[vcenter] After a failover nova-compute searches for images in a new directory
|
||||
==============================================================================
|
||||
|
||||
When you use VMWare vCenter as a hypervisor, nova-compute uses vCenter datastores for the image cache.
|
||||
By default, the image cache directory is configured with a ``$my_ip_base`` value.
|
||||
When nova-compute is moved to another controller node due to a manual service restart
|
||||
with ``pcs resource disable ..`` or a failover, a new empty cache directory appears
|
||||
in the datastore. Because Nova starts downloading images to cache before it can start
|
||||
virtual machines, the virtual machines boot slower. The fix adds a new configuration option
|
||||
``cache_prefix`` to denote which cache directory a particular nova-compute instance must use.
|
