Re: Geom RAID root report.
The easiest way is to chroot into the fixit CD's filesystem and then gmirror load. That way the hardcoded path is correct and it works.

Geom RAID root report.
Before making this machine, I did a search on the lists to see if anyone else had questions or was willing to report on using a GEOM RAID root device. Nobody had. So... here's the basic recipe. First I did a minimal install to one of the two disks in a 512M root. I think 256M would be enough for that, but the disks are just so bloody huge. Anyways... then I booted from the fix-it CD to try to mirror up the 'a' partition. Gmirror on the fix-it CD appears to be impotent. It appears to have only 'help', 'list', 'load' and 'unload' as commands. Not useful. Since I had a few spare disks around, I loaded a default load onto one and tried again. The disklabel created by sysinstall had the 'a' pertition starting at 0. Creating a gmirror starting at the beginning of a disk or ending at the end seems to break things, and it did here. Gmirror (the kernel module) seems to find the provider as the parent (say ad4s1) instead of the child (ad4s1a). So I used 'dump' to image 'a' and then I relabeled and repartioned the disk to start 'a' at block 64. gmirror on this worked and formatting it and restoring to it are fine. Now... you do need to mount this filesystem and edit a few things. geom_mirror_load=YES needs to be in /boot/loader.conf Your fstab will likely need to look like: # DeviceMountpoint FStype Options DumpPass# /dev/mirror/cs-swap noneswapsw 0 0 /dev/mirror/cs-root / ufs rw 1 1 /dev/mirror/cs-var /varufs rw 2 2 /dev/mirror/cs-usr /usrufs rw 2 2 ... obviously substituting your own geom mirror names. Note that using a geom swap requires swapoff=YES in /etc/rc.conf But otherwise, this all seems to work ... even without the nasty recalculation of the fake 'a' partition required by vinum.
