+++ This bug was initially created as a clone of Bug #1366278 +++

Description of problem:
==========================
as a non-root user i am unable to mount a gluster volume using fuse mount.
Simple USe-case:
I have a common repository of documents in a gluster volume and I want to
access it from my desktop .
The only workaround is to mount as root user, but then the non-root user can't
access all files due to some files having no such permissions

I even tried a blog
https://joejulian.name/blog/mounting-a-glusterfs-volume-as-an-unprivileged-user/

Version-Release number of selected component (if applicable):
===========
mainline

How reproducible:
==============
always

Steps to Reproduce:
===================
1.create a distrep/disperse vol
2.try to mount using fuse on you laptop which fails

1. Have you tried sudo?
2. Are you able to nfs mount a gluster volume as normal user?

This is a downstream only bug(or rather a feature disable).

It was done because of
bug : https://bugzilla.redhat.com/show_bug.cgi?id=989480
patch: https://code.engineering.redhat.com/gerrit/#/c/11113/2

It was decided that a non-root user of fuse mount was not an important use-case
for glusterfs. Considering that it was 3 years ago, and with containers and
hyperconverged use-cases becoming important, do we see a need for this feature
again?

If the feature is not needed, may be we should disable fusermount build option
than changing the suid bit in Makefile.am and also document it somewhere.

Using sudo, means i need to know root password. But I don't want to mount as an
admin. Take a simple case of accessing media files from a common repository for
thousands of users from their desktop which they would have logged as non-root
user.

As Raghavendra already mentioned, we need to think if upcoming technologies
like  hyperconvergence and container world may require this.....though i am not
able to frame a use case at the moment.

Not really. If you have been given privileges (/etc/sudoers configuration?),
you run the command with *your* password.

This BZ having been considered, and subsequently not approved to be fixed at
the RHGS 3.2.0 release, is being proposed for the next release of RHGS

GlusterFS FUSE client uses the "allow_other" mount option which has to be
explicitly enabled for non-priviieged users by adding a line of
"user_allow_other" to /etc/fuse.conf.

See mount.fuse(8),
http://man7.org/linux/man-pages/man8/mount.fuse.8.html#CONFIGURATION

Please make sure this setting is in place and non-root mount again.

That too is not working

nag:x:2006:2006::/home/nag:/bin/bash
[root at dhcp35-126 glusterfs]# cat /etc/fuse.conf 
mount_max = 1000
user_allow_other

nag at dhcp35-126 ~]$ mount -t glusterfs 10.70.35.29:testvol testvol/
mount: only root can use "--types" option
