how do I get around the 2TB limit on disk devices?

I've got a 4TB raid array which is showing up as follows:
8    16 2147483647 sdb
8    32 2147483647 sdc
8    48   99470337 sdd
How do I get the kernel to see this as 1 large volume?

That's only a per-volume limit.
Have you tried combining the volumes in RAID0 or LVM?

I've got in working by rebuilding it after disabling auto-carving. Now I've just to find out how to partition 4394437632 sdb since fdisk doesn't work.

Is anyone successfully using a single > 2TB fs?

edit: finally found the info...

you have to use parted & create a GPT partition....

> parted
(parted) mklabel gpt
(parted) mkpart primary 0 3490000
(parted) quit

and you'll have a 3.49TB partition (actually about 3.2TB with reiserfs)
