I did see issues with your storage in the logs previously to the detach issue but they seem to have been resolved so I do not think that they are related.

what I can see in the logs is that the detach fails because the connectStorageServer command, which suppose to mount the storage, fails:

Mount of `172.16.0.5:/home/external/migration` at `/rhev/data-center/mnt/172.16.0.5:_home_external_migration` does not exist

so unless you had a momentary problem in your storage it actually looks like a vdsm bug to me.

adding Eduardo, perhaps he will see something I missed, but I think that its possibly related to this issue: https://bugzilla.redhat.com/show_bug.cgi?id=971291

Thank you very much

I confirm that to solve the problem I had to:

-manually mkdir /rhev/data-center/mnt/172.16.0.5:_home_external_migration
- give it properly permissions
- manually mount the storage of Export Domain in the right place
- detach the SD using oVirt GUI

I looks similar to the ug you point

Thank you for your assistance

Ovirt looks terribly good but it sometimes makes my road longer without any apparent reason

Best regards
