Possible to "reset" Kubernetes?

[indivision]

I seem to have broken my Kubernetes by deleting snapshots. Explained here: https://www.truenas.com/community/threads/how-to-get-rid-of-12000-snapshots.101048/

So, now I have a new question:

Is there a way to restore Kubernetes functionality? Perhaps by removing all apps and snapshots and starting with a blank slate?

What I've been doing:

1. Apps > Settings > Unset Pool
2. remove entire top-level “ix-applications” dataset
3. Apps > Settings > Choose Pool

Now I get to learn if/how that's getting me into trouble.

Thank you. This worked for me as well.

There is also another option:
You can change the "cluster CIDR" back and forth, as stated above those settings this also wipes (part of) the kubernetes system.
But indeed the complete deleting is a more "certain" way to get a fresh start :)

I moved all my data to a new pool and also ran into some trouble with this. I tried to do what jct suggested (unset pool, remove dataset) but I always get this errormesasge :

[EBUSY] Failed to delete dataset: cannot unmount '/mnt/Marge/ix-applications/docker': pool or dataset is busy cannot unmount '/mnt/Marge/ix-applications': pool or dataset is busy

No idea if the folIowing would helpm but I was about to remove all docker images I can see in "applications - manage docker images" but I noticed some docker images I'm not sure I can just delete (like openebs/zfs-driver:2.0.0).

I don't have any apps or docker images yet I care about, so I just wanted to get a fresh start with kubernetes...

Well, seems all it needed was a reboot. After this I was able to remove the “ix-applications” dataset and start from scratch.

noob here having trouble getting tailscale to get out of deploying after a new router and modem install. what do you mean "remove entire top-level ix-applications dataset?"

what do you mean "remove entire top-level ix-applications dataset?"

Under Datasets, you should see on the pool you selected for Apps that you have a dataset called ix-applications.

Delete it.
