different behaviour between XFS and ext3

[Blair Barnett <bbarnett@xxxxxxxxxx>]

Hi,

I have a simple shell script that writes numbers to a file and every 10
numbers does a sync and after 40 does a reboot. I've attached the script
to this email.

If the file is written to an EXT3 filesystem, then file contains the
numbers 1-40. However, if the file is written to an XFS 1.1,1.2, or 1.3
filesystem, then file contains the numbers 1-10.

Can someone tell me if this is a feature of XFS or a bug?

Thanks,

Blair
