filesystem

[Superuser]

I've been having some wierdness with my root filesystem.

1) Last night I suddenely had only 11 inodes according to df. I really had
   about 10,000.  When I fsck'd, it said the problem was fixed, but it still
   only showed 11 inodes.  After reading some books, I tried fsck and as soon
   as it was done I powered down.  I restarted the computer, cleaned the
   power off mess and I had my 10000 inodes back - everything looked fine.

2) This afternoon, after working fine this morning, when I use df the root
   filesystem isn't reported - only the /dev/u.  But if I use
   df /dev/root  then it reports it ok, but it wont report
   df /dev/rroot - which is normal??

What is afoot here  -  I'm paranoid some evil presence is at work in the
filesystem.

Something that is probably relevant --> I have an intermittent bad cylinder
on the hard drive

Anybody want to take a stab at this one.

I'm running SCO Unix 3.2.1 (Open Desktop ,but this happens in straight unix)
Mylex 20 Mhz w/ 80387  
8 megs memory
Miniscience HH1090   --> /dev/root
Miniscribe 3085      --> /dev/u
Western Digital 1006
