When you are creating the composite gmirror device you are effectively labeling it anyway i.e. gmirror label gm0... Now if you follow the usual tutorials found in the web you would be using gm0 / gm1 but you actually name it any way you wish. If you really need to label the separate gmirrored partitions, do it after setting up the mirror.
Concerning the order of journals and mirroring, I create the journals first, then mirror the result. This has always worked fine for me. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
