I'm trying to add a second software RAID device to a system. I've created an image based on Mandrake 10 on a 20 GB hard disc that has the entire drive as a single RAID device (md0) that in turn contains an LVM2 physical volume.
This image boots without problems and works. The problem comes up when cloning the image to another disc. Upon imaging to the disc, things work fine until I attempt to assign the extra space to a second MD device. I can do it but getting the thing to start from the initial ramdisk results in:
md: could not lock hda
md: md_import_device returned -16
md: bug in file drivers/md/md.c line 1502
mkraid runs without a problem and raidstart --all does correctly start the array after boot.
Does anyone have any ideas? I'm running the "vanilla" mandrake kernel, 2.6.3-15mdk.
