[Cluster-devel] [GFS2 PATCH 00/39] GFS2: Pre-pull patch posting (merge window)

[Bob Peterson <rpeterso@redhat.com>]

Hi,

We've got a lot of patches (39) for this merge window. Most of these patches
are related to corruption that occurs when journals are replayed.
For example:

   1. A node fails while writing to the file system.
   2. Other nodes use the metadata that was once used by the failed node.
   3. When the node returns to the cluster, its journal is replayed,
      but the older metadata blocks overwrite the changes from step 2.

o Fixed the recovery sequence to prevent corruption during journal replay.
o Many bug fixes found during recovery testing.
o New improved file system withdraw sequence.
o Fixed how resource group buffers are managed.
o Fixed how metadata revokes are tracked and written.
o Improve processing of IO errors hit by daemons like logd and quotad.
o Improved error checking in metadata writes.

Regards,

Bob Peterson
