I tried moving some disks from one gluster volume to another. 8 worked, 6 failed. I can't retry the move because ovirt says: 2019-02-14 21:36:49,450-08 ERROR [org.ovirt.engine.core.bll.tasks.SPMAsyncTask] (DefaultQuartzScheduler4) [2d9789d1] BaseAsyncTask::logEndTaskFailure: Task '2a0e703b-0239-41f8-a920 -50c1ae096590' (Parent Command 'CreateImagePlaceholder', Parameters Type 'org.ovirt.engine.core.common.asynctasks.AsyncTaskParameters') ended with failure: -- Result: 'cleanSuccess' -- Message: 'VDSGenericException: VDSErrorException: Failed in vdscommand to HSMGetAllTasksStatusesVDS, error = Volume already exists: ('d33e8048-a4b4-4b85-bf44-20be65b854f2',)', How do I clear up the gluster volume of these failed images?
