storage/posix: Add virtual xattr to fetch path from gfid
The gfid2path infra stores the "pargfid/bname" as on xattr value for each non directory entry. Hardlinks would have a separate xattr. This xattr key is internal and is not exposed to applications. A virtual xattr is exposed for the applications to fetch the path from gfid. Internal xattr: trusted.gfid2path.<xxhash> Virtual xattr: glusterfs.gfidtopath getfattr -h -n glusterfs.gfidtopath /<aux-mnt>/.gfid/<gfid> If there are hardlinks, it returns all the paths separated by ':'. A volume set option is introduced to change the delimiter to required string of max length 7. gluster vol set gfid2path-separator ":::" Updates: #139 Change-Id: Ie3b0c3fd8bd5333c4a27410011e608333918c02a Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: https://review.gluster.org/17785 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com>
