cluster/afr: Don't try to self-heal if there are locks held

2009-10-30T11:10:57+00:00

If the inodelk_count or entrylk_count is positive on a
file/directory, don't try to do self-heal on it.

cluster/afr: Move deleted files to /.trash in entry self-heal.

2009-10-29T17:17:19+00:00

If entry self-heal determines that a file/directory should
be deleted from a subvolume, move that entry to a directory
called "/.trash" on that subvolume. This is for two reasons:

1) It limits the damage that can be done by a "wrong" entry
   self-heal.

2) It solves the problem of a to-be-deleted directory not
   being empty.

cluster/afr: Check the target of symlink's in entry self-heal.

2009-10-26T14:09:28+00:00

During entry self-heal, make sure not only that a symlink
exists on all subvolumes, but also that their targets match.

cluster/afr: Set read-subvolume to the source while self-heal is in progress.

2009-10-26T14:09:09+00:00

Just before the lookup is unwound during background data self-heal,
the read subvolume is set to the self-heal source subvol so that
read operations on the file work correctly, and don't have to
wait for the self-heal to complete.

cluster/afr: Do self-heal in the background.

2009-10-26T14:09:05+00:00

This patch introduces a new option "background-self-heal-count", with a
default value of 16.

This means that upto {background-self-heal-count} number of files/directories
will be healed in the background at any given time. If such number of self-heals
are already in progress, further self-heals take place in the foreground.
