Hi Vlad,

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

This is done in the heatbeat file on xenserver

Subject: Self-fencing when storage not available

Hi All,

I'm testing Cloudstack 4.6 now

When doing some tests with storage (nfs), I was wondering, that the hosts self-fence itself
by reboot, when a storage not writable ...

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?

Thank you in advance
