Veeam의 백업 저장소로 사용하는 RHEL이 포함된 가상 머신이 있습니다. 이제 백업을 위해 파티션을 확장해야 합니다.
- 원본 크기는 17TB입니다.
- VMware의 HDD를 19TB(VMware의 두 번째 HDD)로 확장하고 VM을 다시 시작했습니다.
- 재부팅 후
fdisk -l출력에 19TB 가상 디스크에 대한 일부 정보가 표시되지만 백업 경로는 여전히 17TB입니다./backup(/dev/mapper/vg02-backup)
출력은 fdisk -l다음과 같습니다.
[root@bckrepo01 ~]# fdisk -l

당신의 도움에 감사드립니다

유틸리티를 설치하고 growpart(패키지 이름은 cloud-utils-growpart일부 배포판에서 다를 수 있음) 다음을 실행합니다.
sudo growpart /dev/sdb 2 #yes, with the space
sudo pvresize /dev/sdb2
그러면 평소와 같이 LVM에서 새 용량을 사용할 수 있습니다. 백업 LV에 모두 추가하려면:
sudo lvextend -l +100%FREE -r /dev/mapper/vg02-backup
