[linux-lvm] First try, first fail with LVM.

[Roger Eriksson]

I'm new at this list and new with linux lvm.

The story this far. I bought a new hard disk to my file server at home and
decided to reinstall the thing with a newer version of Linux (Red Hat 6.2
before, now Mandrake 9.2). I decided to go with LVM and reiserfs, during the
setup of Mandrake 9.2.

On the server I have two sets of disks. Three 4.6 Gb SCSI disks that I
joined together using LVM and three larger IDE disks that I also joined
together. Everything went well and I started to copy back the files that I
earlier copied to my Window and Linux desktop computers. No problems with
that and since it got late a set the computers to move the files back and
went to bed. The next morning when I checked the damn thing it had rebooted
and reiserfs said that it couldn't find a file system on the IDE set. Now,
after carefully examined the situation I think that it might have something
to do with LVM. It seems like one disk is missing from the vg.

This is the things I've done (from notes on paper, so it's not the real
output from the screen):

> fdisk /dev/hda

And, as I told you, this is my first try with linux lvm. Not sure what to do
now and I rather try to find some answers before I make a mess on my own. I
would like to save the files from the system if possible, but it's nothing
that I can't replace (what I can't replace I have on tapes also).

Any suggestions how to solve this situation?

Thank's for reading.
