* storage/posix: Added janitor thread.Vikas Gorur2009-12-024-17/+16
| | | | | | | | | | | | | | | | | | The janitor thread deletes all files and directories in the "/" GF_REPLICATE_TRASH_DIR directory. This directory is used by replicate self-heal to dump files and directories it deletes. This is needed because letting replicate walk the directory tree and delete a directory and all its children is too racy. Instead, replicate self-heal only does an atomic rename(), and the janitor thread takes care of actually deleting them. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V.

* cluster/afr: Do self-heal on reopened fds.Vikas Gorur2009-11-2410-229/+699
| | | | | | | | | | | | | | | | | | | | | | | 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 <vikas@gluster.com> Signed-off-by: Anand V.

* cluster/afr: Ensure directory contents are in sync during opendir.Vikas Gorur2009-11-135-10/+281
| | | | | | | | | | | | | | | | | | | | | | The problem: If some files on the first subvolume disappeared without leaving a trace in the entry changelog (this can happen, for example, when an fsck has deleted files or when a hard drive is replaced), those files would never be self-healed even though they would be present on the second subvolume. This is because readdir is sent only to the first subvolume, and since the files don't appear in the directory listing, no lookup would ever be sent on them. This patch fixes this problem by doing a readdir on all the subvolumes during the first opendir on a directory inode. If a discrepancy in the contents is detected, entry self-heal in a special "force merge" mode is triggered on that directory. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V.
