Hello!
I'm playing with with gluster , so I'm newbie , :-) and trying to use
it for kvm.
I have two hosts, one is Centos 7 - vmhost1 , another RHEL 6.7 - roxar.
I also have two Centos7 lxc containers on vmhost1 each has gluster
3.7.9 installed.
I created VM and it works OK on Centos 7, but on RHEL6 I get i/o error
very quickly:

Image owner was root, I mounted glusterfs and changed owner to qemu,
now everything is OK,
but it is very interesting is there better/right way to fix this?
And why there is difference between RH versions?
Thank you!
ooh, now I can't start VM on Centos7 host:
libvirtError: Cannot access storage file '/vm.img' (as uid:107, gid:107):
And can't change owner from Centos 7 host using fuse:
chown qemu:qemu vm.img
chown: changing ownership of 'vm.img': Input/output error
Although I can do this from RHEL 6 host:
[root@roxar replica]# chown qemu:qemu vm.img
[root@roxar replica]#
why?
Is it possible to access glusterfs volume by different client versions?
