Hi Thomas, I'm just having a question, ext4 as a limit of 1EB total partition
size and 16TB for one file, are you really touching that limit ?
Perhaps it would be easier to split backups into limited size volume like 1TB
each ?
Or said differently, why did you choose the strategy you're using right now.
It is possible to have several devices in a directory storage resource.
so basically in director storage configuration you will end up with
Storage {
Name = ...
sdaddress = xxxx
Device = FileStorage
Device = FileStorage2
Media Type = File
}
Now I'm not 100% sure about the expected behavior you want.
(Fill up FS1 first, then fill FS2)
It will have more to do with volume in pool, and my personal choice is to stay
away of things that "magically" do something I can't describe and be 100%
reproducible, and able to explain to operator.
But that's only my way of life :-)
