Hi LVM-specialists,
I'm new here the Linux-LVM-array. This means I was downloading all
needed software+patches, compiled successfull and also installed without
erors on my IBM-Thinkpad (300 MHz PII, 128 MB RAM, 8GByte HD).
I have all my LINUX-stuff on several extended partitions.
Now at first some generally questions (I don't found an answer for this
in the docu):
Is it possible to create a PV on a extended partion or do I need only
primary partions ?
I think pvcreate writes something at the top of the physical volume (
whole PV or partion).
Do that works well with other OS-formated parts of the same hdisk ?
If the first question is no, forget the rest of this mail!
If it should works please help. Here are all infos related to my
problem:

Great.

You can use primary _and_ extended partitions.

Yes, it does.
If you use a partition with pvcreate, you have to set the partition identifier
to 0xfe with fdisk before.
pvcreate checks for this partition identifier to avoid to overwrite _non_
LVM partitions by accident 8*)
