Hello,
after some further investigation I think I found the reason
but do not know how to fix it best. On my Fedora 19 host
sanlock is running as user sanlock (id 179). That user has
no access to files created by user vdsm (id 36). See logs
attached.
The node installation was done the standard way through
ovirt-engine 3.3. Maybe I missed some setp in the installation
process but I would expect this to work out of the box.
Can anyone tell me what the expected setup is. Should I file
a bug for that?
