lose the pool. So if you

Thanks... but doesn't your description imply that the sync writes
would always be written twice?
That is correct, regardless of whether you have slog or not. In the case of
For several times now I've seen statements on this list implying
that a dedicated ZIL/SLOG device catching sync writes for the log,
also allows for more streamlined writes to the pool during normal
healthy TXG syncs, than is the case with the default ZIL located
within the pool.
