XFS & the RedHat Installer

["Bob Perper" <bperper@xxxxxxxxxxxxxxxxx>]

Hi,
   My name is Bob Perper and I'm a developer of the backup product 
UPSTREAM.  When I used the "XFS for Red Hat Linux 7.1 Installer" to upgrade 
my RedHat 7.0 system to 7.1, it all worked well.  However, when I tried:
        mkfs -t xfs /dev/hdb1
   It reported the error:
        mkfs.xfs: No such file or directory.
   There's also no fsck.xfs in /sbin.
   However, the xfs daemon is running.
   I've been somewhat afraid to try to install any RPM's since it seems to 
be partially installed now.  Where should I go from here?
   Thanks,

        Bob Perper
