cluster/dht: act as passthrough for renames on single child DHT

2018-07-05T05:54:11+00:00

Various synchronization present in dht_rename while handling
directories and files is necessary only if we have more than only one
child.

as that of the dht selfheal locks (dictionary order of
lock subvolumes).

cluster/dht: Handle file migrations when brick down

2018-04-18T13:24:30+00:00

The decision as to which node would migrate a file
was based on the gfid of the file. Files were divided
among the nodes for the replica/disperse set. However,
if a brick was down when rebalance started, the nodeuuids
would be saved as NULL and a set of files would not be migrated.

Now, if the nodeuuid is NULL, the first non-null entry in
the set is the node responsible for migrating the file.

cluster/dht: Wind open to all subvols

2018-04-18T13:23:51+00:00

dht_opendir should wind the open to all subvols
whether or not local->subvols is set. This is
because dht_readdirp winds the calls to all subvols.

cluster/dht: Skipped files are not treated as errors

error messages being logged.

cluster/dht: Handle single dht child in dht_lookup

2018-03-05T04:53:14+00:00

This patch limits itself to only handling the case
where no file (data or linkto) exists on the subvol.

Additional cases to be handled:
1. A linkto file was found on the only child subvol. This currently
calls dht_lookup_everywhere which eventually deletes it. It can be
deleted directly as it will not be pointing to a valid subvol.
2. Directory lookups - locking might be unnecessary in some cases.
