Re: [Rocks-Discuss]Huge 1.2TB partition

[Joe Landman <landman@scalableinformatics.com>]

Hi Stas:

  There is a bug in 2.4 kernels with SCSI  that limits you to 1 TB or 
less.  The folks at 3ware have a patch for it (it is fixing a signed int 
to be an unsigned int in sd.c).  Without this patch, you are going to 
have trouble making a single large volume.  You could create 2 volumes 
and LVM or MD them together.  This would be hard to do with the number 
of disks you have as a RAID5.

  What is best is usually dictated by your use case.  For large storage 
purposes, one volume might be better.
