The main problem here (currently) is the bootblocks and /etc/fstab. We had some work on geom_mirror recently which I have not yet had time to look at. If that is done right, it should be possible to set it up like you say. In order to "fool" the bootblocks, geom_mirror would have to be able to use a meta-data sector at the end of the partition rather than at the beginning. With that in place it should "just work", since the device in /etc/fstab would then be the geom_mirror device and GEOM should be able to offer that for root mounting. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk_at_FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.Received on Fri Nov 14 2003 - 14:32:12 UTC
