The maximum supported file system size under Linux 2.4 is just under 1Tb.
The scsi layer gets slightly confused a bit earlier with its printk messages

Is there any particular (that is, technical) reason for this? A few months
ago I hit this problem while building a RAID system for our group. We wanted
to do software RAID-0 over three hardware RAID-5 arrays (2 by 375G and one
525G) and the kernel (2.4.6) had a hissy fit.
Given the relatively low cost of disk space ($5000/terabyte and on up, see
http://staff.sdsc.edu/its/terafile/), is this something that will be supported
in the future?
If you point me in the right direction I'd be willing to look at this issue.
Thanks
-Eric

2.5 Im sure

There is a patch to allow 64-bit block devices - Ben LaHaise or Jens Axbow
put it out about 2 months ago. I believe it fixes the SCSI midlayer,
and a limited number of drivers. This is probably a good starting point
(you may need to update the particular SCSI driver you are using).
Cheers, Andreas
