Hi, We are running ovirt 4.3 and whenever we create a new VM, we get the error: HSMGetAllTasksStatusesVDS failed: Error creating a new volume: (u"Volume creation 77be733a-a38a-4125-a3ae-beea960d9e28 failed: (28, 'Sanlock resource write failure', 'No space left on device')",) 3/8/2111:56:57 AM I have checked the engine logs and see the following: 2021-03-08 12:09:18,306+01 ERROR [org.ovirt.engine.core.bll.tasks.SPMAsyncTask] (EE-ManagedThreadFactory-engineScheduled-Thread-40) [] BaseAsyncTask::logEndTaskFailure: Task 'd4aa81a1-9adc-45c9-be46-05bc63862f4e' (Parent Command 'Unknown', Parameters Type 'org.ovirt.engine.core.common.asynctasks.AsyncTaskParameters') ended with failure: -- Result: 'cleanSuccess' -- Message: 'VDSGenericException: VDSErrorException: Failed to HSMGetAllTasksStatusesVDS, error = Volume does not exist: (u'46bf0806-8d16-40db-92df-8436f43628a4',), code = 201', -- Exception: 'VDSGenericException: VDSErrorException: Failed to HSMGetAllTasksStatusesVDS, error = Volume does not exist: (u'46bf0806-8d16-40db-92df-8436f43628a4',), code = 201' Not sure how to solve this issue. I have tried restarting the engine, but that did not solve it. Any tips? Thanks.
