Title:
VMwareVCDriver: snapshot failure when host in maintenance mode
Status in OpenStack Compute (Nova):
Fix Released
Status in OpenStack Compute (nova) havana series:
In Progress
Status in The OpenStack VMwareAPI subTeam:
In Progress
Bug description:
Image snapshot through the VC cluster driver may fail if, within the
datacenter containing the cluster managed by the driver, there are one
or more hosts in maintenance mode with access to the datastore
containing the disk image snapshot.
A sign that this situation has occurred is the appearance in the nova
compute log of an error similar to the following:
2013-08-02 07:10:30.036 WARNING nova.virt.vmwareapi.driver [-] Task
[DeleteVirtualDisk_Task] (returnval){
value = "task-228"
_type = "Task"
} status: error The operation is not allowed in the current state.
What this means is that even if all hosts in cluster are running fine in
normal mode, a host outside of the cluster going into maintenance mode may
lead to snapshot failure.
The root cause of the problem is due to an issue in VC's handler of
the VirtualDiskManager.DeleteVirtualDisk_Task API, which may
incorrectly pick a host in maintenance mode to service the disk
deletion even though such an operation will be rejected by the host
under maintenance.
