From 74612a456ad1602f8038fae79fee654eb427602a Mon Sep 17 00:00:00 2001 From: Vikas Gorur Date: Tue, 24 Nov 2009 08:45:09 +0000 Subject: cluster/afr: Do self-heal on reopened fds. 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. Signed-off-by: Vikas Gorur Signed-off-by: Anand V.
