/home randomly fails
Not sure where to check logs for this, but here's what's happening.
It'll boot up fine, but at random after a few days /home becomes unusable.
ls brings up an i/o error.
I try to unmount it, but it's busy, so I throw -fl in, and it will.
I try to remount it on /testing to see if that helps any, and it mounts, but still isn't usable again (same i/o error). I have to use -fl to unmount it again.
Reboot fixes this issue.
