[root@bntly ~]# vgcreate VolGroup02/LogVol00 /dev/sda1 /dev/sdb1
New volume group name "VolGroup02/LogVol00" is invalid
[root@bntly ~]# vgcreate VolGroup02 /dev/sda1 /dev/sdb1
Volume group "VolGroup02" successfully created

#k. i used lvmgui-0.4 to do the pvcreate`tion. i wiped both disks with 
fdisk, then used lvmgui #with pvcreate. i then used vgcreate VolGroup2 
/dev/sda1 /dev/sdb1, and i'm thinking i'm stuck #now. i'm sure all i 
have to do now is make entries, like lvcreate? so i did, and heres what 
i #got:

[root@bntly ~]# vgdisplay VolGroup02

#i'm thinking this is pretty cool now, and so i 'm (blabbing) making an 
entry! but i'm confused #now, because the guy says something about 
making a special entry, and i'm not sure if that is a #new name or my 
VolGroup02 name, or if it should LogVol00?

To create a 1500MB linear LV named 'testlv' and its block device special 
'/dev/testvg/testlv':

*# lvcreate -L1500 -ntestlv testvg*
