using xfsdump with 'file device'

[Christoph Lukas <christoph.lukas@xxxxxxx>]

Hi,

we would like to use xfsdump to backup one of our xfs filesystems onto 
another hard disk. Therefore I tried:

xfsdump -l0 -F -f /mnt/backupfile /dev/sda3

Although we are running kernel 2.4.3 and glibc _with_ >2GB support (tried 
with 'dd if=/dev/null of=/mnt/testfile' ) xfsdump exits after dumping 2GB 
with:

xfsdump: creating dump session media file 0 (media 0, file 0)
xfsdump: dumping ino map
xfsdump: dumping directories
xfsdump: dumping non-directory files
File size limit exceeded

is there any possibility to exceed this limit (compile time option?) or any 
easy alternative to work with multiple 2GB files (like the ordinary dump 
does)?

Thanks,
Christoph
