[linux-lvm] pvcreate problem

i just installed a fresh RH linux 7.3, with LVM 1, or whatever comes in
the RH distribution.

ihe first thing i'm trying to do is pvcreate on my big RAID 5 array, which
is /dev/sdb:

[root at discord root]# pvcreate /dev/sdb
pvcreate -- ERROR: can't initialize physical volume "/dev/sdb" of volume
group "homevg" without -ff

but there is no volume group homevg:

[root at discord root]# vgdisplay homevg
vgdisplay -- volume group "homevg" not found

i am able to fdisk a partition onto /dev/sdb, and then do a pvcreate on
that partition, but i want to do a pvcreate on the whole free volume, no
partitions! i may have made a typo before, by trying to do a pvcreate
/dev/sdb, i instead did a vgcreate /dev/sdb. and them i might have tried
some other crap cause it was freeking out. i rebooted so i can see the
history, unless lvm keeps some kind of log file? i couldnt find one.

i rebooted, etc. id prefer not to have to reinstall everything. how do i
fix this problem?

any ideas?

thanks in advance!
