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.

Handle files which have no pending xattrs at all.

2009-04-09T13:27:05+00:00

If a pending xattr key is non-existent on a file (call such
files 'ignorant'), make all other non-ignorant subvolumes point
towards the ignorant one.

Erase xattr during self-heal based on original dict.

2009-04-09T13:27:01+00:00

Decrement xattr during self-heal based on the original dict instead
of pending_matrix, as the pending_matrix might have been
altered later.

Fix in return value of afr_sh_mark_sources

2009-04-06T16:34:48+00:00

afr_sh_mark_sources now returns:
  -1   if two wise subvols conflict (split-brain)
   0   if all subvols are innocent (no self-heal needed)
  >0   if sources found

Also, changes to callers of afr_sh_mark_sources to handle return
value properly.

Made self heal logic more precise.

Discard earlier patch sent for the same error. This patch fixes
it more comprehensively.

This solves the spurious split-brain seen by many users.
