That is true, but using a single device for a dedicated ZIL is a huge no-no, considering it's an intent log, it's used to reconstruct the pool in case of a power failure for example, should such an event occur at the same time as a ZIL provider dies, you lose the entire pool because there is no way to recover it, so if ZIL gets put "elsewhere", that elsewhere really should be a mirror and sadly I don't see myself affording to use 2 SSDs for my setup :) - Sincerely, Dan Naumov _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
