Re: [linux-lvm] Creating a new partition /dev/hda5

I have Fedora Core4 installed on my machine and trying to make mythtv work for

file system. I've done some reading on LVM and come up with following commands
to install the new partition on my machine. I need to have them verified by
experts as I don't want to risk losing any data on my hard.
#pvcreate /dev/hda5
#vgcreate VolGroup00 /dev/hda5
#lvcreate -L50G -name video VolGroup00
#mount /dev/hda5/video
#mount -0 remount,resize /video

Seems your understanding of logical volumes and partitions is a bit confused. First you have a physical disk (/dev/hda). Your "fdisk -l" shows me, that you have divided (partitioned) your disk into two partitions hda1 and hda2, where hda2 contains your LVM data.

So, you won't think about any additional partitions, because there is no space left next to hda1 and hda2. But you want to distribute the disk space within your volume group (named VolGroup00, located within hda2). This has nothing to do with "partitions" any more. Instead you create a "logical volume" (lv) named "video", which is a part of your volume group. Thus its device path becomes "/dev/VolGroup00/video". Before you can mount it, you have to "format" this volume (see mkfs).

However, your "vgdisplay" shows me, that you already used all space of your volume grop (Free PE / Size 1 / 32.00 MB), too. So it seems you already performed some "vgcreate" and "lvcreate". Can you please do a "lvdisplay" or "lvs" to show us the current content of your VolGroup00.

What do you intend using "-O remount,resize"?
