If you want Dedup to perform well, you *absolutely* must have a L2ARC
device which can hold the *entire* Dedup Table. Remember, the size of
the DDT is not dependent on the size of your data pool, but in the
number of zfs slabs which are contained in that pool (slab = record,

Hi Edward,
Do you have a source for the 8KiB block size data? whilst we can't avoid

I got about 222 zfs file systems, wanted to upgrade from version 3 to version 4.
How long does this operation take?
I just ran zfs upgrade -a, and it is taking a while.
