Big-ish SCSI disks

Big-ish SCSI disks

[Greg Johnson]

Hi kernel poeple,

Can anyone out there say for certain that 76GB SCSI disks should
just work with kernel versions 2.2 and/or 2.4? We need to get some
big disk space and have heard reports of problems with disks
bigger than 30GB under linux.

Thanks.

Greg.

I set up a machine at work a few months ago with two Seagate 73GB
Ultra160 drives (model ST173404LW) using the Adaptec AIC-7899 adapter
on board a ServerWorks LE chipset based motherboard.  Everything has
been working fine using the stock RedHat 7.0 2.2.16-22smp kernel.  I
also played with some 2.4.1-ac kernels to try out ReiserFS, and also
had no problems using the disks.

Thanks. Interesting that you mention the Severworks LE chipset. We
have 2 identical machines with the intel STL MOBO wich uses
the Severworks LE. They are both dual PIII 1GHz 1GB mem and ultra
160 drives. I have had nothing but trouble getting RedHat 7.1 beta-1,
7.1 beta-2 and 7.1 release. The OS tended to install ok 
but on beta1, only the up kernel would boot. On beta-2 and release
both up and smp kernels would boot. On neither of the systems
have I managed to build a kernel up or smp, new or same version
as was installed. When I tried to boot the kernel I had built,
the scsi driver would fail to load. This also happen on the Redhat
installed smp kernel in beta-1 and on any of the redhat installed
kernels in either of beta-2 or release when I tried to use disk
striping.

Have you experienced any issues like this?
Have you successfuly built a kernel that booted on these machines?

Regards

Greg.

I'm running stock 2.4.4 on five PCs with these features: ServerWorks
III HE, 2x 933MHz, 4GB RAM, dual-channel sym53c896 (FAST-40 WIDE) SCSI
controller.  One PC has the new 181GB Seagate SCSI drive; another uses a
3ware RAID controller with 4x 40GB IDE (looks like a 160GB SCSI drive).
All is fine with slackware-current.

You might play with "nosmp" and "noapic" kernel params.  When building a
kernel, disable everything including SCSI: work your way up from IDE or
floppy root.  SMP failed on our systems until I dumped the slocket-based
CPUs for Slot 1.  (Still a mystery, that.)

I'm also a user of the machine Scott mentioned.  We're booting it off
of a smaller scsi disk, not the 76G disks.

The disks are partitioned as

75GB 80GB 180GB all work fine...

your issues are:

location of kernel, below 8GB until you have the chance to turn on lba32
in your lilo.conf...

2GB  filesize limit bites people who use large disks more often (well at
least in my app), use reiserfs.
