[ovirt-users] importing local storage domain problem

Hello, I had a lab environment in 4.4.10, composed of only one host and local storage DC and with an external engine. I had 3 disks on this system, with OS in the first one and local storage domains in the second and third one. I detached the storage domains (I forgot to remove them afterwards) from the original env Afterwards I created a completely new engine on 4.5 (not using any backup) and then I reutilized the host installing the OS in the first disk overwriting the previous env. I have mounted the filesystems for the storage domains on the second and third disk as before, but I see that if I try to execute "import storage domain", the local type is not there. And if I select "new storage domain" I receive the error operation canceled Error while executing action New Local Storage Domain: Error in creating a Storage Domain. The selected storage path is not empty (probably contains another Storage Domain). Either remove the existing Storage Domain from this path, or change the Storage path). Is there any file I can delete from the directory tree that reproduces the "removal" action I forgot? Or any workarounds? Thanks in advance, Gianluca
