Any insight would be > appreciated. gmirror shouldn't care what the underlying type is though using freebsd may confuse future tools that expect to find a bsdlabel on the partition. That being said, I'd be pretty surprised if mirroring your swap partition did anything other than causing pain and preventing coredumps. You can have quite a number of swap partitions so why not just add both and have twice as much (plus the chance to successfully produce a core dump if you need to debug something). -- Brooks --ikeVEW9yuYc//A+q Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iD8DBQFJZmBBXY6L6fI4GtQRAlDPAJ9VYrYj3HNq1pEqTAPKT4Dnm7AZWgCgsoOV f3mcWDMXITe9KwbColrIBrs= =Vxri -----END PGP SIGNATURE----- --ikeVEW9yuYc//A+q--
