Instead, use four separate swap partitions, one on each drive. As long as they all have the same priority, the kernel will share swap duties between them equally. There's no real benefit to using RAID for swap, unless you are limited on RAM and use swap a lot, when RAID0 may help. --=20 Neil Bothwick Excuse me for butting in, but I'm interrupt-driven. --Sig_7=NEPN5KeD43SUFnKeBOaxo Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFDoo26um4al0N1GQMRAs9AAJ9soaY8IxWELx9CK5RcUEfwUuqtTwCeIMnV X2Wyw3Cshq/xgxp34dHR8lY= =9m0v -----END PGP SIGNATURE----- --Sig_7=NEPN5KeD43SUFnKeBOaxo-- -- gentoo-user@gentoo.org mailing list
