Hi all,

I'm trying to delete via vdsm-client toolan illegal volume that is not listed in the engine database. The volume ID is 5cb3fe58-3e01-4d32-bc7c-5907a4f858a8:

[root@ovirthost ~]# vdsm-tool dump-volume-chains e25db7d0-060a-4046-94b5-235f38097cd8

             Error: more than one volume pointing to the same parent volume e.g: (_BLANK_UUID<-a), (a<-b), (a<-c)

             Unordered volumes and children:

With the command vdsm-client Volume getInfo I can retrieve the info about the volume 5cb3fe58-3e01-4d32-bc7c-5907a4f858a8:

I can't remove it due to the following error:

vdsm-client Volume delete storagepoolID=c0e7a0c5-8048-4f30-af08-cbd17d797e3b volumeID=5cb3fe58-3e01-4d32-bc7c-5907a4f858a8 storagedomainID=e25db7d0-060a-4046-94b5-235f38097cd8 imageID=4d79c1da-34f0-44e3-8b92-c4bcb8524d83 force=true

(code=309, message=Unknown pool id, pool not connected: ('c0e7a0c5-8048-4f30-af08-cbd17d797e3b',))

If the pool id works in Volume getInfo, it should be correct.

I'm performing the operation directly on the SPM. I searched for a while but I didn't find anything usefull. Any tips or doc that I missed?

What you do looks right. Did you look in vdsm.log? I'm sure there is
more info there
about the error.
