So I'm getting back into dabbling with VMS, what with all the talk surrounding the end of the hobbyist program. Got my final PAK, got 8.4 set up on an Alpha workstation I got as a rescue, got the basics configured...but now I'm wracking my brain trying to remember how to set up a spanned filesystem, which I swear I had going on my VAXStation last time I was puttering around with this.
Basically, I really would like to have the system treating the two hard disks as one uniform storage space and spanning files across them transparently, since the only compatible disks I have on hand are in the 1-2 GB range and I'd like to get some more software installed...only problem is, when I went to look at the documentation for volume sets, one of the first things it says is *not* to include the system disk in a volume set. I swear I had this set up on my VAXStation, but it's been some years since I was last digging into this, and I never was super familiar with it...*is* there a way to do this?
Image backup of bound volume:
backup/image disk1: tape1:bound.bck/sav/label=bound/rewind
Image restore of bound volume:
init disk1: vol1
init disk2: vol2
mount/bind=vol disk1:,disk2: vol1,vol2 user$data
backup tape1:bound.sav/sav disk1:,disk2:/noinit
remounting restored bound data volume:
mount/system disk1: vol1
mount/system disk2: vol2
(mounting them one at a time allows for not having to modify your mount script)
(but you should do mount/system/bind=vol disk1:,disk2: vol1, vol2 user$data)
One benefit is that smaller disks bound together use the same cluster size for each of the disks so you don't loose space if it was one large disk. On the down side, if these disks are served out by an HSx raid controller, all you can do is add a mirror for each individual disk where it would have been better to raid them all for one large volume and live with the larger cluster size that is unless you were running 7.x, then you could specify a smaller cluster size.
