I'm pretty sure I have done a full fsck, but not positive, so I will try one tomorrow. The system is in a location which is unmanned today due to the holiday, and a full fsck kind of needs either a human or remote console. I have tried both with and without snapshots, so those don't seem to be the problem. In any case, I'll know more tomorrow. -- R.
