I've noticed some annoying problems with one of my new systems..
The disk space is located on a Compaq Smart Array 3200 controller.
The controller takes care of everything regarding RAID, so that part doesn't
load the Linux system.
The system loads the driver cpqarray in initrd, everything seems fine so
far.
The problem is that when the file system gets a load, for example if I copy
large files to the volume, it takes forever to complete and the system seems
hanged. After 10-90 seconds, it continues its work. If I have one window
open with 'top', that too freezes during this period.
Since it's SuSE SLES9, I formatted everything with reiserfs, my thinking
wass that this may be the problem, but then I tried with XFS as well, just
the same problem.. I'm just guessing.. If someone can clear things up, I'd
be grateful..
Nothing gets written in /var/log/messages about any problem, I don't have a
clue on where to begin looking. The arrays (disks and controller) are in
fine condition, if I test copying, accessing and other in Windows 2000,
everything is blazingly fast and trouble free, so the problem must be in the
Linux system somewhere, I just don't have a clue to WHERE.
