Well then my idea of making smaller filesystems would break that
then... hmmm I would say that its time to escalate this to Level 2
support :). What do the filesystem kernel people think? I would bring
them in to see if there is something we are missing. Maybe something
in the dealing with that many inodes per file is causing a problem (or
maybe this is just known behaviour for large filesystems.) By the way,
this is a 64 bit OS correct?
Correct, 64 bit OS. I'm going to get some of our FS guys on the horn as
soon as RH is back to work. I think most of them will return on Monday.
