GPFS 관리노드 와 계산노드간 용량이 맞지 않는 경우

GPFS 관리노드 와 계산노드간 용량이 맞지 않는 경우

 

# 관리서버 /data 용량
[root@mgmt ~]# df -h | grep "/data"
data            3.0P  2.5P  528T  83% /data

#계산노드 /data 용량
[root@node ~]# df -h | grep "/data"
data            3.0P  2.7P  295T  91% /data


# 해결방법 
- 관리서버와 계산노드간 /data 동기화(sync)가 되지 않아서 동기화(sync)를 맞춰줘야 함. mmdf /data 명령어를 수행하여 동기화 시켜주면 됨.
