This is the dmesg at boot time: ad0: 117246MB [238216/16/63] at ata0-master UDMA100 ad2: 117246MB [238216/16/63] at ata1-master UDMA100 GEOM_MIRROR: Device gm0 created (id=2190829866). GEOM_MIRROR: Device gm0: provider ad0 detected. GEOM_MIRROR: Device gm0: provider ad2 detected. GEOM_MIRROR: Device gm0: provider ad2 activated. GEOM_MIRROR: Device gm0: provider mirror/gm0 launched. GEOM_MIRROR: Device gm0: rebuilding provider ad0. GEOM_MIRROR: Device gm0: provider ad0 disconnected. The problem is that after reboot the gm0 mirror is DEGRADED. Why? After I "gmirror forget" it and then "gmirror insert" it back, it is COMPLETE again. I have tried to read all sectors of the drive but the drive seem not to be failing (smartctl also shows no indication of an error). This started to happen after a while; before (quite some time after gmirror was set up), everything worked perfectly. Any ideas? Thanks, Nejc
