Hi
I'm getting from time to time this message:
md127 is a RAID5
Is my RAID failing?

The mdadm says it's clean, I'm receiving daily email, all of them reporting that the RAID is Clean

This message is appearing more often than I realized.
Some times keeps popping for long periods of time, and nor always showing "md127: unknown partition table" -

Have you ever cloned a disk? I'm guessing that the uuid is the same on /sdc and /sdd .
I don't know if this will work! But I would back up my data, fail ONE drive from the array, erase all partitions from said drive, repartition, add the drive back and wait for the array to rebuild' then repeat on the other drive. -

I've never cloned the disks
I had 3 x 320Gb in RAID5 and decided to grow to 3 x 1Tb
The process was, fail one drive, remove it, replace it for the 1Tb drive, rebuild RAID. This was made for all 3 drives.
After this I grew the partitions to accommodate the free space.
I'll try to find something about the uuid's -

You can use something like parted (e.g GParted live CD) to create a new UUID for a disk and probably there is something you can do directly in ClearOS. You'd probably have to unmount the disk first (I can't imagine you would not).
[edit]
Check out uuidgen and this article, for example.

I'm getting hundreds of these too showing up in Reports - Log Viewer - Messages!
Is this a kernel bug? my uuid's are all unique. -
