[Ocfs2-users] High load spikes when ocfs2dc cpu spike

[Michael Huot]

We had upgraded from OEL5.3 to OEL5.11 on node 3 of the 3 nodes and converted the multipathing from EMC Powerpath to native dm-multipathing also on node 3 only, I know too much at once.   We had tested this on a 2 node dev cluster and did not see this. We see the high load behavior on 2 of the 3 simultaneously(nodes 1 and 3). We did a packet capture of port 7777 and see a large amount of traffic from the two busy nodes with node 2.There are 19 file systems and the ocfs2dc pid is associated with the first file system from what we can tell. What else can we look at?

Thanks,

Mike
