Subject: [Users] Removal of hard disk doesn´t trigger removal of underlying snapshots


Hi,


and if you later try to remove the snapshot, after you have removed
the hard disk, the response given is "General command validation
failure". Bug?



In general when you remove the VM's disk it should remove all disk's snapshots as well.
Could you please explain what you exactly did and how?
In additional, please share with us vdsm log from your host (SPM) and engine's log

Yeaow, that was yesterday so those logs are long archived and would take a while to search through and find something that I´m not really sure what I should be looking for. But I can tell you what I did:

1. Created new Desktop VM, with thin hard drive
2. Created a snapshot after mucking around a bit
3. Removed hard drive (needed to start over fresh)
4. Snapshot was still present so that´s when I tried to delete it, and was stopped by said error message.

I understand that the sanity-checking fails, since the hard drive is no longer present, hence the validation failure. But maybe it could be neat if it could reply something like "You know, I can´t find the hard drive that goes with the snapshot you want to delete. Could that be because you´ve already deleted it?" and check "Yes, I have." and then "OK". How does that sound?
