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

[bertjan]

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...

Regards,

Bertjan
