How to diagnose errors when mounting root filesystem?
So I am remotely accessing an embedded Linux device which boots from a flash memory card. That card is formatted using ext2 and mounted with errors=remount-ro.
My problem is this: sometimes, the filesystem of this device boots as read-only, and I've even seen it go into read-only mode while running, without a reboot. I think this also has something to do with fairly frequent system crashes I am also experiencing. I assume that some error is triggering this, but I can't find any log of such an error. That stands to reason, since it would be hard to log errors to a read-only filesystem, but I still want to diagnose this somehow.
