I have a Pi 5 with a GeeekPi M.2 HAT and a Crucial P3 Plus 2TB M.2 card, powered from a Raspberry Pi 27W USB-C power supply. I was able to register the SSD's serial number on Crucial's web site, so I believe it to be genuine. I am running Raspberry Pi OS Lite (64 bit), fully up to date. I also have an externally powered 4TB HDD formatted for BTRFS, which does not seem to be causing problems. The system is running headless (i.e. no monitor, keyboard or mouse), connected by wired Ethernet. The purpose of the system is to act as a Time Machine server for backing up Macs, which means that it is running Samba (only offering a share on the external disk, not the M.2 boot disk) and Avahi for network discovery.
The issue showed itself after a few days running without problems. Backups would fail, and although SSHD was clearly running, connections were refused. I booted off a uSD card, and tracked down the problem to the boot M.2 drive going offline periodically. Since this is Linux, processes like SSHD carried on running, but could not read or write, hence the problem with logging in.
Here's the problem: the logging journal depends on having that disk, so I'm not getting any log messages to check. At the moment I can't work out whether to blame the power supply, the RPi 5, the HAT, or the M.2 SSD.
Any ideas how to proceed?
