Description Nag Pavan Chilakam 2016-08-11 13:40:30 UTC

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):
===========
3.7.9-10

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?

Comment 4 Nag Pavan Chilakam 2016-08-11 15:53:05 UTC

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.

Comment 9 Csaba Henk 2017-01-31 06:14:50 UTC

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.

Still waiting for answer to comment 9 from Nag.

That too is not working


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


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

Comment 13 Csaba Henk 2017-09-01 19:23:48 UTC

OK, now with the proper fuse.conf, can you please try the method Joe Julian suggested? That should work now.

If it works, is that an acceptable resolution for you?
