Abhinandan Prateek commented on CLOUDSTACK-3367:
------------------------------------------------

The heartbeat script should only be modified after we fix the issue of stopping that VMs that are running on that storage. Without a reboot these VMs will become inconsistent. I think it should be classified as an improvement.

> As the title says: if only one of the primary storages fails, all XenServer hosts get rebooted one by one. Because i have many primary storages, which are/were running fine with other VMs, rebooting XenServer Hipervisor is an overkill. Please disable this or implement just stopping/killing the VMs running on that storage and try to re-attach that storage only.
> Problem was reported on the mailing list, as well as a workaround for XenServer. So i'm not the only one hit by this "bug/feature". Workaround for now is as follows:
> 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
