[Linux-cluster] GFS Problem: invalid metadata block



Hello,

I have been evaluating a GFS cluster as an NFS solution and have unfortunately run in to a serious problem which I cannot explain.  Both of the GFS filesystems I am exporting became corrupt and unusable.

The system is Redhat AS4 with 2.6.9-42.0.2.ELsmp.  I cannot find anything unusual on the host or the SAN at the time of this error.  Nobody was logged in to the nodes.

Can anyone help me understand what is happening here?

Here are the logs:
