Summary0000882: RAID: reinstallation causes raid to block installation until sync is finished
Descriptionwhen a system will be reinstalled which has disks which have been within a raid before, the installer will block during installation and wait until the raid have been completely rebuild. (may take about 70 hours, with 160G disks)

When this happens, the kernel gives this error:
md: created mdX
md: bind <hdaX>
md: bind <hdcX>
md: running: <hdcX><hdaX>
md: mdX: raid array is not clean -- starting background reconstruction
md: personality for level 1 is not loaded!
md: do_md_run() returned -22
md: mdX: stopped.
md: unbind<mdX>

i think this is the following bug: [^] .. page includes kernel-patch which seems to fix the problem.

Probably it is also sufficient to do the following within installer before creation of the new md devices:

mdadm --zero-superblock /dev/hda1
mdadm --zero-superblock /dev/hda3
mdadm --zero-superblock /dev/hda4
mdadm --zero-superblock /dev/hdc1
mdadm --zero-superblock /dev/hdc3
mdadm --zero-superblock /dev/hdc4

After this the disks should be non-raid disks and no kernel should start reconstruction of the raid .. (?)
