DHT rename: Recreate linkfile after unlink

2011-08-04T04:57:38+00:00

This is done, so that there is no gfid mismatch. Unlink the older
linkfile if it exists, and recreate it with the correct gfid.

Also removed unused rename related code.

cluster/dht: dht_rename() - handle GFID situations

2011-07-25T16:22:42+00:00

In the pre-GFID era, the linkfile of the destination file could be reused
the linkfile for the renamed file when dst_cached == src_cached.
This patch handles this situation and reverts the previous (wrong) fix.

loc_t: add 'gfid' and 'pargfid' fields

2011-06-14T07:13:43+00:00

these fields are used mainly in case of selfheal path, where
'inode->gfid'||'parent->gfid' is not yet set.

These fields in 'loc' will have lower precedence than 'inode->gfid'
in client protocol.

cluster/dht: use GFID returned from hashed subvolume

2011-06-09T08:35:30+00:00

.. to perform lookups on remaining subvolumes. This way, if there is a
race between two clients to 'fix' GFIDs with gfid-req, then the hashed
subvolume will arbitrate and return the winner in stbuf->ia_gfid. This
patch uses the returned gfid as the new gfid-req thereby preventing
mismatching GFIDs on other servers due to further races.
