Maximum Volume size for XFS on Linux

[Jeff Cooper <jcooper@npc.census.gov>]

Hi,

I have a large Linux SAN with 8 - 1.8TB volumes
for a large data capture operation.

I am able to format the drives with mkfs.xfs,
and until a certain point, around 800GB, things
are fine.  At this point however, the file system
freezes, and we are unable to create any more files
on the volume.  

I am running kernel 2.4.18 with the XFS1.1 patch.

The image files on the volume are all between 20-40K.
We had hoped to put over 10,000,000 images per volume,
spread evenly over 80 root directories, with 400 sub 
directories.  Each low level directory would hold approx 
1300 images.

Can this be achieved with XFS?  As long as I stayed
under the 2TB block device limit, I thought things
would be fine.

Any help or ideas would be appreciated.

Thank you,
