Zorluk: ZorStorage Drives and RAID Array Issues

A system administrator is replacing a failed M.2 NVMe SSD in a degraded RAID 5 volume on a server motherboard whose M.2 PCIe slots do not support hot-swapping. Place the troubleshooting and drive replacement steps in the correct sequential order from first to last to safely restore volume redundancy.

  1. 1Perform a full data backup of the degraded RAID volume to an external storage target.
  2. 2Gracefully shut down the operating system and disconnect all main power sources.
  3. 3Physically replace the defective M.2 NVMe SSD with a new drive of equal or greater storage capacity.
  4. 4Power on the host system, access the RAID management interface, and initiate the array rebuild onto the replacement SSD.
  5. 5Execute a RAID volume consistency check to confirm parity integrity across all member disks.

Cevap

The correct sequence of actions is: 1) Perform a full data backup of the degraded RAID volume, 2) Gracefully shut down the operating system and disconnect main power, 3) Physically replace the defective M.2 NVMe SSD with a drive of equal or greater capacity, 4) Power on the system, access RAID management, and initiate the rebuild, 5) Execute a RAID volume consistency check.
The correct procedural order ensures data safety first by taking a backup of the degraded array, respects hardware limitations by powering off before handling non-hot-swappable M.2 slots, re-establishes logical redundancy via the RAID manager, and validates array health with a final parity consistency scan.

Adım Adım Çözüm

1
Back up all critical files from the degraded array immediately.
Protects existing data against array destruction if an unrecoverable read error or secondary disk failure occurs during maintenance.
RAID 5 offers single-drive fault tolerance; operating in a degraded state leaves zero room for additional drive errors.
2
Shut down the server cleanly and unplug the electrical connection.
Safely removes voltage from non-hot-swappable M.2 PCIe slots on the system board.
Standard desktop and server motherboard M.2 slots require cold-swapping.
3
Remove the failed M.2 drive and install a functioning replacement drive.
Provides the physical disk capacity required to re-establish the RAID array parity structure.
The replacement disk must meet or exceed the capacity of the original member disk to be accepted into the array.
4
Boot into the system RAID configuration software and assign the new drive to begin array rebuilding.
Triggers the RAID controller to compute missing parity data and populate the replacement drive.
Hardware array controllers require manual assignment or initialization when non-hot-swapped drives are added.
5
Run a full parity consistency check across the newly rebuilt array.
Validates overall volume health and confirms no underlying disk read errors remain.
Verifies array integrity before returning the server volume to active production workloads.
