[linux-lvm] lvm and software raid1



Hi!
This is my first contact with LVM, so maybe i am doing something
wrong, however this are my problems:

I try to install LVM on /dev/md1:

# cat /proc/mdstat 
md1 : active raid1 sdb7[1] sda7[0]
      15411072 blocks [2/2] [UU]

Kernel is vanilla 2.4.5, distribution debian sid of today.

md1 is about 15GB, but when i run pvcreate on it, it uses only 1.8 GB:

# pvcreate -ff /dev/md1
pvcreate -- WARNING: forcing physical volume creation on "/dev/md1"
pvcreate -- physical volume "/dev/md1" successfully created

# pvdisplay /dev/md1
pvdisplay -- "/dev/md1" is a new physical volume of 1.86 GB

Any hints?

Thanks, Ramin
