I have gone in an changed the libvirt configuration files on the cluster nodes, which has resolved the issue for the time being.

I can reverse one of them and post the logs to help with the issue, hopefully tomorrow.

No, other devices might have permission problems in such a case.

 

I wonder how libvirt can change the permissions for devices it does not know about?

 

When using libgfapi, we pass libivrt:

 

            <disk name='vda' snapshot='external' type='network'>
                <source protocol='gluster'
                        name='volume/11111111-1111-1111-1111-111111111111'
                        type='network'>
                    <host name="brick1.example.com" port="49152"
                        transport="tcp"/>
                    <host name="brick2.example.com" port="49153"
                        transport="tcp"/>
                </source>
            </disk>

 

So libvirt does not have the path to the file, and it cannot change the permissions.

 

Alex, can you reproduce this flow and attach vdsm and engine logs from all hosts

to the bug?
