Description Nithya Balachandran 2018-08-31 05:50:12 UTC

Description of problem:
The earlier version would only return the hashed subvol for an existing file which has limited use.

Change this to perform a getfattr against the directory and provide the filename as part of the xattr name.

COMMIT: https://review.gluster.org/21052 committed in master by "N Balachandran" <nbalacha> with a commit message- cluster/dht:  Rework the debug xattr to get hashed subvol

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.<filename>" <parent dir>

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

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