Question
One leg of an LVM-mirrored volume failed due to the underlying physical volume, and a systems administrator is troubleshooting the issue. The following output has been provided: Given this scenario, which of the following should the administrator do to recover this volume?
Options
- AReboot the server. The volume will automatically go back to linear mode.
- BReplace the failed drive and reconfigure the mirror.
- CReboot the server. The volume will revert to stripe mode.
- DRecreate the logical volume.
Explanation
{"question_number": 9, "explanation": "When a physical volume (PV) underlying one leg of an LVM mirror fails, the correct recovery procedure is to replace the failed physical drive and then reconfigure the mirror by adding the new PV back to the volume group and resyncing the mirror. LVM does not automatically convert a degraded mirror to linear or stripe mode on reboot - those are different logical volume types requiring manual reconfiguration. Recreating the logical volume would destroy all data. The mirror must be explicitly repaired using LVM tools like lvconvert after the hardware is replaced.", "generated_by": "claude-sonnet", "llm_judge_score": 5}
