Swap partitions must also be made on every drive. Points 1., 2. (and 4.) also could be solved by setting up a gmirror(8) raid1 array on the partitions in question. This works w/o the dump/restore/cron and the setup process is very simple. There is also a gstripe(8) and a gconcat(8) geom-class available in 5.3. - -- Christian Hiris <4711@chello.at> | OpenPGP KeyID 0x3BCA53BE OpenPGP-Key at hkp://wwwkeys.eu.pgp.net and http://pgp.mit.edu -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQFBoLSu09WjGjvKU74RAsVTAJ9fhTjB1ZM2xLL8qom7XjnwkSlTqwCfYFNs O3aVVBC5ksXfYc5aYrgrS8I= =xqaZ -----END PGP SIGNATURE-----
