[Linux-cluster] fenced spinning?



CentOS 5.2, 26-node cluster.

 

Today I restarted one node.  It left the cluster, rebooted and joined the cluster without incident.  Everything is fine but… fenced has the CPU pegged.

 

No useful log messages.  strace says it is spinning on poll/recvfrom:

 

poll([{fd=4, events=POLLIN}, {fd=6, events=POLLIN, revents=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN, revents=POLLNVAL}], 4, -1) = 2

recvfrom(5, 0x7fffb074ab40, 20, 64, 0, 0) = -1 EAGAIN (Resource temporarily unavailable)

poll([{fd=4, events=POLLIN}, {fd=6, events=POLLIN, revents=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN, revents=POLLNVAL}], 4, -1) = 2

recvfrom(5, 0x7fffb074ab40, 20, 64, 0, 0) = -1 EAGAIN (Resource temporarily unavailable)

 

Anything else useful I can do to diagnose?  What are the chances I can recover this node nicely without making things worse?

 

Any help/ideas appreciated,

 

Jeff
