No moving necessary. They are both on the Volume Group, space doesn't have to be contiguous, etc, etc.... I would suggest that when reducing you should use the "same numbers" for both resize2fs and lvreduce. Don't use an absolute number for one and a relative number for the other. As an alternative, that might be easier, why not install "system-config-lvm"? It presents a graphical view of shrinking and enlarging..... --Rob -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
