Hi Vlad, Can I ask what hypervisor are you using? The default action is to reboot the hosts

Even more, my cluster had a working storage and I added one more, which was not writable due to missing user permissions... So effectively all the VMs hard drive were located on the working storage, but the problem with permissions on the new one causes the entire cluster to reboot :( Is this a bug or a correct behavior? Is it able to avoid rebooting at least?
