Resize the LV in dom0: root@dom0# lvresize -L +5G /dev/VolGroup00/xendisk ...boot the domU. Run fdisk or some other partitioning utility in the domU. Resize the partition there: root@domU# fdisk /dev/xvda ...reboot the domU, since it'll still be in use. When it comes back, it should see the new partition table. Now (assuming the PV for the domU volgroup is /dev/xvda2): root@domU# pvresize /dev/xvda2 ...now the volgroup in the domU should see the new PE's. Resize the LV's and extend the filesystem in the domU as you normally would. I've done this several times and it's worked fine for me. There should be no reason to import the VG into the dom0, unless you want to shrink the domU root partition or something. -- Jeff Layton <jlayton@xxxxxxxxxx> -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
