"before I blow away data on da0a " I meant to say blow the data away on da1a, i.e. the / that is currently mounted, when it should be /dev/mirror/md0 according to fstab. My fstab only has refereence to / as /dev/mirror/md0 and nothing else. /dev/mirror/md0 / ufs rw 1 1 I obviously installed the system onto the second disk to start with, and issue boot dka1 to boot onto the second disk from SRM (not made anything permanent yet in SRM) Yet, even when i pass boot dka0 to SRM, dka0 in SRM = da0 in BSD, / still mounts off the second disk.. Something in the boot process is picking /dev/da1a up as root, right after GEOM_MIRROR starts... as per the last line but one in this boot output..... da1 at ahc0 bus 0 target 1 lun 0 da1: <IBM DDYS-T18350N S96H> Fixed Direct Access SCSI-3 device da1: 160.000MB/s transfers (80.000MHz, offset 63, 16bit), Tagged Queueing Enabled da1: 17501MB (35843670 512 byte sectors: 255H 63S/T 2231C) GEOM_MIRROR: Device md0 created (id=2875931076).
