I've had a OMV system on my Odroid hC1 running armbian stretch for about a year or so with no problems. I've done updates every now and then without hickups. But now about a week after the last updates the HC1 wont boot again, it just died and restart won't work. The blue indicator is always lit which indicates that the kernel isn't running. It isn't visible on the LAN and I can't connect via ssh.
I've confirmed that the HC1 is OK as it can run other configuration i have on a different SD card. I've checked the SD card for bad sectors, but it seems OK. I copied the SD card to another and that won't work either.
as a HC1 is headless I don't know how to troubleshoot. The problem is I have a few dockers running on this HC1and I would like them to work again. I guess most important is my Nextcloud docker as it contains my household's photo collection. I know i probably can start from scratch but if there is a way to save this system I'd like to try that.
so what are my options? Bare in mind that I am pretty novice on linux.
