I tried to rewrite to use the system drive and a new one based on your patch and a material which I used for an in-house training: http://people.allbsd.org/~hrs/FreeBSD/geom-mirror.html http://people.allbsd.org/~hrs/FreeBSD/geom-chapter.20120604-1.diff I think the most difficult part of this procedure is copying the partition table, but is this version still difficult for the average user? I intentionally removed labeling and alignment handling because I feel they are rather complex when explaining how to convert a single-disk system to one with a mirrored disk containing the exactly same layout and data, though I fully agree that they are also useful and important. At least, labels of "alpha" and "beta" would be inefficient because "gmirror status" does not show the labels as the provider names, and gmirror member disks are recognized even if /dev/ada0 is moved to /dev/ada6, for example. -- Hiroki ----Security_Multipart(Mon_Jun__4_18_23_31_2012_181)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iEYEABECAAYFAk/MfpMACgkQTyzT2CeTzy1b4ACeLS4SVU0ZH641TWDUgeI+0+ik N2AAn0sWHd9Alcal5QvtgRlfn/eJL1D+ =8VMb -----END PGP SIGNATURE----- ----Security_Multipart(Mon_Jun__4_18_23_31_2012_181)----
