So, I'd think that I could do the following and it'd just work:lvcreate -L 50G -s -n guest-backup /dev/vg1/guest-disk mount -t ext3 -o rw /dev/vg1/guest-backup /mnt/snapshot cp /mnt/backup/guest/etc/fstab /mnt/snapshot/etc/fstab.restore umount /mnt/snapshot/ lvremove -f /dev/vg1/guest-backupDude, it doesn't work that way.The way I see it, you're writing data to /dev/vg1/guest-backup, but then you REMOVE the LV afterwards. And you expect it to show up on /dev/vg1/guest-disk? Alternatively, you can completely shut down the guest and mount both partitions and copy things to the old guest partition, but I don't think you want to do that. By the way, why are you using partition based LVM images, rather than disk based LVM images? _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
