No. On Solaris write cache is disabled by default AFAIK, because of UFS, so ZFS on Solaris doesn't turn on write cache when it is configured on a slice, because another slice may have UFS. On FreeBSD write cache is enabled by default, so ZFS bascially doesn't touch it. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
