Sangeetha Hariharan commented on CLOUDSTACK-5429:
-------------------------------------------------
The same behavior is noted in the cases when network is disconnected from a KVM
host.
This results in host reboot.
Host reboot and it fails because of being stuck at trying to unmount nfs
mount points.
Attaching screenshot.
In this case , we need to manually power off and then power on the host once.
> KVM - Primary store down - Hosts attempt to reboot becasue of primary store
> being down hangs.

> KVM - Primary store down - Hosts attempt to reboot becasue of primary store
> being down hangs.
> Set up:
> Advanced zone with KVM (RHEL 6.3) hosts.
> Steps to reproduce the problem:
> 1. Deploy few Vms in each of the hosts with 10 GB ROOT volume size , so we
> start with 10 Vms.
> 2. Create snaposhot for ROOT volumes.
> 3. When snapshot is still in progress , Make the primary storage unavailable
> for 10 mts.
> This results in the KVM hosts to reboot.
> But reboot of KVM host is not successful.
> It is stuck at trying to unmount nfs mount points.
