I build a VM Centos 6.3 system with 6 extra 1GB disks for testing. I found several issues in the standard installed 3.2.3 version of mdadm relating to ddf, but installed the 3.2.5 version in order to work with recent code. However, while version 3.2.3 is able to create a ddf container with raidsets in it, I found a problem with the 3.2.5 version. After initially creating the container: mdadm -C /dev/md127 -e ddf -l container /dev/sd[b-g] which worked, I created a raid (1 or 5 it doesn't matter in this case) in it: mdadm -C /dev/md0 -l raid5 -n 3 /dev/md127 However, it stays on resync=PENDING and readonly, and doesn't get build. So I tried to set it to readwrite: mdadm --readwrite /dev/md0 Unfortunately, it stays on readonly and doesn't get build. As said before, this did work in 3.2.3. Are you already on this problem? Kind regards, Albert P.S. My idea was, because the ddf code is not that much used, to create a test/validate script for ddf.
