Invalid argument when trying to set the blocksize.

[Austin Gonyou <austin@xxxxxxxxxxxxxxx>]

I try to perform the following:

mkfs.xfs -b size=8192 /dev/data/datavol1

The fs is made on the volume, but I get the following message:

mkfs.xfs: warning - cannot set blocksize on block device 
/dev/data/datavol1: Invalid argument


I'm using LVM 1.1rc2 tools, and have a 2.4.19-pre9-aa2 kernel. 

Is this another one of those ioctl() things that's depricated or is it
something else. TIA

But if you meet it promptly and without flinching, you will 
reduce the danger by half."
