서버를 재시작 하였을 때 gluster 데몬이 running이기 전에 마운트를 시도했다면,
위와 같은 현상이 나타날 수 있습니다.
문제 해결
- 마운트를 재시도 합니다.
/etc/fstab에 gluster mount 옵션이 작성되어 있을 것입니다.gluster 볼륨이 정상적으로 마운트 되었는지 확인합니다.cat /etc/fstab 192.168.50.177:/gluster-vol-devai /data/mnt/gluster/devai glusterfs defaults,_netdev 0 0 192.168.50.177:/gluster-vol-aiops /data/mnt/gluster/aiops glusterfs defaults,_netdev 0 0 192.168.50.177:/gluster-vol-aiops-build /data/mnt/gluster/aiops-build glusterfs defaults,_netdev 0 0 192.168.50.177:/gluster-vol-aiops-integrate /data/mnt/gluster/aiops-integrate glusterfs defaults,_netdev 0 0
위 옵션을 다시 읽어올 수 있도록 아래와 같이 수행합니다.mount -a
