Well, I upgraded to 12.04 and of course there's no change since the LSI SAS1068E controller doesn't support drives larger than 2 TB. Sigh.
Can anyone recommend a 2- or 4-port PCIe non-RAID controller that works under Linux, supports large drives and is affordable?

It looks like the kernel is not recognizing the size correctly.
So... Upgrade to Ubuntu Precise 12.04 LTS?

Subject: [RndTbl] Linux 4K drive formatting
So... I picked up my lovely new WD Red 3 TB drives today and installed them in my home server.
Now what? :-) Specifically, I'm running Ubuntu Server 10.04 LTS (2.6.32-45-server #102-Ubuntu SMP Wed Jan 2 22:53:00 UTC 2013 x86_64 GNU/Linux), and I'm wondering if I should upgrade to Precise before I do anything with the drives, or use them as-is. I know I should align the partitions at (at least) 4 KB boundaries, and 10.04 by default uses 1 MB alignment, so I should be okay there.
Should I worry that the drive reports
fdisk -l /dev/sdc
Disk /dev/sdc: 2199.0 GB, 2199023254528 bytes
255 heads, 63 sectors/track, 267349 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
...instead of 3 TB, and thinks the sector and I/O size is 512 bytes?
Advice, please!
Kevin
