Re: [ovirt-users] VMs freeze during vm-host reboot

Hi Michal, That's right. I put it in maintenance mode, so there were no VMs. The frozen VMs were on the other hosts. That's wat makes it strange and why it doesn't give me a good feeling. When someone can say 'I know the issue and it is fixed with gluster version 3.7.12', I would feel more reassured about it...
