I don't think you *really* need help.  You got it pretty
well figured out, though I don't know if it's a
vxfs question, as versus comp.ibm.pc.hardware.

If you don't lose any data when that happens, and
if it happens rarely, then you could monitor it
for dramatic increases in frequency or number and
leave it at that.

If people are concerned about it or it's causing
problems with data, then throw some money at it.
Scsi problems hate money.

Very nice.  And don't expect any either :-)
(with good ventilation and no banging on the PC
while it's running, that is...)

  OS can't access it for some reason.

  I though it was.  I think that's what one of
those other tiny fs's is used for, storing bad area 
information.  Then again, I thought it was for 
"badtracks" not bad inodes.

Yes, you just said it.  "All other things, like cable devices are
the same all the time."  Why not try the best scsi cables you can
find.  Use those and see if the problem goes away.  Try a differnt
2940UW.  Want to borrow mine? :)  There's a slight chance that it
could be an intermittent electical failure on the circuit board
of the hard drive somewhere, but that a real longshot.  Try cables,
a different 2940, or patching the OS.

Good Luck,

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

I am a Kerio reseller. Articles here related to Kerio products reflect my honest opinion, but I do have an obvious interest in selling those products also.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
