Dean,
I am guessing you are using NFS for your Primary Storage.
This is actually 'by design'. The logic is that if the storage goes offline,
then all VMs must have also failed, and a 'forced' reboot of the Host 'might'
automatically fix things.
This is great if you only have one Primary Storage, but typically you have more
than one, so whilst the reboot might fix the failed storage, it will also kill
off all the perfectly good VMs which were still happily running.
The fix for XenServer Hosts is to:
1. Modify /opt/xensource/bin/xenheartbeat.sh on all your Hosts, commenting out the two
entries which have "reboot -f"
2. Identify the PID of the script - pidof -x xenheartbeat.sh
3. Restart the Script - kill <pid>
4. Force reconnect Host from the UI, the script will then re-launch on
reconnect
If you running KVM, I'm guessing there is a similar script, but I have not
tried this yet for anything other than XenSever (it does not apply to ESXi)

Subject: Primary storage failure
Hello everyone
I'm testing failure scenarios, and I have noticed that as soon as the primary
storage gets offline.
cloudstack management server seems to think that the hypervisor is not
responding and it will reboot the node, if you have number of of nodes it will
eventually reboot all of them. (losing everything .. fun! )
What if I have multiple primary storage and one of them failed? it will reboot
all of my hypervisors? it doesn't seems right to me.
Is there is a way to control this behavior?
it seems that cloud stack management server needs to be a little smarter.
