I haven't found any FS which would do block-level replication relying not on dumb copies, but on RAID5/6-like parity algorith= ms for fault-tolerance. Maybe I missed something? --=20 With respect, Roman --Sig_/Mizx6BAu+d1pQjiIuH8GddO Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk2S7qgACgkQTLKSvz+PZwhXPwCeL7MhqAuHot7oEhg08887ujJY JmUAoJgFhKpclT9iWSgS06kYQN84xaOt =VJKp -----END PGP SIGNATURE----- --Sig_/Mizx6BAu+d1pQjiIuH8GddO--
