The mount point is vrp-db.  Two nodes mount the SAN volume.  An oracle
DB runs on one node at a time (no RAC).  Currently oracle is running
correctly on node2.

on node1 (bad modtimes:)

Both nodes were rebooted this afternoon, so these are fresh mount points.
What on earth is going on here?

(making things worse... before the reboot, node1 had mod times around
Dec 10 2010... which is WAY out of wack, but still better than Feb 20
2008!)
