If the question is about segment type, raid0 and raid1 use the md driver code (same kernel code the mdadm raid uses, but is managed with LVM metadata and user space tools). And striped and mirror use an internal implementation, although I'm not sure if this is internal to LVM or device-mapper, and I think are considered legacy at this point. 'man 7 lvmraid' doesn't directly answer your question but contains quite a lot of information about lvmraid. It does explicitly say to use raid1 over mirror segment type. It doesn't say that about raid0 vs stripe segment type, maybe the two implementations aren't all that different but anyway I would use raid0. -- Chris Murphy _______________________________________________ linux-lvm mailing list [email protected] https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
