Re: LVM and XFS cannot set blocksize on block device

[Rene Salmon <rsalmon@xxxxxxxxxx>]

Hi,

Thanks for the reply. The "-s size=4096" helped I was able to create
the file system, then mount it and use it.  I did however get a warning 
still about "cannot set blocksize on block device".  Everything seems to 
be working but I am a bit worried about the warning message.  Following 
is the message.  Any ideas if it is safe to ignore this or any way to 
get rid of it?



helix-priv:~ # mkfs.xfs -s size=4096 -f /dev/vg_u00/lv_u00
mkfs.xfs: warning - cannot set blocksize on block device
