When I try to use more than a certain amount (16TB?) of cache, and the "cache
disabled" message doesn't seem good.
I have a system with 24 600GB drives that works well, but a system with 24
900GB drives will have the above error, unless I disable at least 5 drives in
storage.config.
I tried splitting the cache up in to 2 volumes, each 50% in volume.config, but
I still get the same error.
