COMPONENT NAME
storage
CLOUDSTACK VERSION
4.19.1.0
CONFIGURATION

linstor storage with LVM as backend is used, a second storage is required to reproduce.

OS / ENVIRONMENT

N/A

SUMMARY

Volumes in ACS are created using a path in linstor. That path differs if the volume is not initially created on linstor. However the volume uuid is used for vm snapshot deletions and reverts.

STEPS TO REPRODUCE
  • create an instance outside the linstor storage
  • migrate the instance to linstor
  • create an instance snapshot
  • try to delete or revert the snapshot
  • get an error including stacktrace in the management log stating the ResourceGroup named after the volume uuid is missing
EXPECTED RESULTS
  • The instance snapshot should be either reverted or deleted depending on the action
ACTUAL RESULTS

See steps to reproduce.
