I have built a system a couple of 3Ware 12 port SATA RAID controllers (model 9500s-12MI). I have attached 12 Hitachi 400 GB disks each of the 3Ware controller and have built a level 5 RAID through the 3Ware software. When the system is booted it sees the devices as scsi disks, /dev/sdb and /dev/sdc. The problems I have come when I define a partition table for the disks. I can able to define a file system larger than 2GB using reiserfs. I can not create two partitions of 2TB each, e.g. sdb1 and sdb2. I have looked on the web and seen that the limit for reiserfs is 16TB, so I know it is something I have overlooked, or have made a mistake with (more likely). I have searched for a 'how to' to walk me through this, but with no success. System: Motherboard : Tyan Thunder i7520/S5360 CPU : 2 x 2.8 GHz Xeon Memory : 2 GB OS : SuSE 9.2 64-bit (still waiting for 9.3) Kernel : 2.6.8-24.14-smp If anyone has any suggestions they will be greatly appreciated.

I have found a solution. You need to use 'parted' to create the partition before using mkreiserfs to format it. I have now 2 4 TB partitions. Sorry for bothering the list. Peter M. Bloomfield
Peter, Please keep the list updated with your progress. I have not heard any success stories with multi-TB filesystems yet. The PATA controllers from 3ware I have used have a 1TB limit per RAID unit (I know it is possible, but I have not used LVM etc. to build a bigger virtual drive.) FYI: The 1 TB server I have now is too small. :( I have a very tall tower that has 15 drive slots, I would love to build a multi-TB fileserver out of that. :) Also, very curious about performance, etc. Greg -- Greg Freemyer On 5/9/05, Peter M.

Peter,

Untrue. I have 6 servers in my dc that have 12 drives connected to these SATA 3ware controllers. They have 1 root, 1 parity and a 10 drive single partition (1.8T). I had issues with 9.2 and reiserfsck on these but with 9.3 this issue went away. It works just fine and isn't limited to 1TB per RAID group.. -Ben -- "There is no need to teach that stars can fall out of the sky and land on a flat Earth in order to defend religious faith."

Oddly enough Peter, it's the things like this that others benefit from, so it's not a bother. You're experience will be archived on the list. I popped a solved on the thread, to make the solution easier to find.

;O Well, you can send me that box, I'll work it out somehow! Damn man, all my disk space put together doesn't equal that big...... And it's a Xeon!!!! Can I ask where and how you got this thing? How much did it cost? another thing, what are you using to partition? Cfdisk could maybe do it or the YAST partition tool whatever it uses.
If anyone has any suggestions they will be greatly appreciated.
