Description

We are using Cloudstack 3.0.2 using KVM on Ubuntu 12.04 with PrimaryStorage over NFS

When we enable Maintenance Mode on a PrimaryStorage and disconnect the storage machine for reconfiguration the heartbeat checks on the KVM lead to an unwanted reboot of KVM Compute Nodes.

The /usr/lib64/cloud/agent/scripts/vm/hypervisor/kvm/kvmheartbeat.sh script is correctly identifying a persistent problem with the disconnected storage pool. The problem is that this pool was intentionally put into maintenance mode and MAY be unavailable.
