Case Study: RAID and Recovery

RAID disk failed and there is no compatible replacement

The server continued to operate in a degraded mode, but another failure could halt the company. It was necessary to protect data and restore reliability without risky actions.

Why couldn't we just wait for the disk?

The storage model has been discontinued, the array has already lost redundancy, and it's impossible to stop working services indefinitely.

Risk of repeated failure

If another disk fails, the array and working data could become inaccessible.

Data verification

Checked RAID status, error log, backup validity and recovery capability.

Temporary schema

We have prepared secure temporary storage and a migration plan until the installation of a compatible drive.

Description is anonymized: technical details and customer data are not disclosed.

Result

  • Critical data is protected until work with the array begins.
  • Storage status was monitored during migration.
  • A compatible disk was installed according to the prepared plan.
  • After rebuild, the array, backup, and test recovery were checked.

Is RAID operating in a degraded mode?

Don't wait for a second failure. We will check the array, backup and propose a safe course of action.
