Ask away: http://ask.fedoraproject.org I fully admit that I don't understand most of lvm and have considered it a nuisance for my home system. Ten years ago I spent a great deal of time learning about partitioning and became quite familiar with parted and friends. Now at seventy years of age I carefully pick my study projects. LVM was not on the list. It turns out I didn't need lvm lessons. I booted onto my old disk and Fedora 16, fired up gparted, found that this time anaconda had not arbitrarily installed LVM; from parted I added my back up partition with out a hitch. I apologize for disturbing you guys with a non-problem. -- Regards William Case, Fedora 19, Gnome 3.8.4, Evo 3.8.5, Emacs 24x. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
