[Pacemaker] coronosyc 1.2.1 with pacemaker and openais is suse11sp1

[Timi]

Hi guys,

we have a cluster setup with: coronosyc 1.2.1 with pacemaker and openais is
suse11sp1 on two nodes connected via direct cable for heartbeat, we checked
the connection and its ok.

we are having this on the logs:

12:23] <[1]TT> Apr 03 03:40:52 flexy-db-1 lrmd: [9285]: info:
perform_op:2894: postponing all ops on resource floating-ip by 1000 ms
[12:23] <[1]TT> Apr 03 03:40:52 flexy-db-1 lrmd: [9285]: debug:

[12:23] <[1]TT> Apr 03 03:40:56 flexy-db-1 lrmd: [23698]: debug:
perform_ra_op: resetting scheduler class to SCHED_OTHER


this happens frequently and we believe it causes instability issues as we
sometimes after these logs the:

corosync [TOTEM ] Process pause detected for 5370 ms, flushing membership
messages.



and there it starts to panic and causes the msql to restart each 5 min.

Has anyone any idea what might be causing this.

"corosync [TOTEM ] Process pause detected for 5370 ms" some time ago,
the problem was kernel system use was so hight, you can try to check
using sar, my system was suse 11 sp1 as your.

That wont be affecting corosync.
The logs themselves might be though - debug can be very noisy.
