RNDX4000 - Disk scrubbing skipped due to degraded OS volume

[Chrish5]

Hi, Disk Scrubbing hasn't been happening since I replaced all disks, under 'Volumes' I get the following;

Configuration:   RAID Level X-RAID2, 4 disks   
Status:   Redundant   

RAID Disks:
 Ch 1 : Seagate ST2000VN000-1HJ164 [1863 GB]  461 GB allocated   
 Ch 2 : Seagate ST2000VN000-1HJ164 [1863 GB]  461 GB allocated   
 Ch 3 : Seagate ST2000VN000-1HJ164 [1863 GB]  461 GB allocated   
 Ch 4 : Seagate ST2000VN000-1HJ164 [1863 GB]  461 GB allocated   

(With green icons next to each drive).

In the log I get

"Disk scrubbing skipped due to degraded OS volume. [Volume C]"

So how can I fix the degraded volume?

RAIDiator v 4.2.28 (latest available as far as I'm aware)

You won't be able to fix that from the GUI. You can download the logs and check and the beginning of the mdstat.log file, it should show the status of the RAID arrays.

Thanks, I started looking through the logs on Friday but wasn't sure which one(s) I should be looking at.  Here's my mdstat log;
