dht: utilize the framework to pass-through xlator tasks

2018-09-19T04:26:55+00:00

Also fixes the issue caused due to not converting back the fn function
to after getting its address. We wanted the value of the field, not
the address of the pt_fop field.

With this patch, DHT will always be started in pass-through
mode if the number of subvols is just 1.

Fixes some tests to make sure DHT is in full config (ie, subvols > 1).
  - increased timeout of brick-mux test as it was bordering on 300 seconds.
  - Also change the volume type to supported 'replica 3' from 'replica 2'.
  - also no DHT tests should assume presence of DHT when there is
    just 1 brick in volume

cluster/dht: Rework the debug xattr to get hashed subvol

2018-09-07T08:55:32+00:00

The earlier implementation required the file to already exist
when trying to get the hashed subvol. The reworked implementation
allows a user to get the hashed subvol for any filename, whether
it exists or not.

Usage: getfattr -n "dht.file.hashed-subvol." 

Eg:To get the hashed subvol for file-1 inside dir-1

getfattr -n "dht.file.hashed-subvol.file-1" /mnt/gluster/dir1

cluster/dht: refactor dht_lookup

2018-06-21T05:35:41+00:00

The dht lookup code is getting difficult to maintain
due to its size. Refactoring the code will make it
easier to modify it in future.

cluster/dht: avoid overwriting client writes during migration

2018-02-02T15:24:38+00:00

For more details on this issue see
https://github.com/gluster/glusterfs/issues/308

Solution:
This is a restrictive solution where a file will not be migrated
if a client writes to it during the migration. This does not
check if the writes from the rebalance and the client actually
do overlap.

If dht_writev_cbk finds that the file is being migrated (PHASE1)
it will set an xattr on the destination file indicating the file
was updated by a non-rebalance client.
Rebalance checks if any other client has written to the dst file
and aborts the file migration if it finds the xattr.
