Add some -vvvvvvv flags to the gfs_fsck command line. Each "v" adds
another layer of messages. The DEBUG messages are at layer 7. This
should print out more information about the resource group that it is
failing to read.

It would be interesting to see if the partitions are identical after the
snapshot. How large are the LUNs? Can you do a comparison of the
volumes? I would do those steps first before the fsck. It is possible
you have a problem with the oracle_u02, so would be interesting to run
gfs_fsck if the snapped LUNs are identical.
