나는 ext4 파일 시스템을 갖춘 Toshiba 하드 드라이브를 가지고 있으며 어제까지 그것을 광범위하게 사용하고 있었습니다. 갑자기 읽기 전용 파일 시스템이 되어 실행했더니 fdisk -l유형이 HPFS/NTFS/exFAT.
읽다파일 시스템이 갑자기 읽기 전용이 됩니다. 이를 디버깅하는 방법은 무엇입니까?, 나는 시도했고 dmesg추가로 보여주었습니다 (거기 답변에서 제안한대로)
367.274847] EXT4-fs error (device sdb1): ext4_validate_block_bitmap:390: comm nextcloud: bg 7398: bad block bitmap checksum

물론, 마지막으로 작업했을 때 완전히 제거하지는 않았을 것입니다.
이 문제를 어떻게 해결할 수 있나요?
