I've run into this, too. You have to umount the filesystem before you make the snapshot, eg: umount /home lvcreate -L 1G -n homebak /dev/vg/home mount /home With XFS (which I haven't tested), you can run xfs-freeze to commit the journal without umount, but with ext3 the only way to commit the journal is to umount the filesystem... -- David Johnston <david@littlebald.com> Little Bald Consulting, LLC _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
