Problems with SCSI Array with LUN larger than 1 TB
We are seeing the following problem with a scsi array attached via an
Adapted 29160 SCSI card. The array has a single LUN of 1.3 TB.
Is there a limit to the filesystem size in the 2.4.21-193-smp kernel of a
terabyte or less ?
Is this a problem with the card, or a kernel issue ?

Either with the card or with the driver. The kernel has no TB limit. I would suggest you talk to Adaptec, they maintain the driver. -Andi

Hi, there is a known issue with Yast2, which cannot manage Partitions larger than 1TB. After lots of problems with grub not booting, I have split our scsi-attached RAID into 1TB pieces and intalled LILO.

parted had such a bug (and is used by YaST2) - and that one will be fixed with 9.1.

Seems like some of the problems are with the Adaptec driver included with SUSE. Here is what we have found in our Singapore office...
Mainly, we had stick with a RedHat 8 installation on the opteron server. This is because SuSE 9 with the 2.4.21-193 kernel has a very new Adaptec driver whic has the following warning in the >> kernel's log message,
kernel: scsi0:A:0:0: DV failed to configure device. Please file a bug report against this driver.
This apparently is because the Adaptec driver on the 2.4.21-193 driver has this Domain Validation (DV) SCSI feature introduced in their newer driver. The Brownie box apparently has no such feature and is thus unconfigurable by the Adaptec HBA.
Also, we have tried creating filesystems on a RAID array with a single LUN
at 1.4 TB. We have tried both the Qlogic 2300 and LSI FiberChannel HBAs,
but when we create a filesystem on this LUN, (either ext3 or xfs), once we
cross the 1 TB boundary, the system starts receiving SCSI errors...

The HBA makes no difference, and things seem to work fine on RedHat 8....
Any suggestions ?
