The more slog devices, the better. :) If the host using the slogs could trigger the shutdown, that would be even better I think. Once we know the zpool is exported, the slogs have just entered a nicely consistent state at which point the copies could be made. Also, it would also be nice if the host using these slogs would be able to wait until enough of them are online to attempt to mount its pool. That shouldn't be too hard, nothing more than some startup script modifications. -brian -- "Coding in C is like sending a 3 year old to do groceries.
