Description Eyal Shenitzky 2019-07-29 08:59:34 UTC 
Description of problem:

Currently, the user cannot remove an unregistered entity.
The only option is to register the entity to a data center and then remove it which is caused for redundant operations.

The problem is when we have a template with a disk that been copied to several storage domains for e.g on SD1 and SD2.

When detaching SD1 the template will be considered as an unregistered entity on 
SD1 but it will also remain on the data center.

When the user will try to re-attach SD1 to that data center and register the template, he will fail because the template still exists.
So now the user has an unregistered template that he cannot remove or register.

Moved to 4.4.1 not being marked as blocker for 4.4.0 and we are preparing to GA.
Comment 2 Eyal Shenitzky 2020-05-18 18:10:53 UTC 
I am surprised that this bug is still on POST, it seems like the system didn't move it to MODIFIED and we missed it.
Re-target to 4.4.0 since all work is done long ago.
Comment 3 Ilan Zuckerman 2020-05-24 10:50:50 UTC 
Eyal, please provide clear reproduction steps for this one.
I tried to follow your description on 4.3, but after detaching and re-attaching a storage domain with template disk on it, i can not see any 'unregistered' templates on it. In fact there are no templates at all on it.
I tried to view the templates both manually from UI and with help of rest API. Both are empty.
Comment 4 Eyal Shenitzky 2020-05-24 11:26:58 UTC 
Steps to reproduce:

1. Create a DC with 2 storage domains (sd1, sd2)
2. Create a VM with disks on SD1
3. Create a template from the VM in step 2
4. Create a floating disk based on SD1
5. Deactivate SD1
6. Detach SD1 without format it
7. Import SD1 back to the DC
8. Under Storage -> Domains -> SD1 -> import VM/Template/Disk select to remove the unregistered entities.
