I've been trying to switch my home cluster from Debian + K3s to Talos but keep running into issues.

What does your persistent storage layer look like on Talos? How have you found it's hardware stability over the long term?

Well, for its own storage: it's an immutable OS that you can configure via a single YAML file, it automatically provisions appropriate partitions for you, or you can even install the ZFS extension and have it use ZFS (no zfs on root though).

For application/data storage there's a myriad of options to choose from[0]; after going back and forth a few times years ago with Longhorn and other solutions, I ended up at rook-ceph for PVCs and I've been using it for many years without any issues. If you don't have 10gig networking you can even do iSCSI from another host (or nvmeof via democratic-csi but that's quite esoteric).

>How have you found it's hardware stability over the long term?

It's Linux so pretty good! No complaints and everything just works. If something is down it's always me misconfiguring or a hardware failure.

Curious to know what issues you ran into with Longhorn.

Talos is the Linux kernel at heart, so.. just fine.
