With gmirror.patch I don't see the geom_mirror error messages, but then it doesn't finish booting: ####################################################### GEOM_MIRROR: Device gm0 created (id=861616013) GEOM_MIRROR: Device gm0: provider ad0 detected GEOM_MIRROR: Device gm0: provider ad2 detected Mounting root from ufs:/dev/mirror/gm0s1a setrootbyname failed Root mount failed: 6 Manual root filesystem specification ... mountroot> ####################################################### So how do I go from here? Is there something else I can try? John -- John Hay -- John.Hay@icomtek.csir.co.za / jhay@FreeBSD.org
