I tried creating the mirror before the install. As the drives are now mirrored, the installer picked up on the face that there are two gm0 nodes - one on each hard drive. I installed onto ada0's gm0 node. After it reboots, the bootloader stops at the manual prompt. From what I can see that's not dissapeared up the screen, it tried and failed to mount from mirror/gm0s1a with error 19. I had to mount from ada0s1a in order for the boot to get further, but as it's been installed to boot from gm0s1x, it stops after it mounts /. After having checked my partition setup many times at this point, I know for a fact there's a rather large 500MB section free at the end of my hard drives with this partition set up. Is there any reason I can't just install as normal, do a 'gmirror label gm0 ada0', and then do a 'gmirror insert gm0 ada1', before changing my fstab to use mirror/gm0? I can't see why dumping and restoring is necessary, it's just manually doing what gmirror is there for in the first place. Correct me if I'm wrong :) On 9 October 2013 00:11, Warren Block <wblock@wonkity.com> wrote: > On Tue, 8 Oct 2013, Andy Zammy wrote: > > # gpart show ada0s1 >> gpart: No such geom: ada0s1 >> >> By the way, this is after a restart of the machine. >> >> There's nothing to back up, I'm installing a fresh os, so I just install >> on one drive, plug the other in, and start following the handbook >> instructions for this method.
