[Gluster-users] set owner:group on root of volume

Hi,
By default the owner and group of a GlusterFS seems to be root:root now I changed this by first mounting my volume using glusterfs/fuse on a client and did the following
chmod 1000:1000 /mnt/myglustervolume
This changed correctly the owner and group to UID/GID 1000 of my volume but like 1-2 hours later it was back to root:root. I tried again and this happens again.
Am I doing something wrong here? I am using GlusterFS 3.8.11 on Debian 8.
Regards,
M.

Just found out I needed to set following two parameters:
gluster volume set myvol storage.owner-uid 1000
gluster volume set myvol storage.owner-gid 1000
In case that helps any one else :)

Unfortunately the root directory of my volume still get its owner and group resetted to root. Can someone explain why or help with this issue? I need it to be set to UID/GID 1000 and stay like that.
Thanks

This is an interesting problem. A few questions:

1. Is there any chance that one of your applications does a chown on the
root?

2. Do you notice any logs related to metadata self-heal on '/' in the
gluster logs?

3. Does the ownership of all bricks reset to custom uid/gid after every
restart of the volume?

Thanks,
Vijay

Hi Vijay,
Thanks for your reply. Below the answers to your 3 questions.
1) Rather unlikely as my application does not run as root. That's the point my application runs as UID/GID 1000:1000 and the root of my GlusterFS volume needs to be owned by 1000 so that my application can write there.
2) Nothing in glustershd.log and there was not even a glfsheal-myvolume.log file until I ran "gluster volume heal myvolume info".
3) IIRC yes it does but I will have to test that again tomorrow as I now ran again manually a chown on the root of my volume through a fuse client.
Regards,
M.

I can now also answer your question 3) so I just did a stop and start of the volume and yes the owner and group of the root directory of my volume gets set again correctly to UID/GID 1000. The problem is that it is now just a mater of time that it somehow gets reseted back to root:root...
