Hi-
I have a 16 node cluster that has been rebooting all nodes in the cluster.
I
recevied a seg-fault from multipathd on one node and then all nodes in the
cluster
rebooted. Here is the error message that appeared on all nodes:

Mar 13 13:33:00 bws01 kernel: (4586,0):ocfs2_dlm_eviction_cb:98 device
(253,0): dlm
has evicted node 8
Why would this cause all nodes in the cluster to reboot? Seems to me that
it should have kicked out node 8 only...
thanks
Andrew
