    Well, I've reformatted since I had that problem.

    I think the reason for these errors was (as someone pointed out on the lvm
    mailing list) that I had mounted the partitions that I trying to put into
    the volume group, and was running the system off filesystems mounted on
    them. So it is not surprising that there were problems.

    I should figure out how to set a reply to header in Pine.

    Thanks for replying.
