I installed on a Mink 16 a RAID 5 for backup purpose on my portable PC: it worked BUT gnome-disks reported the Raid to be "degraded" and to fix it it would took something like 20 hours.
I did the same on a different portable PC with Mint 14 and haven't got the problem.
Now switching the Raid from a PC to another everything works, but the one with Mint 16 continue to claim that the Raid is degraded, while on the Mint 14 it is reported as OK.
As it is a backub system I would like to be sure that everything is OK.
Below all the tech details, and the only visible (to me) difference is the version of gnome-disk-utility.
Thanks, evelino
