Subject [jira] [Updated] (CLOUDSTACK-155) Storage HA checks cause Compute Node reboot when storage in Maintenence Mode
Date Thu, 20 Sep 2012 09:13:07 GMT

     [ https://issues.apache.org/jira/browse/CLOUDSTACK-155?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jarosław Dzbęk updated CLOUDSTACK-155:
--------------------------------------

    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.
