Hi all...

I'm new to my Nimble and want to make sure I'm not deleting something I shouldn't. I had a case on snapshot retention and I have many snapshots that fall outside of my retention period. The tech explained many ways how this can happen... Resizing a volume, manual snapshots, 3rd party software snapshots... etc. So, I'm looking in the cli and the GUI to confirm a few things before I delete the SS... Is it outside my retention period, is it online and/or is it connected to anything. The tech said something about being "managed" but so far every snapshot I've looked as in the cli shows "Is managed: NO" So, I'm not sure what I'm seeing there.

So, here's an example and what I'm looking for before I delete... Should I be looking at anything else?

My steps.

1. Look in GUI under the Volume and Protection and find a snapshot that falls outside my retention period. 1 year... Make sure there's no online indicator.

2. Run the following in cli: snap --info Projects-files-projects-1-hr-2019-01-23::16:05:00.000 --vol Projects2

Output:

Nimble OS $ snap --info Projects-files-projects-1-hr-2019-01-23::16:05:00.000 --vol Projects2

I look at "Online" and "Initiators connected" In this case I see "No" and nothing so I'm good to delete the snapshot... I do that from the GUI.

Should I be looking at anything else? What exactly does "Is unmanaged" mean? I would think if "Is unmanaged" is NO than it is managed and should have been purged on the retention schedule...

Thanks for your assistance...

Hi,

I use this command to find and then delete these unmanaged (orphaned) Snaps:

snap --list --unmanaged --all
