Zorluk: OrtaStorage Drives and RAID Array Issues

An IT technician receives an automated notification from a server utilizing a two-disk hardware RAID 1 array. The alert reports that Disk 0 has reached a S.M.A.R.T. predictive failure threshold and the volume status is degraded, although the operating system is still online and functional. Which of the following is the best immediate action to restore full redundancy?

  1. Replace Disk 0 with an equivalent replacement drive and initiate an array rebuild.Cevap
  2. B
    Format the array volume and restore the data from the most recent system backup.
  3. C
    Convert the degraded RAID 1 volume into a RAID 0 array to bypass the failing drive.
  4. D
    Delete the array partition and perform a low-level disk initialization on Disk 0 to clear the S.M.A.R.T. status.

Cevap

Replace Disk 0 with an equivalent replacement drive and initiate an array rebuild.
Replacing the failing disk and allowing the controller to rebuild the mirror is the correct procedure for a degraded RAID 1 array. Because RAID 1 maintains an exact duplicate of the volume on the second drive, data remains fully accessible and redundancy can be restored by replacing only the compromised drive.

Adım Adım Çözüm

1
Identify drive status
Disk 0 is marked with a predictive S.M.A.R.T. failure while Disk 1 remains fully functional in a degraded RAID 1 state.
RAID 1 mirrors data across two drives, meaning Disk 1 contains a complete, functional copy of all data.
2
Determine corrective procedure
Hot-swap or replace Disk 0 with a drive of equal or greater capacity.
Replacing the failing hardware prevents total array failure before Disk 0 experiences complete physical failure.
3
Rebuild the mirrored array
The controller mirrors existing data from Disk 1 onto the new drive.
Rebuilding restores drive redundancy while keeping services online.
