(the +glusterfs plugin for samba helps achieve this, without having to re-export +a fuse mounted glusterfs volume). The snapshots of a glusterfs volume can +also be viewed in the windows explorer. + +There are 2 ways: +* Give the path of the entry point directory +(\\<hostname>\<samba-share>\<directory>\<entry-point path>) in the run command +window +* Go to the samba share via windows explorer.

If snapshots have to be seen from subfolders, then +the path should be provided in the run command window. + +For snapshots to be accessible from windows, below 2 options can be used. +A) The glusterfs plugin for samba should give the option "snapdir-entry-path" +while starting. The option is an indication to glusterfs, that samba is loading +it and the value of the option should be the path that is being used as the +share for windows. +Ex: Say, there is a glusterfs volume and a directory called "export" from the +root of the volume is being used as the samba share, then samba has to load +glusterfs with this option as well. + + ret = glfs_set_xlator_option(fs, "*-snapview-client", + "snapdir-entry-path", "/export"); +The xlator option "snapdir-entry-path" is not exposed via volume set options, +cannot be changed from CLI. Its an option that has to be provded at the time of +mounting glusterfs or when samba loads glusterfs. +B) The accessibility of snapshots via root of the samba share from windows +is configurable. By default it is turned off. It is a volume set option which can +be changed via CLI. + +gluster volume set <volname> features.show-snapshot-directory "on/off". By +default it is off. + +Only when both the above options have been provided (i.e snapdir-entry-path +contains a valid unix path that is exported and show-snapshot-directory option +is set to true), snapshots can accessed via windows explorer. + +If only 1st option (i.e. snapdir-entry-path) is set via samba and 2nd option +(i.e. show-snapshot-directory) is off, then snapshots can be accessed from +windows via the run command window, but not via the explorer. + + -------------------------------------------------------------------------------------- |
