No deduplication.

However, I have the trouble of a file class pool, collocated by filespace, 
showing full and not allowing backups even though the pool shows 75% full, just 
used itx maxscratch allocation.
This causes an inordinate amount of human interfvention to keep afew volumes 
below maxscratch.

I believe a fileclass storagepool is better suited for this kind of
"permanent" storage on disk.
A diskpool should be used for things such as disk between the backup client
and tape for temporary random I/O storage that can handle an unlimited
amount of sessions.
A fileclass storagepool is better suited for long term storage.
I create a diskpool for VE metadata when using dedup on the filepool and
use fileclass storagepools for permanent storage on disk with or without
deduplication.

Are you planning on using deduplication on disk?
