-----------------------------------------
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.
