RPi 3 - Changes don't 'stick'

Postby ngoonee » Wed Apr 20, 2016 8:34 pm

I installed the RPi 2 image on RPi 3 (as recommended by the webpage). Fairly simple, do fdisk, bsdtar, copy boot out to the boot partition. It boots up fine.

None of my changes stick past a shutdown/reboot. Installing packages or editing fstab.

So I'd do (for example) pacman -Syu, and everything would download and install. Or I can pacman -S sudo and set it up, it works, so it is installing at some point.

However after a systemctl reboot (or poweroff) it doesn't work anymore.

Perhaps related, after every reboot or poweroff ssh warns me that 'REMOTE HOST IDENTIFICATION HAS CHANGED'.

Also, I tried running 'sync' just before reboot/poweroff, as well as leaving it for a while (thinking that the systemd SD card saving tricks mentioned here[1] may be to blame). No change.

Could it be:-
1. Power supply problems?
2. Bad micro-SD card?
3. Something else?

I might be inclined to suspect the card.
Initial diags would be to trawl journalctl. Almost sounds like the ext4 filesystem has (re-)mounted read-only. But a reboot should force fsck if needed these days. Doesn't fix dead card though - I also recently just got into ARM on a Pi3, and after setting everything up, I decided to check the second 32G card I bought. It is now in the bin - brand new.

Thanks, indeed another card worked just fine. Man, this card lasted me all of 2 days.... it was a Noobs card too, not some cheap quarter-priced online purchase (that's what I'm currently using which works).

Then again, I have no idea where Noobs sources their cards...
