james, thank you so much for your help. indeed, the problem is that /etc/blkid/blkid.tab still has the old ext3 entry.
i changed TYPE to xfs and updated the uuid for /dev/sdb, and now it mounts fine with UUID. since i prefer UUID anyway, i did not test label, but assume it was the same issue.
yes, we do use the entire device, which never had problems with other fs types, which mount seem to update blkid.tab automatically. still not sure why it did not do so for xfs, but as long as it works, i am happy.
You get the same issue with ext3 - if an entry doesn't exist in /etc/blkid/blkid.tab, then mount by LABEL/UUID will not work for file systems on the whole disk - unless you first mount the file system by device to create the blkid.tab entry
