Hello Everyone,
I was trying to set up a new gmirror with components ad4 and ad6 in a
machine which already has one, but the new gmirror doesn't finish syncing:
Jan 4 20:21:27 <0.2> isolde kernel: GEOM_MIRROR: Device mirror/gm1 launched (1/1).
Jan 4 21:22:32 <0.2> isolde kernel: GEOM_MIRROR: Device gm1: rebuilding provider ad6.
Jan 4 23:43:50 <0.2> isolde kernel: GEOM_MIRROR: Request failed (error=5). ad4[READ(offset=657053450240, length=131072)]
Jan 4 23:43:50 <0.2> isolde kernel: GEOM_MIRROR: Synchronization request failed (error=5). mirror/gm1[READ(offset=657053450240, length=131072)]
I then ran smartctl short and long tests on both ad4 and ad6:
# smartctl -l error /dev/ad4

No errors logged... but then:

So, my questions are:
- Do I have a bad hard drive (apparently, I do...)
- Why are there "No Errors Logged" by smartctl?
