How to recover RAID5 array when a hard drive fails

Operating System ZimaOS
1

I have two RAID arrays:

  1. a RAID5 array of four 12 TB disks
    and
  2. a RAID0 array of two 4 TB disks

Disk 2 of the RAID5 array has been marked as “Damaged”.

All other disks are marked as “Protecting”. Both arrays have been placed in read only mode by ZimaOS even though only the RAID5 array has the damaged disk.

I have a replacement drive ordered and it will be here tomorrow.

What is the protocol for replacing the drive marked as damaged and recovering the RAID5 array as well as restoring read/write access to both arrays without data loss?

Thanks for any help.

Well, that was much easier than expected. Powered down the cube, replaced the drive, powered up, followed the prompts, and the array is being recovered! ~13.5 hrs until completed. Hopefully one of the other drives don’t fail in the interim.
