Description Raghavendra Bhat 2019-03-31 15:19:39 UTC
Description of problem:

Ability to take file level snapshots for a single brick volume.
Using setxattr interface, provide a mechanism to take snapshots of file(s).
The same setxattr interface can be used to delete the snapshots as well.

Ex: setfattr -n glusterfs.snapshot -v <snapshot name> <file path>
    setfattr -n glusterfs.removesnap -v <snapshot name> <file path> 

The snapshots can be viewed from <mount point>/.fsnaps/<gfid of the file>
