datatomb2# uname -a
FreeBSD datatomb2.pluspunkthosting.de 8.2-STABLE FreeBSD 8.2-STABLE #0: Wed Dec 14 12:44:07 CET 2011     root at datatomb2.pluspunkthosting.de:/usr/obj/usr/src/sys/GENERIC  amd64

Yank disk:
ada1:GEOM_MIRROR: Device swap: provider ada1p2 disconnected.
(ahcich1:0:0:0): lost device
(ada1:ahcich1:0:0:0): removing device entry

Put it back in:
ada1 at ahcich1 bus 0 scbus2 target 0 lun 0
ada1: <ST31000340NS SN05> ATA-8 SATA 2.x device
ada1: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes)
ada1: Command Queueing enabled
ada1: 953869MB (1953525168 512 byte sectors: 16H 63S/T 16383C)

And I get ZFS v28, too :-))

Thanks and kind regards,
