[linux-lvm] Hello. About a bug in lvm2

[Sebastian Hyrwall]

Hey.

Im not sure but i may have found a bug in the lvm2 userspace-tools. Im 
using gentoo right now and right now
lvm2 cant "see" some harddrives.

I first discovered the problem when i changed from 2.4 -> 2.6. In 2.6 it 
didnt find all my discs. Later on i saw that when i did
"pvcreate /dev/hdd1" (tried the devfs-link also /dev/ide/....) it 
reported that the device couldnt be found.
There isnt anything wrong with the hd or anything. It shows up in 
cfdisk/fdisk and i can use it as a normal hd (not in an lvm).

This occurs for 2 of my disks. hde and hdd. I cant find any difference 
between them and the other drives. They are all the same size.


Unfortunently i cant provide any more information because i didnt think 
about mailing this to you until after i went back to 2.4.


Sincerely, Sebastian Hyrwall

Do you have configured properly your kernel for lvm support?
Do you have lvm2 package(s)?
Did you setup properly your /etc/lvm/lvm.conf?

Run vgscan -vvv, grep for lines mentioning the 'missing'
devices, and see what reasons it gives for ignoring them.
