Package: mdadm Version: debian 13 trixie, debian 12 bookworm and probably earlier versions. Severity: important
When an array is created or modified, new disks are added. The add command takes a parameter, which must be a partition of an existing disk e.g. /dev/sda1 If the user only specifies a device e.g. /dev/sda, mdadm will claim the disk has been added and show all normal indications and messages for the device. For example it shows that the array is building and syncing with the progress updates. However, the array will not start at boot time and no error messages are given to indicate why the array failed to start.
