[CentOS-devel] xfs volume can not be mounted with uuid or label, only scsi device name /dev/sdb

kernel 2.6.18-92.1.10.el5.centos.plus
kmod-xfs-0.4-1.2.6.18_92.1.10.el5.centos.plus
xfsdump-2.2.46-1.el5.centos
xfsprogs-2.9.4-1.el5.centos

the kernel comes back with device not found when i tried label= and uuid=, after changing the fs from ext3 to xfs. with ext3 all 3 works fine, but with xfs only the device name is accepted. any advice is appreciated.
