--3Gf/FFewwPeBMqCJ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello I have 4 IDE disks that I'm going to use for a small RAID. During my testing with the ata(4) software RAID I had created a RAID0 on two of the disks. I then deleted it and tried to create a new array (different interleave) but I had forgotten to unmounted the filesystem on the RAID I just deleted and I got a kernel panic - at least i think that was the sequence of events. The problem is that the RAID configuration was apparently left in a somewhat undefined state so now there is neither a configured RAID (no ar device) or any normal ad devices for the two disks. When I got the panic I was running a older 4.7-RC but I now run -CURRENT =66rom today on it (dual boot). I have the same problem with the "missing" disks under 4.7-RC and 4.8-RELEASE. I can still create a new RAID on the two remaining disk. Since updating the -CURRENT today I get a panic when creating the array (on ad8 and ad10) but after reboot the array is configured and works. I'm currently trying to create a proper crash dump for this but i'm rather sure this is unreleated to the "missing" disks.
