SnapShots
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
Name: Projects-files-projects-1-hr-2019-01-23::16:05:00.000
Volume name: Projects2
Serial number: 4a9fb48e201522b86c9ce900703c8a7f
iSCSI target: iqn.2007-11.com.nimblestorage:projects2-projects-files-projects-1-hr-2019-01-23::16:05:00.000-v7e6b949901e1a8e9.00000080.7f8a3c70.s7e6b949901e1a8e9.00000081.00097fea

Application identifier:
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...

Re: SnapShots
Hi,
I use this command to find and then delete these unmanaged (orphaned) Snaps:
snap --list --unmanaged --all
