LV 쓰기 액세스 읽기/쓰기(읽기 전용 활성화) 문제

저는 Centos 7 64비트를 사용하고 있습니다.

다음 오류가 발생합니다.

Sep  7 10:03:11 nginx kernel: Buffer I/O error on device dm-8, logical block 18989734

그리고

Sep  7 13:07:38 nginx kernel: EXT4-fs error (device dm-8): htree_dirblock_to_tree:915: inode #4194380: block 16785475: comm qmgr: bad entry in directory: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0, size=4096

그리고

내 pool00_tmeta 파티션에 읽기 전용 액세스 권한이 있음을 확인했습니다.

이 명령을 사용하여 rw로 만들려고 시도했지만 작동하지 않습니다.

 lvchange -prw -ay centos/pool00
  Command on LV centos/pool00 uses options invalid with LV type thinpool.
  Command not permitted on LV centos/pool00.

이것은 내 파티션입니다.

이것은 /etc/fstab입니다

vmware는 어렵네요

OS를 재부팅할 때 CTRL+D를 보내 부팅해야 합니다.
