Zorluk: KolayStorage Drives and RAID Array Issues

A workstation configured with a two-disk software RAID 1 volume displays a notification indicating that the array status is degraded due to a disk failure on Drive 1. The workstation remains operational, but data fault tolerance is lost. Which of the following is the most appropriate action for a technician to take to restore full redundancy?

  1. Replace the failed drive with a new drive of equal or greater capacity and rebuild the volume.Cevap
  2. B
    Reformat all drives in the storage pool and recreate the RAID 1 array from a fresh initialization.
  3. C
    Convert the degraded array to a RAID 0 striping volume to bypass the missing disk error.
  4. D
    Run a full S.M.A.R.T. diagnostic check on the remaining healthy drive to bring the failed disk online.

Cevap

Replace the failed drive with a new drive of equal or greater capacity and rebuild the volume.
In a RAID 1 (mirroring) setup, a single drive failure degrades the array but keeps data accessible via the surviving disk. The standard recovery procedure is to hot-swap or replace the failed drive with a disk of equal or larger capacity and rebuild the mirror.

Adım Adım Çözüm

1
Identify the status of the RAID 1 array
The array is operating in a degraded state because one of the two mirrored disks has failed.
RAID 1 requires both disks operational for complete real-time redundancy.
2
Determine the necessary recovery step
Swap out the defective disk with a healthy drive that meets or exceeds the original drive's storage capacity.
Mirroring relies on having sufficient target block space to replicate data from the remaining functional drive.
3
Initiate the RAID rebuild process
Data from the surviving disk is copied to the new replacement drive, returning the array to optimal health.
Rebuilding restores data fault tolerance and redundancy.
