I think you want glabel label swap /dev/ad0s1b 'create' is the manual method which won't store any metadata - 'label' stores it in the last sector of the provider. > And the system wants me to enter the root FS name manually because > ad0 is locked by GEOM and ad0s1a can't be mounted therefore. > GEOM_LABEL finds the label before GEOM_MIRROR is started properly. > > I've experienced this behaviour on both 7.2 and, I think, 8.0 too > (May snapshot). > I know we don't really need labels on a gmirror because a gmirror is > a 'label' in itself and will always appear as /dev/mirror/device-name > no matter how we swap HDDs and no matter in which order they are > probed, however this is still a bit strange. I think if you use label you'd be OK (but you'd need to newfs because the created provider is 1 sector smaller). The other alternative is to use /dev/ufsid/xxx which won't require a newfs as your existing FS's have an ID already (presuming you are using GENERIC). -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
