    Totally confused with LVM on fc7

    I tried searching this forum, but have found nothing that helps. So here goes.
    I installed Fedora FC7 on my multi-operating system PC which uses System Commander to boot between Win2k, Fedora, DOS and OS/2. Prior to Fedora, I had installed Redhat 6,7 and 9 and all was well.

    When I decided to install FC7 I went ahead and installed it with the default LVM, although I didn't understand exactly why I did this, except that it was the default. (Yes, I know... )

    My Fedora partitions are:
    /dev/sda9 for the boot partition (/boot) - 94 MB - ext2
    /dev/sda10 for the Swap - 1 GB
    /dev/sda11 for Mount Point / - 64 GB - ext3

    During the boot sequence, I see that LVM is loaded. The problem seems to be that I when I try to see what logical volumes I have, I get the message:

    [root@dad ~]# lvdisplay
    File descriptor 5 left open
    File descriptor 7 left open
    No volume groups found

    OK, I haven't defined any logical volume groups and I don't know how, or why I would want to. I'm just now trying to get rid of LVM, so I could have a file system that I understand, but previous responses to posts have me totally confused.

    Very simply, I want to back up what I currently have in /boot and /, then wipe the partitions clean and reinstall fc7 and restore all my files. Can someone refer me to a Howto or Faq which could describe a step by step process to do this?

    Eternal thanks if someone can do this.

    Hello tvoltagg,

    According to that, maybe you didn't choose an LVM partition layout for Fedora. In fact, I like it. Why get rid of it if it's working?

    P.S.: I read your other thread about the size of Acronis backups of ext3 partitions. I guess that is what led you here. When people start saying things like "LVM underneath ext3", I know I'm in over my head with your LVM thing. I hate it, don't use it anymore, didn't use it long enough to learn the ways to screw it up. I should retreat from here because of that. But I do remember this: When I backup an ext3 partition with Acronis, the TIB file is big. Really big. Nearly as big as the partition. And I don't use LVM.
