Public bug reported: Binary package hint: mdadm
After rebooting my server, spares are not automatically re-inserted into my RAID5 and RAID1 arrays. I was able to get the above to work correctly by explicitly telling mdadm which partitions to scan: # extract from /etc/mdadm/mdadm.conf #DEVICE partitions DEVICE /dev/sd[abcdef][12] I think that this should work properly also in the case of "DEVICE partitions". Some information about my system below, followed by detailed disk and md configs.

This package automatically configures mdadm to assemble arrays during the system startup process. If not needed, this functionally can be disabled.
