LVM and XFS cannot set blocksize on block device

[Rene Salmon <rsalmon@xxxxxxxxxx>]

Hi,


I am trying to create an xfs file system on and LVM logical volume.
the actual physical drive has blocks or sectors of 4096.

when I try to make the xfs file system on top of LVM I get this message:

helix-priv:~ # mkfs.xfs -f /dev/vg_u00/lv_u00
mkfs.xfs: warning - cannot set blocksize on block device 
/dev/vg_u00/lv_u00: Invalid argument
Warning: the data subvolume sector size 512 is less than the sector size
reported by the device (4096).

helix-priv:~ #





any ideas?

Thanks
