Huge Storage Array 17TB partition - xfs/ext3 setup problems

I've got a large storage volume which is a Raid6 giving me 17TB usable. However, I am having significant problems trying to set it up with a filesystem as it's larger than the other two 6TB volumes that I used previously.

I have used the GPT partition type in order to deal with the large block device and created it as one large volume which I want to put either ext3 or xfs on.

Firstly, ext3 would not go beyond 8TB apparently without increasing my block size, which linux doesn't seem to want to do, so I decided to try xfs instead. So I did a basic
Code: [ Select ]
mkfs.xfs /dev/sdb1

to create the filesystem as I'm not so familiar with xfs options like superblock spacing, stride etc..

The command returned suspiciously quickly, and when I try to mount the partition I get the error below:
Code: [ Select ]
mount /dev/sdb1 /mnt/raid
mount: Argument list too long
  1. mount /dev/sdb1 /mnt/raid
  2. mount: Argument list too long

I'm in Knoppix 5.1 at the moment until this is set up and it seems to have detected everything properly so far...

Can anyone give any guidance or feedback on this?

Put that in google. There are a lot of hits on that error message.

Yes I found out that it's an x86 limitation and I've switch to amd64 since it's an opteron machine.

Ext3 still didn't work, but used xfs and now it works.

I'm still trying to figure out this 17TB thing. For my own curiosity, how many hard drive do you have in this thing? I can barely imagine what 17TB would be like, that's a lot of music and movies and pictures.

yeah, I'm so rich I have 17TB in my bedroom....
no it's for work, so nothing interesting on that 17TB. It's about 6-7TB of data from backups and archive from across lots and lots of servers.

It's a 4U 24x1TB disk box, with 20 disks in a Raid6 for your curiosity.

The biggest we have at my office is a single 5U server with one terabyte, and I thought that was bleeding edge.

nah, I had 4TB 2 years ago, 6 TB last year, now it's 17TB this year and I want more, More, MORE!

(I'd also like one of these for home, but I guess I can live with just playing with it at work...)
