cluster/distribute: send proper 'params' dictionary during linkfile creation

2011-07-12T14:12:50+00:00

when the code path enters the 'subvol_filled()' case, local->params is set,
which contains the 'gfid-req' value, but the linkfile creation was not
checking for its existance.

loc_t: add 'gfid' and 'pargfid' fields

2011-06-14T07:13:51+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.

also contains 'Pranith 's patch to set proper
loc->gfid during afr selfheal

cluster/dht: use GFID returned from hashed subvolume

2011-06-09T08:35:38+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.

DHT selheal dir: Recreate dirs with correct gfid.

2011-06-08T18:18:27+00:00

When selfheal of dir is triggered, make sure the dirs are recreated
with the correct gfid, to prevent mismatch of gfids in the backend.

Also, remove the spurious memcpy to inode.gfid

If a older link file exists, unlink it and then create the linkfile.
