Do not use the admin account to add an SSD disk to a RAID1 set that is custum partitioned to use less than 100% of the disk space from the menu (Option 5. Manage disk redundancy) because the script behind this option will not check how the disk that needs to be cloned is partitioned.

The script will add the disk but will partition it using 100% of the disk space even when the first SSD disk in the RAID1 set is partitioned using less than 100% of the disk space.
