rbd.waiter.cacher.CacheException: not enough cache space for item

Environment

VMware vCenter Server 7.x
VMware vCenter Server 8.x

Cause

By default, the Auto Deploy Service cachesize_GB is set to 2GB which is increased to 4GB in newer releases.

The cache size is not sufficient for the OFFLINE_BUNDLE which is exported to the ESXi hosts during the register process.

Resolution

Increase the Auto Deploy and Image Builder Service cachesize_GB

  • Log in to the vCenter as local SSO administrator.
  • Navigate to Auto Deploy Menu.
  • Navigate to Configure.
  • Increase the VMware Auto Deploy Service cachesize_GB.
  • Increase the VMware Image Builder Service cachesize_GB.
  • Restart the vmware-rbd-watchdog and vmware-imagebuilder service on the vCenter for the changes to take effect.

Additional Information

Autodeploy and imagebuilder cache can be updated via their respective config files as well.
Service restart is needed for the changes to take effect.

RBD: /etc/vmware-rbd/autodeploy-setup.xml and edit the value for <maxSize> </maxSize>
Imagebuilder: /etc/vmware-imagebuilder/sca-config/imagebuilder-config.props and edit the value cacheSize_GB=

Note: Autodeploy cachesize cannot be more than half of autodeploy partition size.
