I've just gotten NetBSD 6.1.5 set up on a MicroVAX 3100/90 I recently acquired. It came with four 406MB SCSI hard drives, and since I'm on a tight budget, it's going to be keeping those four 406MB drives for the foreseeable future. Currently it's just got / mapped to a full-drive partition on sd0/dka0 (on account of the installer not being able to set up partitions on multiple disks.) What I'd like to do with it is get it set up so that it makes good use of the available disk space.

Mostly that's just a matter of copying out different parts of the filesystem to new partitions on the other disks and then changing fstab, but one thing I'd specifically like to do is have a /usr partition larger than 406MB, since it seems like the majority of pretty much any non-core stuff gets installed in /usr. I'm curious - I know there's relatively simple ways to mirror a partition across multiple disks, but is there an easy way to actually spread a larger virtual partition across a couple different physical partitions?

I suppose if nothing else I could map some of the /usr subdirectories to different partitions, but a true virtual partition seems like it would be a more flexible, simpler solution.

(And as an aside, is there any viable way to get a working compiler toolchain running natively on NetBSD/vax?)
