storage pool maintenance

[ingox]

Hey all,

no 1:
In the procedure of deleting a primary storage I'd like to disable a primary storage as a first step to avoid further deployments.
As a next step I'd like to put the storage in maintenance. That is not possible as long as it's disabled. Is there any reason for that? The option is not available in the UI and cmk gives an error. You can enable maintenance while pool is enabled only.

no 2:
One additional topic I noticed. Once you put a primary storage in maintenance it will shutdown all the VMs which are still using this storage. The volumes are not migrated off to other storage. In the case I leave the maintenance again all the VMs get started again but also the volumes will be migrated off to a different storage. Why now?

I tested with ACS 4.21; XCP-ng; NFS

Did anyone else experience this?
Best regards,
Ingo
