It can occur that the raid refuses to resync completely when a new disk has been added to the SME and that this disk is "a little bit" smaller than the disk what is already running.
The raid sync (e.g. started from the console) works of "/", for "/boot" but not for the swap because os missing some space on the added disk.

=== The RAID array: ===
* stop the swap:
* stop the swap:
# swapoff -a
# swapoff -a
* Check that the UUID and the name are correct and wait the end of the sync.

Open /etc/fstab and remember the UUID set for the swap file system

{{Tip box|Reusing the "old" UUIDs makes the thing simple because there is no need to change any parameter in the configuration of the SME.}}
