The mirror contains a full slice with all partitions. On load of geom_mirror, there are errors: acd0: FAILURE - READ_BIG ILLEGAL REQUEST asc=0x64 ascq=0x00 error=4<ABORTED> This _only_ happens, if I have a medium in the cdrom drive. On boot, the activation of ad0 hangs, because of the error on acd0. What seems to happen is, that the default mirror.timout=4 forces the mirror to start without ad0. The mirror comes up not only in degraded state, but ad0 is missing at all. I'm able to reattach the ad0 provider, but this causes a full resync of the mirror.

I'm not shure about this one.) or Do not have a medium in your CDROM or Do not have a CDROM Drive together with a geom providing harddrive on the same Channel at all.
