[ovirt-users] How to delete leftover of a failed live storage migration disk

Hello, I had an error during live storage migration of a disk. The destination image was created but the process was not completed, because of a bug in the original version of sw. Then I updated sw but if I try to run again the move of the same disk to the same destination storage domain I get VDSM command HSMGetAllTasksStatusesVDS failed: Cannot create Logical Volume: ('679c0725-75fb-4af7-bff1-7c447c5d789c', 'd2a89b5e-7d62-4695-96d8-b762ce52b379') On destination storage domain, that is empty, from web admin gui I see only the 2 OVF_STORE disks. From OS point of view using lvs I see the leftover LV that oVirt complains not able to create (I suppose because already existent due to the former error) # lvs 679c0725-75fb-4af7-bff1-7c447c5d789c/d2a89b5e-7d62-4695-96d8-b762ce52b379 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert d2a89b5e-7d62-4695-96d8-b762ce52b379 679c0725-75fb-4af7-bff1-7c447c5d789c -wi------- 55.00g I know that I should use the "vdsClient -s 0 deleteVolume " command from the SPM host. the syntax should be # vdsClient -s 0 deleteVolume --help Error using command: list index out of range deleteVolume <sdUUID> <spUUID> <imgUUID> <volUUID>,...,<volUUID> <postZero> [<force>] Deletes an volume if its a leaf. Else returns error I have difficulties to do the exact mapping of the various elements. Is it right what below? sdUUID --> VG name spUUID I can retrieve using: # vdsClient -s 0 getStorageDomainInfo 679c0725-75fb-4af7-bff1-7c447c5d789c uuid = 679c0725-75fb-4af7-bff1-7c447c5d789c type = ISCSI vguuid = nkoZA2-nQOu-oeXX-Phpa-moqh-FWuR-AFAh4B metadataDevice = 36589cfc0000006dd999f5618bf759d3f state = OK version = 4 role = Master vgMetadataDevice = 36589cfc0000006dd999f5618bf759d3f class = Data pool = ['5af30d59-004c-02f2-01c9-0000000000b8'] name = ISCSI_400G so spUUID is the pool --> 5af30d59-004c-02f2-01c9-0000000000b8 in my case ? for imgUUID I don't know a command to retrieve. in my case the target storage domain (ISCSI_400G) in this moment is the master one and I can see it under /rhev/data-center/mnt/blockSD/ and so I find # ll /rhev/data-center/mnt/blockSD/679c0725-75fb-4af7-bff1-7c447c5d789c/images/ total 4 drwxr-xr-x. 2 vdsm kvm 4096 May 10 15:39 530b3e7f-4ce4-4051-9cac-1112f5f9e8b5 So it seems to me in my case imgUUID is 530b3e7f-4ce4-4051-9cac-1112f5f9e8b5 But even if it is right in my particular case, how can I get in general? volUUID ? Is it the LV name corresponding, so in my case d2a89b5e-7d62-4695-96d8-b762ce52b379 ? The result of the vdsCLient command should be the removal of LV also? Thanks in advance for any insight or link to details... Gianluca
