Raid 5 active, clean, active, clean...

    • Raid 5 active, clean, active, clean...

      Hi!

      I just finished an upgrade of my raid 5. I had 4x3TB and now I have 4x8TB. I swapped disc by disc and everything went perfect. The raid is now working as intented.

      However, something weird is happening. The status shows the raid as active, and after that, clean. And after that, active. It looks like it is writing without stop, even when I am not using it.
