replicate: replace first-write-to-flush optimization

2010-10-18T10:25:46+00:00

use a changelog piggybacking optimization instead of first-write-to-flush
optimization and do other cleanups (removal of post-post-op hook etc.)

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

2009-11-25T14:03:39+00:00

This patch completes the previous patch for self-heal of
open fds in replicate.

If an fd was never opened on a subvolume, we remember that
and do the open after we've done self-heal on that fd.

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.
