I have some additional information that hopefully someone will be
familiar with and provide some assistance.
The kernel I am using 2.4.18-6 was created using devfs. However, when I
am trying to create a physical volume on /dev/hdb devfs is not active.
My /proc/partitions is as follows:
22 0 15972 hdc
3 0 20066251 ide/host0/bus0/target0/lun0/disc
3 1 313267 ide/host0/bus0/target0/lun0/part1
3 2 265072 ide/host0/bus0/target0/lun0/part2
3 3 1 ide/host0/bus0/target0/lun0/part3
3 5 3076416 ide/host0/bus0/target0/lun0/part5
3 64 20066251 ide/host0/bus0/target1/lun0/disc
is it the case that pvcreate is interpreting "disc" as a partition
because it does not detect a traditional "hdb" and therefore cannot
create the physical volume? is devfs required to be active for pvcreate
to locate the disc according to its naming convention?
