We have a 3B2/400 running SystemV Revision 3.0.  We have always been
tight of i-nodes, running about 1500 free i-nodes in the /usr
partition (which also includes /usr/spool).  A couple of times we have
run out of i-nodes and have had to go through the partition deleting stuff.
We also have repartitioned the disks a couple of times.

This week we had a power failure.  In bringing up the system after the
failure, fsck was run and various magical fixes were applied to the
system.  After we were up, I ran df and noticed that the number of free
i-nodes was now 7400!  I assumed that fsck had deleted some files or
something, so I went back to our latest backup (about 5 days ago).  The
only files that I could see that were deleted were news article that would
have expired normally in that time.

Now, I'm not complaining -- who couldn't use an "extra" 5900 i-nodes, but
I am puzzled as to where they were found  -- or worse, what we may have
lost to get them.  By the way, the filesystem has 18656 i-nodes to start
with, so 5900 extra is a significant amount.
