I've got a Raspberry PI, running Raspbian, with latest updates & firmware. I use it as a NAS device, serving out two disks via two USB to SATA adaptors. It runs SAMBA so that Windows computers can easily see the shares.
This has worked well for some time, but recently the disks keep disappearing - the shares remain, but attempts to access the disks gives errors. Even via the console, I cannot access the disks.
They still appear to be mounted, as I can issue a umount without error, but attempting to remount them gives me an error. (Stupidly I didn't note what this error was)
A reboot will cure this 95% of the time, though a few times I've had to power cycle to get everything back. It then runs for a while (few hours - 1 day sometimes 2) before doing it again.
Main question, then : is there a system log file somewhere that might record something to help me work out what's going on?
Thanks
Ian
