라즈베리파이 File system check failed 문제

아침부터 라즈베리를 키는데 갑자기 에러가 출력되었다.

fsck: Warning... fsck.vfat for device /dev/mmcblk0p1 exited with signal6.

fsck died with exit satus 8

failed (code 8).

[FAIL] File system check failed. A log is being saved in /var/log/fsck/ckeckfs ~~

에러 로그 확인

급한마음에 막 unmount하지 않고 sd카드리더기에서 빼고 그랬는데 문제가 생겼나보다..

해결방법

https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=53365 참고

$ sudo dosfsck -w -r -l -a -v -t /dev/mmcblk0p1

본인의 경우(sudo dosfsck -w -r -l -a -v -t /dev/sdb1)

결과값

dosfsck이란 (MAN 참고)

MS-DOS 파일 시스템을 체크하고 수리하기 위함

Synopsis

dosfsck [-aAflrtvVwy] [-d path -d ...] [-u path -u...] device

Options

-a Automatically repair the file system. No user intervention is

              necessary.   Whenever  there  is more than one method to solve a
              problem, the least destructive approach is used.

       -A     Use Atari variation of the MS-DOS filesystem. This is default if
              dosfsck  is  run  on  an Atari, then this option turns off Atari
              format. There are some minor differences in Atari  format:  Some
              boot  sector  fields are interpreted slightly different, and the
              special FAT entries for end-of-file and bad cluster can be  dif-
              ferent.  Under  MS-DOS  0xfff8 is used for EOF and Atari employs
              0xffff by default, but both systems recognize  all  values  from
              0xfff8...0xffff as end-of-file.  MS-DOS uses only 0xfff7 for bad
              clusters, where on Atari values  0xfff0...0xfff7  are  for  this
              purpose (but the standard value is still 0xfff7).

       -d     Drop  the  specified  file. If more that one file with that name
              exists, the first one is dropped.

       -f     Salvage unused cluster chains to files. By default, unused clus-
              ters  are added to the free disk space except in auto mode (-a).

       -l     List path names of files being processed.

       -r     Interactively repair the file system.  The  user  is  asked  for
              advice whenever there is more than one approach to fix an incon-
              sistency.  This is the default behaviour.

       -t     Mark unreadable clusters as bad.

       -u     Try to undelete the specified file. dosfsck tries to allocate  a
              chain  of  contiguous  unallocated  clusters  beginning with the
              start cluster of the undeleted file.

       -v     Verbose mode. Generates slightly more output.

       -V     Perform a verification pass. The file system check  is  repeated
              after  the  first  run.  The second pass should never report any
              fixable errors. It may take considerably longer than  the  first
              pass,  because  the  first  pass may have generated long list of
              modifications that have to be scanned for each disk read.

       -w     Write changes to disk immediately.

       -y     Same as -a (automatically repair filesystem)  for  compatibility
              with other fsck tools.

       If  -a  and  -r  are  absent,  the file system is only checked, but not
       repaired.
