What you want to hear? I'll advise you to not put critical data on the Vinum R5 volume. You did test this configuration thoroughly before putting online, did you? All this failing/replacing/rebuilding stuff? Better quiesce the volume (umount it) before rebuilding, doing otherwise causes data loss in my experience. You should use camcontrol when doing hot-swapping of drives. For the end, collect the debug information Greg Lehey (Vinum author) needs and submit it directly to him. -- Vallo Kallaste To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
