Hello all.
I try to grow my RAID 6 array.
I went through the gui, erased my disk quickly, then increased my RAID array with the disk (sdo).
The disk is added but is not active, it is displayed in spare mode (hot-spare if I understood correctly).
Code

So, I try to grow the array with command line, but superblock error on sdo:
Code
root@bignas:~# mdadm --grow /dev/md127 --raid-devices=13
mdadm: /dev/md127: cannot get superblock from /dev/sdo
I tried to delete sdo again using the gui but not possible: device busy.
Can anyone give me some help so I can successfully increase the size of my file system?
Thanks à lot.
