             Summary: Storage HA checks cause Compute Node reboot when storage in Maintenence
Mode
                 Key: CLOUDSTACK-155
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-155
             Project: CloudStack
          Issue Type: Bug
          Components: KVM, Volumes
    Affects Versions: pre-4.0.0
            Reporter: Jarosław Dzbęk



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.
