But the above makes it seem like you simply wish to transport snapshots. Why not use something as straightforward as dd for this rather than RAID1? RAID1 tools (mdadm, drbd, etc.) have the benefit of keeping volumes in sync over time. But the above process describes a synchronization over a single instant (the instant of the snapshot being taken). So why bother with the extra work/capability/ complexity? I'm also puzzled by something you wrote in your very first message on this thread: "the hard-linked filesystems on FILER-B require full filesystem cloning with block-level tools rather than file-level copying or sync'ing." Why? rsync -H handles cloning of hard links (though at a performance cost). - Andrew _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
