You do you, but I'm holding out for it... and only in fully automated, luxury, gay form.

I would absolutely not trust BTRFS's implementation. Maybe things are better now but it earned the backronym Bro The RAID Fuckin Sucks for a reason.

RAID is not a backup.

RAID is not for data safety.

RAID is for:

  1. Ensuring availability of data in the face of hardware failure. That means your files don't disappear when a drive dies and you have some time to swap out for functional hardware and restore redundancy.
  2. Presenting multiple drives as one larger unit. This is what striping does, and to a lesser extent the parity-mode levels.
  3. Improving performance (sometimes). A RAID mirror is generally much faster to read from than any individual drive because reads can be interleaved across drive members. A stripe can be much faster because writes are distributed across drive members. This is less of a bonus today with solid state/nvme drives, but it's still applicable to spinning rust.

If your concern is protecting your data, set up a 3-2-1 backup strategy.

I have an actual rubber duck for that. I hate it when my colleagues interrupt me just because they forgot how lambdas work

That depends on what level of HA you want to end up with.

If you want proper HA, you'll want to plan on adding a (small, like a Raspberry Pi) third node for quorum. If you are already taking backups and you just want "I can restore on the second system" then it's slightly simpler, but mostly the same process:

  • Setup new node, add to cluster
  • Migrate all VMs and LXCs to new node
  • Remove and upgrade other node
  • Add rebuilt node to cluster

If you're planning on proper HA, I'd strongly advise having the proxmox installation on a second small drive on each node and leaving your 1tb drives as data only.

This article half-explains one option for a two node setup (zfs replication), which is functional but not ideal. If you want to get your feet wet with Ceph then I can give you some pointers.

Randall seems to have aimed at recognisability in choosing those song titles.

Reflection is one of my favorites, super underrated even amongst Tool fans IMO.

He's talking about that shady coyote who's always chasing after that flightless bird.

Maybe the United States should pass laws that force public utilities to be owned by the public and operated as a nonprofit?

Idk, Miles Dyson was able to engineer a neural-net processor with room temperature superconductors all the way back in 1995...
