First of all, you have a machine that is running a very old version of
OpenBSD. You have a lot of upgrades to do, and since you have other
issues (partitioning), you probably just want to reinstall and start
over using your current knowledge of your disk layout needs.
Well that's kind of the thing.
The machine is mainly used for messing around and testing stuff, so it
has a bunch of random things installed that will be a pain to move over.
Additionally, we occasionally use it to verify things against older
OpenBSD specifically (like, 4.9 was still using Apache for example).
Upgrading is certainly possible, it's just a question of which will
cause more pain in the end- that or repartitioning.
Since you are working on a 10G hard disk, you might want to consider
replacing that just because of its age (I say, as glance over at my
crate of 20G and smaller HDs), and 10G disks are just plain slow
compared to modern disks.
That will be a problem eventually yes. This machine doesn't have a lot
of disk activity though so so far the drive's been holding up. Speed
isn't that big of a deal.
The general answer to your question, however, is the "growfs" command.
growfs will let you expand an off-line file system with additional space
immediately adjoining the end of the partition.
OK.... that's the general answer providing we replace the disk with a
bigger one though, right? Is there a good way to use the same disk?
Again, the issue is not that the disk is full, but that's it half empty
and split up in a way that we can't really use the space.
