log line came from? It isn't from any
clurgmgrd, I checked with ps that there were none running.)

Any ideas?
