hmm. That is kind of a problem. I should have more than sufficient space now, but the allocation of
where it goes could overflow if the planning is blind to the storage allocations. Maybe that is
something to be developed?
As to where to report the storage use, the Amanda report doesn't have much space for another column.
However, the Dump Summary could be broken into separate Dump Summary tables for each storage. I can
obviously look at my configuration files to see where things go, but it would be reassuring to have
the Amanda report reflect that.
As for my current configuration, I created a pseudo tapetype that has a length equal to the sum of
what I expect to be able to write to one LTO6 plus one LTO7 tape. I put that as the global tapetype,
with runtapes=1. Each storage still references it's own tpchanger and tapetype.

It doesn't, it use the size and plan to dump less than that.

That's the problem, some DLEs will fail unless you have enough holdingdisk.
I never liked the idea that amanda delay some full dump because it do
not have enough tape space, It get worse at every days
The solution to never hit that problem is to always provide enough tape,
you could increase the runtapes of both storage.

Where would you like the information to be printed.
You can run 'amadmin CONF find', it should list the storage for each DLEs.
