[Linux-cluster] Panic



I have the following panic on two nodes hours apart. Each node Is in a
different state ( as in states of the US ). NO I am not running a cluster
over a WAN, just two separate clusters in two different locations. Files are
written on one cluster and I have a script that does an SCP of the file to
the other cluster. Both machines running the latest RHEL4 with the latest
GFS updates. This just started happening. Happened twice since Friday
morning. Any hints ? What is happening with clvmd here ? What does the
global conflict message mean ?
