[Linux-cluster] Again DLM messages and high load

[Bas van der Vlies]

WE are using:
  GFS         : CVS 1.0.3 stable
  kernel      : 2.6.17.11-sara1
  NFS-daemons : 128
  GFS-servers   : 5

This node was the master and when this message was displayed, the load 
will rise to the number of NFS daemons and nfs does not work more. We 
had to reboot the node:
  Oct 25 03:12:31 ifs4 kernel: dlm: lisa_vg5_lv1: cancel reply ret 0
  Oct 25 03:12:31 ifs4 kernel: lock_dlm: unlock sb_status 0 2,a45325d 
flags 0
  Oct 25 03:12:31 ifs4 kernel: dlm: lisa_vg5_lv1: 
process_lockqueue_reply id a50a027c state 0

I had to reboot the master node (ifs4) when the node went down the other 
nodes re-elected another master. 3 nodes use the same master and on one 
node has another master. Is this oke?:

node 1,2,4
Fence Domain:    "default" 1   2 run       - [5 2 1 3 4]

node 3:
Fence Domain:    "default" 1   2 run       - [2 5 1 3 4]

cman_tool nodes is the same for all nodes.


Regards
