[linux] NFS 마운트 후 하위 폴더 추가 방법

이미 걸려있는 NFS에 폴더를 추가할일이 생겼다.

폴더를 추가해보자.

원본 NFS 서버에서 아무리 폴더를 생성했다 하더라도 마운트 되어있는 서버에 반영이 되질 않는다.

 

원본 NFS서버

[root@gdcfile01 pds]# vi /etc/exports
/pds/golden 192.168.52.78(rw,sync,no_root_squash)
/pds/golden 192.168.52.80(rw,sync,no_root_squash)
/pds/giocapital 192.168.52.80(rw,sync,no_root_squash)
/pds/test 192.168.52.80(rw,sync,no_root_squash)

80서버에 추가한 test디렉터리를 지정.

[root@gdcfile01 pds]# exportfs -r <-- 설정한 exports를 리빌드

 

 

NFS 마운트 되어있는 서버

[root@gdcwas03 /]# mount -t nfs -o remount,rw gdcfile01:/pds/ /pds/
[root@gdcwas03 /]# cd /pds
[root@gdcwas03 pds]# ll
total 80
drwxr-xr-x    2 crizen web  4096 2021-12-09 16:52 giocapital
drwxr-x--x 2312 crizen web 69632 2021-12-10 08:53 golden
drwxr-xr-x    2 crizen web  4096 2021-12-10 14:04 test

추가 완료.

 

** 상위 폴더를 마운트하면 하위폴더가 보여짐, exports 설정에서 절대경로로 지정해두면 지정된 폴더만 보여짐.
