I wish.
It was a bcachefs array with data replicas being a mix of 1,2 & 4 depending on what was most important, but thankfully I had the foresight to set metadata to be mirrored for all 4 drives.
I didn’t get the good fortune of only having to do a resilver, but all I really had to do was fsck to remove references to non-existent nodes until the system would mount read-only, then back it up and rebuild it.
NixOS did save my bacon re: being able to get back to work on the same system by morning.
Tailscale edits /etc/resolv.conf, since your DNS isn’t working start by making sure that file is how the archwiki suggests rather than what tailscale changes it to.
An uninstalled tailscale may still have left that file modified.
