            Bug ID: 1344551
           Summary: Automount fails because /sbin/mount.glusterfs does not
                    accept the -s option
           Product: GlusterFS
           Version: 3.7.12
         Component: fuse
          Keywords: Triaged

+++ This bug was initially created as a clone of Bug #1340936 +++

Description of problem:
automounting fails with the following error:

$ ls /lan/storage.lan.example.net/repos
ls: cannot open directory /lan/storage.lan.example.net/repos: Too many levels
of symbolic links


Version-Release number of selected component (if applicable):
3.8rc2

How reproducible:
100%

Steps to Reproduce:
0. install the autofs package
1. save the attached auto.lan as /etc/auto.lan and make executable
2. add a file /etc/auto.master.d/lan.autofs with the following contents
    /lan    /etc/auto.lan
3. enable the autofs service
4. access /lan/<storage-server>/<volume>/

Actual results:
Too many levels of symbolic links

Expected results:
access through /lan/... should just work

Additional info:
Enable debugging by putting OPTIONS="-d" in /etc/sysconfig/autofs and restart
autofs:

    fuse: accept the -s option to allow automounting

    autofs passes the -s option when mounting. All /sbin/mount.<fs> helpers
    accept this, except mount.glusterfs. Because the helper fails when -s is
    passed accessing the mountpoint through autofs gives the following
    error:

      $ ls /lan/storage.lan.example.net/repos
      ls: cannot open directory /lan/storage.lan.example.net/repos: Too many
levels of symbolic links
