I have just built my raid 6 array and get the following error when trying to create a ext4 file system

root@nas:~# mkfs.ext4 /dev/sda1
mke2fs 1.41.11 (14-Mar-2010)
mkfs.ext4: Size of device /dev/sda1 too big to be expressed in 32 bits
using a blocksize of 4096.
root@nas:~#

What recommendations do people have for a file system of this size?
 
xfs if you want to stay linux. zfs if you want to setup a vm/bsd/solaris. ext4 can't create any fs over 16tb.
 
Ext4 works, you just need a newer version on mkfs.ext4 and a newish kernel.
XFS also works.

Yes, ext4 will support greater than 16TB filesystems. But none of the ext4 tools currently do. So with ext4 you are ok as long as nothing goes wrong...
 
The tools have supported it for 3-5 months now.
I switched from XFS to EXT4 60TB no problems.
