** Description changed: Binary package hint: mdadm "mdadm --incremental" will save state in a map file under /var/run/mdadm/map. But in initramfs and early boot this directory does not exist. The state is then saved in /var/run/mdadm.map.new (man page incorrectly - says /var/run/mdadm.map) and not picked up later on, and hotplug devices - showing up later can not be matched correctly. + says /var/run/mdadm.map) and carried into the main system later on. This + means hotplug devices showing up later can not be matched by + --incremental correctly. (with a strange device busy failure) - This can be fixed by creating /var/run/mdadm in the initramfs *before* - the udevd is started in init-premount/udev (either during creation of - the initramfs image, or dynamicly (boot time consuming) in mdadm's - initramfs-tools init-top/mdadm script). + This can be fixed by: - The initramfs' /var/run has to be copied to the real /var/run as part of - the boot process so /var/run/mdadm/map carries on the valid - --incremental state. + * creating /var/run/mdadm in the initramfs *before* the udevd is started + in init-premount/udev (either during creation of the initramfs image, or + dynamicly (boot time consuming) in mdadm's initramfs-tools init- + top/mdadm script). + + * copying initramfs' /var/run the real /var/run as part of the boot + process so /var/run/mdadm/map carries on the valid --incremental state.
