CentOS - May 2009 - fs for > 16 TiB partition

Hi,
What would you recommend as an FS for an partition greater than 16 TiB?
This is for an production server (that is, no ext4 recommendations
please :) )
What experiences did you had with your preferred FS ? (good and not so
good points)

Thank you,
Adrian

I personally would go XFS. Made the very best experiences of any 
filesystems I ever used (well, it was XFS on IRIX).

Does anybody actually run such a thing on Linux?

How long does a FSCK take once it's 80% populated?
How much RAM does that need?

The FSCK on my Virtuozzo-partition takes long enough - and it's only 500
GB or so.

We've got a 110 TB xfs system in production based on a logical volume
striped over 9 boxes of SATA disk, works like a charm with great
throughput as we stripe over 3 controllers :-)

Only whoopsie in 18+ months was when we recently added 3 more disk
boxes and I grew the filesystem. First attempt xfs_grow only added a
fraction of the available space. Second attempt gave a kernel panic.
Reboot and everything was fine with all space available.

Lesson learned: don't use xfs_grow unless you're in the general
vicinity of the server ;-)

regards,
