You should mount the snapshot with the following command: mount -t glusterfs <hostname>:/snaps/<snapname>/<parent-volname> /mount_point e.g. mount -t glusterfs storage1:/snaps/gvol1-snap1/gvol1 /gluster-client/gvol1-snap1 > > 2) i also tried using uss ( user servicable snapshots ) > gluster volume set gvol1 features.uss enable > returned success but i do not see the .snap dirs in my main mount. .snaps folder is a virtual folder and is not visible in the mount. User need to explicitly cd into the .snaps folder. e.g. if you run "ls -a" on /gluster-client/gvol1-snap1 folder you will not see .snaps folder but you can cd into /gluster-client/gvol1-snap1/.snaps folder. Hope that helps.
