I'm guessing this behavior is OK but just wanted to be sure.  I was
playing around with the undo utility and tried:

ocotillo# undo -i /data2/*

What's worrisome is the messages this generated in /var/messages:

I'm running 2.6.2 with the most recent updates and this is on a 2 TB
volume that is only about 20% full.  When the recent filesystem
corruption thing came up, I performed the recommended checks and they
reported that the filesystem was clean.
