Creating an VG with LVM fails

Hello,

i want to use LVM, so i did the following steps:

# pvcreate /dev/hde1 /dev/hdg1
pvcreate -- physical volume "/dev/hde1" successfully created
pvcreate -- physical volume "/dev/hdg1" successfully created

and then:

# vgcreate vg_deep /dev/hde1 /dev/hdg1
vgcreate -- no valid physical volumes in command line

And that ist the thing i don't like. Why does it think, that /dev/hde1 and /dev/hdg1 are no valid physical volumes?

/dev/hde and /dev/hdg are on my onboard promise-controller. I've tried kernel 2.4.19-r7 and 2.4.19.-r8 (both Gentoo).
Partitions were made with fdisk, type is 0x8e (LVM).

Any ideas?

It's been sometime since you posted this; if you are still looking for the answer:

https://forums.gentoo.org/viewtopic.php?t=1897&highlight=vgcreate

that thread points out that if you're using devfs, then you need to use the name /dev/ide/host2/bus0/target0/lun0/part1 instead of /dev/hde1, for example.

HTH, I'm on my way to a 230 Gig partition.

I was still looking ... Thanks for your answer

I use devfs and this is what I got by using your answer:

vgcreate -- INFO: using default physical extent size 4 MB
vgcreate -- INFO: maximum logical volume size is 255.99 Gigabyte
vgcreate -- doing automatic backup of volume group "vg_deep"
vgcreate -- volume group "vg_deep" successfully created and activated :-)
