권한 거부됨: /dev/sda4에서 mongodb를 시작할 수 없는 이유는 무엇입니까?

내 SDA에서 장치 속성 정보를 차단합니다.

sudo blkid

uuid를 사용하여 /mongodb를 /dev/sda4에 마운트하고 싶습니다 0cba040e-d9da-4285-b70e-b2a9b5290a1c.
내 /etc/fstab에 다음 줄을 추가했습니다.

UUID=0cba040e-d9da-4285-b70e-b2a9b5290a1c  /mongodb        ext4    rw,auto     0 1

다시 시작한 후 ls /mongodb로 이동합니다.

왜 mongodb를 시작할 수 없나요?

답변1

이미 말을 타고 있는 것 같습니다. loss+found는 FS 문제로 fsck를 시작할 때 검색된 파일이 발견된 EXT4 디렉토리입니다.

간단히 말해서 FS를 설치했습니다. 게시해 보세요:

df -h /mongodb
