State database replicas with no slices available

Question

Hi
I want to mirror a boot disk on Solaris 9 Sparc. All slices have file systems on them. Do I need to reformat the disk to make slices available or is there another way? I read some where about reclaiming space from swap but I'm not sure how this creates another slice unless they meant to take the space from swap and add it to a free slice if there wasn't enough space on the free slice.

Answer 1

Well, you can share a slice with a replica and a metadevice. But maintenance of that is really annoying.
If you must, you could do this:
#1 disable swap
#2 put a replica (or replicas) on the swap slice
#3 Create a metadevice on the same slice
#4 Create a mirror metadevice pointing at the one in #3 (if you want)
#5 Enable swap on the mirror metadevice.
You lose some flexibility with this arrangement, but it is functional.
It doesn't have to be swap, but that's the only slice that you can easily shrink/dice whatever on most machines.
