누군가 이 파티션 테이블을 이해하도록 도와줄 수 있나요?

누군가 이 파티션 테이블을 이해하도록 도와줄 수 있나요?

구형 HPC를 상속받았는데 더 많은 저장 공간이 필요합니다. 그러나 나는 여기서는 너무 깊이 빠져 있습니다. 첫째, 나는 먼저 내가 가지고 있는 것을 이해하려고 노력합니다. 그러나 나는 partedHere's parted와 비교하여 출력을 이해하지 못합니다 .df

답변1

기본 장치가 /dev/mapper매핑됩니다. 즉, 여러 파티션(물리적으로 분리된 하드 드라이브도 포함)이 하나 이상의 가상 파티션으로 결합됩니다.

내 생각에는 당신 이 와 를 어떻게, 어디에 sd[b-e,g-h]사용 하고 있는지 알아낼 수 있어야 한다고 생각합니다 . 아마도 더 좋을 것입니다.lsblkdmsetup deps -o /dev/mapper/<device-name>dmsetup ls --tree
