Hi, I have been trying to setup a geom mirror on this machine but each time I reboot geom gives an error and only use one disk. Anybody know where I should look? I have two other machines that work properly. :-/ Anyway here are some more detail. I'm running the latest RELENG_5 with Pawel's with g_mirror.c v 1.34 and 1.35 from current applied. After syncing and rebooting I see these messages: ##################################################### ad0: 114473MB <ST3120022A/8.54> [232581/16/63] at ata0-master UDMA100 ad2: 114473MB <ST3120022A/8.54> [232581/16/63] at ata1-master UDMA100 GEOM_MIRROR: Device gm0 created (id=861616013).
