My Raspberry Pi, on which I host a Minecraft server, suddenly froze. I cannot not SSH in, nor can I join the Minecraft server. I ran the Minecraft server in Docker, via itzg/docker-minecraft-server. I turned off the Raspberry Pi, took out its microsd and plugged it into my PC, to at least attempt to run the Minecraft server from my PC to see if I still have the data. I tried to copy it with cp, but I got an input-output error. Could this be the filesystem’s fault? And how can I fix this? If you need any additional info about this crash, please do not hesitate to ask.
If it’s running off an SD card then it’s very likely the SD card is broken. It’s better to run a pi off a USB SSD drive. Hope you have backups. Good luck either way.

I’ll second that: every single issue I’ve had with any of the Pis that are around here have all been bad sd cards.
They’re useful if you’re using an OS that doesn’t ever write to them, but as soon as you’re using a full Linux distro or running software that is writing logs or data, they’re going to fail and probably sooner than later and, of course, at the most annoying time possible because it’s a computer and that’s their thing.
OP mentioned a Minecraft server, iirc that can be pretty noisy in the logs.
Oof, and a minecraft server is also constantly writing the world state to disk which will 1000% kill a sd card in a hurry.
tldr Sudden Death card
😹 that’s great
