I have an ARM box which was working fine until it went to site. It's running Debian and I only have access to it via SSH (although at the moment I have someone on site who can force it to reboot).
Twice today I've received the error "kernel:journal commit I/O error" to my SSH terminal, after which point the root filesystem gets unmounted and I can't do anything even though the unit is still "up". Eg: $ ls -bash: /bin/ls: No such file or directory
Any ideas what would be causing this? It's an expensive SD card in these units (not a cheap no-brand)
This is the unit in case anyone is interested, it's running Debian 6: http://www.newit.co.uk/shop/proddetail.php?prod=DreamPlug_N
I'd also be interested to know if there's anything I can do down an SSH connection to force it to reboot, given the lack of access to the filesystem to even run "sudo" never mind "reboot". I'm guessing that sending Alt-Ctrl-Del or Alt-SysRq-B via SSH are out...
