I've got a PI that has been quite happily working away since the spring. I'm not overly taxing it at the moment, but that should change.
It sends me an email once a day (triggered by cron) with some information it has gathered. Yesterday I didn't get the email, but didn't have time to investigate. Today, I've not had an email, so I decided to have a look.
The Pi is plugged into my TV, but to keep things tidy, I unplug the USB hub, so the keyboard and mouse are not usually attached. I reconnected the hub/keyboard/mouse, and then turned the TV on. I got the Pi desktop, but it wouldn't respond the mouse (pointer stayed mid screen) or keyboard, so I turned the power off to reboot.
Upon rebooting, it got so far through the sequence, then told me that there was a file system problem, and asked me to run fsck and reboot, which I did.
Fsck duly reported problems (which I didn't get a note of), giving me a large number of errors (numbers, so block numbers I assume), and then asked me if I want to fix, I typed y and return. From this point on, it had a bad habit of continuing to print the y character on the screen until I pressed return again.
Once fsck had finished, I ran shutdown -r now (the w character appeared across the screen many times). It started to reboot, and I got about a screen full of messages (which didn't seem to give any errors). Once the first screen full had appeared, it quickly cleared the screen, and all I got after that was a blank screen with a flashing cursor top left. Power cycling leads to a repeat of the above.
Any suggestions ?
TIA
