When things lock up, will a kill -9 kill rsync or not? If it doesn’t, and the zpool status lockup is suspicious, it means things are stuck inside a system call. I’ve seen all sorts of horrible things with usb timeouts. Check your syslog.

Twitter is a mess that we can see. Imagine all the shit hidden on Tesla software that we can’t.

I like tailscale and have been testing it for a few months. I’m also using headscale as the control plane.

Unfortunately the android client is somewhat unreliable. It works most of the time but once in a while, connections to your tailnet will fail for a bit and require retries. If you ping a machine in your tailnet during this problem, it will show packet loss and then start working after a few pings. This unfortunately makes it difficult to have a reliable split DNS setup.

I’ve done everything to try and understand what happens without success. It seems like state is lost somewhere and a few packets flowing will fix it. Running a constant ping from Android to my tailnet “fixes” the problem, but is not a great workaround.

Just something to keep in mind before you jump headfirst.
