You're probably already aware, given that you mentioned 'dm', but this method means the mirroring is abstracted out from LVM and handled by the dedicated processes. Sorry that wasn't a great help, but thought I'd share. I'm actually considering the best approach myself in preparation for rebuilding my file-server, and I found (oddly enough) a very informative Slashdot.org comment thread on the general subject: http://ask.slashdot.org/comments.pl?sid=169386&cid=14117414 Good luck! -Barnaby John Smith wrote: > Hi. > > > I was wondering if current releases of LVM2 included mirroring support > in the actual logical volume manager itself ('native' mirroring > support), without the need for any other external mirroring solutions > (like for example 'dm') ? > > > > Sincerely, > > > John Smith. > > _______________________________________________ > 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/ >
