The Handbook is your friend:

<snip>
In fact, unless your hardware requires you to run 5.x, I'd strongly
recommend that you stick with 4.8-RELEASE (or 4.9-RELEASE due out in
the next few weeks).

Thanks. I read that handbook chapter, together with <http://www.freebsd.org/doc/en_US.ISO8859-1/articles/vinum/index.html> and lots of other stuff, and I think my head is about to explode :)


Since this isn't really a production server I'm afraid I ignored your advice and went for 5.1. I partitioned the disks much as described in the 'Bootstrapping Vinum' article. I've just about got my head around how the setup described there works, but it seems there are better ways of doing things on 5.1. Trouble is, I can't work out what they are, or how to get from where I am to there.

It seems I need to create a vinum volume for my root filesystem. I can't (I think) just create a volume overlapping the existing root filesystem because it is at the beginning of the disk. Without allowing for Vinum's headers my MBR is likely to get trashed.

Compared to the example in the handbook life is slightly complicated by the fact that I have swap partitions second on both disks, so I'm guessing I need two vinum partitions per disk, one overlapping everything before the swap, and one overlapping everything after.

So, can I copy my root filesystem to somewhere else, create a vinum volume for root somewhere near the beginning of the disk but allowing for the requisite 265 blocks at the beginning and then copy the root filesystem back to this? I'm presuming some of this may need to be done from a fixit media.

Or should I just start again with a different arrangements of partitions? I've done nothing but install vanilla 5.1 so far, so this is not a major problem. Except that the machine boots fine off a CD, but then refuses to see the CD as installation media so I had to install over FTP - not the fastest way of doing things :(

Thanks for any help
