You could use gconcat, but you'd have to partition, label and newfs this new combined device which would render your current data unreadable. And on a concatenated disk the risk of failure is increased. If one of the two drives dies, you'll lose all data. If you want to combine disks, use some form of RAID to protect yourself from a dying disk. :-) Roland --=20 R.F.Smith http://www.xs4all.nl/~rsmith/ [plain text _non-HTML_ PGP/GnuPG encrypted/signed email much appreciated] pgp: 1A2B 477F 9970 BA3C 2914 B7CE 1277 EFB0 C321 A725 (KeyID: C321A725) --A6N2fC+uXW/VQSAv Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iEYEARECAAYFAkqVfXUACgkQEnfvsMMhpyUfFgCdG4FYGOCSzEtadfuNJup1bWpt DMQAnjTzqIYtNLjaK6pbCoiCLH0x+75I =DEs6 -----END PGP SIGNATURE----- --A6N2fC+uXW/VQSAv--
