새 디스크를 추가하려면 이 가이드를 따르세요.

그것은되었다 /dev/sdb.

실행 후 fdisk /dev/sdb파티션을 나눈다 . 다시 확인하세요:

예 Device boot./dev/sdb1

mkfs.ext4 /dev/sdb1하지만 형식을 실행하면 다음 오류가 발생합니다.

mke2fs 1.42.9 (28-Dec-2013)
/dev/sdb1 is apparently in use by the system; will not make a filesystem here!

왜? 포맷할 수 없나요? 사용하고 싶지만 /dev/sdb먼저 포맷해야 할 것 같습니다 /dev/sdb1. 더 이상은 아닙니다.

현재 drbd 테스트를 하고 있습니다. 이제 새 하드 드라이브와 파티션/포맷을 추가해야 합니다.

그럼 당신은 틀렸어요!

sdb생성 후에는 기본 장치( )에 쓰지 마십시오 drbd0. 대신 에 글을 쓰세요 drbd0. 이것은 또한 질문의 문제를 해결합니다.

이 시점에서 나는 그것을 파괴 drbd0하고 다시 만들 것입니다.
