Right; OTOH, there is usually no more than one or two partitions which are under write pressure, so *usually* you'll find rebuilding, say, /dev/mirror/var and /dev/mirror/db (at least most of our gmirror-setup servers show that) On the third hand, if you have enough memory, ZFS is both simplier and more lazy regarding repairs ;) -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: ma...@freebsd.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- ma...@rinet.ru *** ------------------------------------------------------------------------ _______________________________________________ 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"
