[Gluster-users] Ownership changed to root

[Joe Topjian]

Hello,

I'm seeing a weird issue with OpenStack and Gluster.

I have /var/lib/nova/instances mounted as a glusterfs volume. The owner of
/var/lib/nova/instances is nova:nova.

When I launch a vm and watch it launching, I see the following:

root at c01:/var/lib/nova/instances/instance-00000012# ls -l
total 8
-rw-rw---- 1 nova nova    0 Aug 24 14:22 console.log
-rw-rw-r-- 1 nova nova 1459 Aug 24 14:22 libvirt.xml

This is correct.

Then it changes ownership to libvirt-qemu:

root at c01:/var/lib/nova/instances/instance-00000012# ls -l
total 22556
-rw-rw---- 1 libvirt-qemu kvm         0 Aug 24 14:22 console.log
-rw-r--r-- 1 libvirt-qemu kvm  27262976 Aug 24 14:22 disk
-rw-rw-r-- 1 nova         nova     1459 Aug 24 14:22 libvirt.xm

Again, this is correct.

But then it changes to root:

root at c01:/var/lib/nova/instances/instance-00000012# ls -l
total 22556
-rw-rw---- 1 root root        0 Aug 24 14:22 console.log
-rw-r--r-- 1 root root 27262976 Aug 24 14:22 disk
-rw-rw-r-- 1 nova nova     1459 Aug 24 14:22 libvirt.xml

OpenStack then errors out due to not being able to correctly access the
files.

If I remove the /var/lib/nova/instances mount and just use the normal
filesystem, the root ownership part does not happen.

I have successfully had Gluster working with OpenStack in this way on a
different installation, so I'm not sure why I'm seeing this issue now.

Any ideas?

Thanks,
Joe
