I’m not sure, but this seems to have a whiff of a problem we had a while back,
where
we forgot to make appropriate holes in the firewall. GPFS died after the node
had been
up successfully for a while. It worked because connection initiated from the
host to the
GPFS servers, but traffic back to the node was blocked after the session was
dropped from
the firewall table of active connections.
