BUG: 361 (GlusterFS 3.0 should work on Mac OS/X)

cluster/afr: Set the self-heal "source" as read subvolume even when not doing self-heal.

2009-12-01T14:30:00+00:00

This patch sets the read-subvolume equal to the self-heal "source"
even if we're not doing self-heal (because some one else is already
doing it).

cluster/afr: Do self-heal on reopened fds.

2009-11-24T14:40:08+00:00

This patch brings in partial support for self-heal of open
fds. The precondition is that the fd should have been opened
successfully during the initial open() (or create()), and we
assume that protocol/client has successfully reopened the fd
when the subvolume comes back up.

It works by doing an "up/down flush" (a dummy flush transaction
to do post-op wherever necessary) and then triggering
data self-heal on the file in the post-post-op hook of the
dummy flush transaction. This ensures that any writes
that come in during self-heal will wait until self-heal completes.

The up/down flush is also done when a subvolume goes down,
so that post-op is done on all subvolumes where pre-op was done.

Compulsorily do self heal if file sizes differ.

2009-04-09T13:27:08+00:00

If file sizes differ, then compulsorily do self-heal. If no 'wise'
sources are found, then pick a 'fool' with the biggest file size.
If even 'fools' aren't found, pick the 'innocent' source with the
biggest file size.
