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:

How do I clear up the gluster volume of these failed images?

I'm running :

ovirt-engine-4.1.8.2-1.el7.centos.noarch
glusterfs-3.8.15-2.el7.x86_64
vdsm-4.19.43-1.el7.centos.x86_64

Some errors from the first failed disk move:
