Will, you could have mentioned:
1. a command to set the label ?
2. whether an lvm label like LogVol01 or LogVolhome is the same as the
label you are mentioning ?
Consider it either good or bad that a long time redhat/fedora user
does not know such a command - it gets set by the installer - for
actual partitions, but not? for LVM logical volumes ?
After much searching "label lvm partition" etc in google with little
result, I stumbled across the mkfs.ext3 parameter -L volume-label, but
decided that would actually format the partition.
tune2fs -L yourlabel
