<![CDATA["Orphan VDIs" and "VDIs attached to Control Domain" Safe to delete all?]]>Hey,

Is it safe to forget all "Orphan VDIs" and "VDIs attached to Control Domain" under Dashboard/Health?

Can it hurt any running vm's?

If your orphaned VDI is in use, it will error out with "VDI in use".

so as far as i am aware there are three situations where a VDI should show up on this "Orphan VDIs" list when its not actually Orphaned.

  1. during a cross pool migration (maybe normal disk migrations?)
  2. during some types of backups
  3. fast cloning a VM
  4. maybe more?

so lets just say someone thinks they are being "helpful" and wants to clean up what they think is a mess in this "Orphan VDIs" section.. and just deletes everything in it.... and now people are going to have a bad day if any of the above situations were listed...

please feel free to correct me if I am wrong here.

and if i'm not wrong, can there be some checks put in XOA to NOT allow deletion of "Orphan VDIs" that are not actually orphaned?

I would think it would work on XCP-ng, as well. https://raw.githubusercontent.com/deepix/shell-fu/master/orphan_vdi.bash

don't VID's show up as "orphan"'ed during a cross pool migration? if that's the case a person should make sure no migration or backup tasks are running before deleting. correct?

During backup process the VDI need to be downloaded by XOA so it is attached to dom0 and downloaded from there. Normally this VDI should be detached after the backup is finished but if you have backup error the VDI could stay stuck attached to dom0.

So in your case if you have backup Running be careful with this VDI but if they are old VDI you can safely remove them.

That isn't normal behavior. If this were my host, I would be investigating why this is occurring.

What version of CH / XCP-ng are you running? Is it fully patched?

This isn't the case with VDIs attached to Control Domain, which likely belong to an active VM.
