  1. 2011.11.23 samba에 갑작스러운 "엑세스 거부"
서버운영이 1년을 넘어가니 별별 문제가 다 생기는데 흐음.. 

/etc/samba/smb.conf 에서 mask를 바꾸고는
chown 명령으로 퍼미션을 바꾸어 주려는데 아래와 같이 Read-only라고 배를 짼다 -_-
 unable to chmod /home/samba/sharedDocs/ : Read-only file system 

mount 명령으로 확인해도 /dev/sda rw 인데
혹시나 해서 다시 마운트 하게 해도 에러가 발생한다 -_-
 $ sudo mount -o remount,rw /dev/sda

dmesg를 해보니 헐...

rw라고 나오지만 실제로는 ro로 강제 변경당했다 -_-
fsck 해보라는데 으아아.. fsck 돌렸다가 하드 날린적이 있어서 겁나는디 -_-
