While testing (simulating) replace and rebuild of failed drive there's no need to physically remove nor repartition disk. You'll place load on filesystem residing on R5 array, then simply force stop (stop -f) one subdisk. After a while running in degraded mode will simply start the subdisk again and reviving process starts. At the end you can be sure that newfs and restore of data is in order. Haven't had any other experience. Smells like FUD but isn't. -- Vallo Kallaste kalts@estpak.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
