Comparing a fresh install with a alternate-desktop installed as single0drive, upgraded to raid, then 6.10-7.04:
#1. Both systems suffer from bug Bug #108971. Message "mdadm : No devices listed in conf file were found" on boot-up right after "Loading, please wait..." This is fixed by adding "/sbin/udevsettle" to the end of /usr/share/initramfs-tools/scripts/init-premount/udev, then issue command "update-initramfs -u -k `uname -r`" and reboot #2. This starts raid before raid is supposed to be started, and the upgraded system therefore gives an error message: Begin: Assembling MD array /dev/md1 ... mdadm: device /dev/md1 already active - cannot assemble it Failure: failed to start /dev/md1 It is unclear if this has any functional impact. The root cause is that the /conf/md.conf file in the RAM file system image initrd.img-... contains MD_DEVS='/dev/md1' instead of MD_DEVS='all' which is the case for fresh install (The image can be examined by "cpio -i </boot/initrd.img..." that unpacks it to the current directory) This can be fixed by inserting MD_DEVS=all on line 94 (the line after ..MD_DEGRADED..)in /usr/share/initramfs-tools/scripts/local-top/mdadm and issuing "update-initramfs -u -k `uname -r`" and reboot #3. Then I had a message " * Mount point '/var/run' does not exist. Skipping mount." just prior to " * Reading files needed to boot..." This originated from /etc/rcS.d/S01mountkernfs.sh and was caused by the /var/run folder missing on the root raid partition. This may be my mistake since an installed system was converted to raid. #4. There is, when everything works, a message " * Stopping MD array md2... [fail]" just before " * Will now restart" message on shutdown. This appears to have no impact. Also Red Hat has similar issues.
