Zorluk: OrtaStorage Drives and RAID Array Issues

A network technician receives an automated server alert indicating that a file server's storage volume is operating in a degraded state. Upon inspecting the system, the technician notes that the volume is hosted on a RAID 5 array consisting of four 2 TB SATA hard drives. RAID management software confirms that Drive 2 has suffered a hardware failure, while the remaining three drives continue to function correctly and data remains accessible. Which of the following actions should the technician take first to restore full fault tolerance to the array?

  1. Replace the failed drive with a new drive of equal or greater capacity and initiate an array rebuild.Cevap
  2. B
    Format all active drives in the array and restore the entire volume from the latest offline backup.
  3. C
    Break the RAID 5 configuration and reconfigure the remaining three drives into a RAID 0 array.
  4. D
    Execute a disk defragmentation and file system repair utility on the degraded volume before taking the drive offline.

Cevap

Replace the failed disk with a new, compatible disk of equal or greater capacity and rebuild the array.
Replacing the damaged drive with a functional drive of identical or larger capacity allows the RAID controller to use existing parity blocks across the functional member drives to rebuild missing data, restoring full fault tolerance.

Adım Adım Çözüm

1
Identify the status of the RAID 5 array and confirm single-drive failure failure limits.
RAID 5 can tolerate one drive failure using distributed parity across the remaining active drives.
Data remains readable from the active members of the array.
2
Remove the failed hard drive and insert a replacement drive of equal or greater capacity.
The physical hardware issue is addressed with a functional disk.
The controller requires a healthy target disk to recalculate and write missing parity and block data.
3
Initiate the RAID rebuild process via the storage management console.
Array redundancy is fully restored once parity reconstruction completes.
This action restores fault tolerance without unnecessary downtime or data destruction.
