[Fortinet] FortiAnalyer DISK - Spare 상태 분석

1. FortiAnalyer DISK RAID 상태 분석

 

Fortinet 관련 장비 로그를 수집하는 포티 아날라이저 제품에서

System Settings - RAID Management 탭에 들어가면,

 

RIAD Level, Status, Disk Space Usage 등의 정보와 Disk management를 확인할 수 있다.

이 중 Disk Managment에서, Disk Number 별 Disk Status / Size(GB) / DiskModel를 한눈에 볼 수 있다.

 

Disk Status 표현 값은 Unused (사용 안 함) / Spare / Ready (정상)가 있다.

여기서 Spare 상태가 되는 경우를 알아보자.

Disk indicate as Spare in RAID status

 

 

2. Technical Tip: Disk indicate as Spare in RAID status

Description

 

This article describes why RAID information shows the disk as 'Spare' and how to fix the issue. This happens sometimes when new RMA replacement disks are replaced.

 

Scope

 

FortiAnalyzer

 

FAZ # diagnose system raid status

Mega RAID:
RAID Level: Raid-50s
RAID Status: Degraded
RAID Size: 201170GB
File System: ext4 200144GB
Groups: 6

Disk 0: OK 3726GB Group-1
Disk 1: OK 3726GB Group-1
Disk 2: OK 3726GB Group-1
Disk 3: OK 3726GB Group-1
Disk 4: OK 3726GB Group-1
Disk 5: Spare 29802GB
Disk 6: OK 3726GB Group-1
Disk 7: OK 3726GB Group-1

 

RAID status will show as Degraded, which means one of the disks has failed and is no longer being used by the controller.

Somehow the RAID level will show as 50s.

 

 

 

Solution

 

Confirmed CLI information on the below command:

 

FAZ # diagnose system disk info

 

Disk 4:
Vendor: SEAGATE
Product: ST4000NM0095

Disk 5:
Vendor: SEAGATE

Notice :

Disk 5 has a different Logical block size from the existing disk, which is why the RAID is not able to read properly.

Proceed to get the same disk model as the existing one for the replacement from the RMA team.

 

위의 예시를 보면 Disk 교체 후, Ready(정상)이 아닌 Spare Status 표기가 되는 이유는 다른 Disk와 Block Size가 같지 않아서 된다고 확인되며, 같은 디스크 모델로 진행하거나 RMA 팀에 문의하면 해결할 수 있습니다.
