How to determine when it is safe to drop block storage volume/boot volume
Summary:
Have lots of unattached oci block storage and boot volumes that I need to delete. Trying to figure out a way to determine when this is safe to do so.
oci compute bv volume list shows me volumes
oci compute volume-attachment list shows me volume attachments
combining these I can determine what is attached/detached now.
I can get creation dates/times for the volume and the attachment. I would like to determine how long it is since a volume (or boot volume) was attached to an instance.
Reasons it might not be safe to delete a volume:
- It has only just been detached, this was an accident and it will be reattached soon
