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

dht-rename: Unlink older link files before creating new one

2011-05-31T16:13:02+00:00

If a older link file exists, unlink it and then create the linkfile.
This will prevent mis-match of gfid's.

DHT: Propogate error if dht_rmdir_opendir_cbk

2011-04-18T06:44:40+00:00

Earlier rmdir would succeed on all up subvols, but fuse would get an
error if one of the subvol was down. In follow up lookup, self heal
would be triggered, and since st_mode would be 0, the permissions
would be bad. The behaviour now is to fail rmdir if subvol is down
