Unable to cleanup FlexCache relationship due to Bug 1354671

cluster::*> volume flexcache origin cleanup-cache-relationship -origin-vserver svm_name -origin-volume vol_name -cache-vserver svm_name -cache-volume volume_name_cache
Warning: This command only needs to be run if "volume flexcache delete" fails on
         the FlexCache cluster and prompts you to run this command. The cache
         configuration will be deleted and cannot be reestablished for the
         cache relationship between origin of a FlexCache volume
         "volume_name" in Vserver "svm_name" and FlexCache volume
         "volume_name_cache" in Vserver "svm_name". Running this
         command unless guided by the "volume flexcache delete" command or
         NetApp Support can lead to unwanted outcomes.

[Job xxxx]:  Metadata cleanup job for origin of a FlexCache volume "volume_name_cache" in Vserver "svm_name" queued.

Error: command failed: Cannot cleanup origin of FlexCache volume "volume_name_cache" in Vserver "svm_name", because
the volume is currently in use by another FlexCache operation. Wait a few minutes, then try the command again. If
the problem persists, contact technical support for assistance.
