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?

I am not aware of any software only solution to stripe the system disk on VMS.

Hmm. Maybe I'm misremembering then...

Maybe this?
init disk1: vol1
init disk2: vol2
mount/bind=vol disk1:,disk2: vol1 vol2
From then on add files to disk1: and both will fill up evenly

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$data
dismount disk1:
dismount disk2:
mount/for disk1
mount/for disk2:
mount/for tape1:
backup tape1:bound.sav/sav disk1:,disk2:/noinit
dismount tape1:
dismount disk1:
dismount disk2:
remounting restored bound data volume:
mount/system disk1: vol1
mount/system disk2: vol2
(mounting them one at a time allows for not having to modify your mount script)
(but you should do mount/system/bind=vol disk1:,disk2: vol1, vol2 user$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.

Just re-visiting.. No more hobbyist licenses? Is that from vmssoftware.com, no 'community' licenses?

I recall that the disks failed on the public access VMS systems that included Fafner

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
