 Hi,

I'm having a lot of trouble trying to get LVM to pvcreate my 2nd ide disk.
LVM is not on my first IDE disk yet either, but I'll worry about that later.
pvcreate /dev/hdc1 doesn't seem to work.  I've dug through the archives here
and tried a couple of other things as well.  The fdisk and other entries are
below. 

Can someone offer a little direction?
Thanks,
Ron

You have partitioned a partition ! 

You should run fdisk on /dev/hdc rather than /dev/hdc1 and set the partition
type of hdc1 to 8e. Then LVM should recognise it. I am assuming here that hdc1
is the partition you want to use for LVM.

Be careful with fdisk - you can do a lot of damage if you don't know what you
are doing.
