저는 2개의 서버(ST0 & ST1)와 1개의 클라이언트(STC)를 사용하여 GlusterFS를 실행하고 있으며 볼륨 이름은 rep-volume입니다.
나는 인터넷을 서핑하고 장착 문제를 해결하는 방법을 설명하는 모든 기사를 읽었지만 불행히도 아무것도 도움이 되지 않았습니다.
다음 명령을 처음 사용했을 때 완벽하게 작동했으며 쓰기 권한이 있었습니다.
$ mount.glusterfs ST0:/rep-volume /mnt/replica/
그러나 클라이언트를 재부팅한 후에는 다시 마운트할 수 없습니다. 결과는 다음과 같습니다.
$ mount.glusterfs ST0:/rep-volume /mnt/replica/
Mount failed. Please check the log file for more details.
로그 파일은 아래와 같습니다.
$ cat /var/log/glusterfs/mnt-replica.log

누구든지 나를 도울 수 있다면 매우 감사하겠습니다. 감사해요.
업데이트:
@FarazX가 제공한 답변은 정말 도움이 되었고 문제를 해결했지만 클라이언트 서버에서 동일한 작업을 수행하는 동안(성공하지 못한 채) 이 조건이 작동한 이유를 찾는 데 여전히 관심이 있습니다. 나는 bugzilla.redhat.com에서 많은 내용을 읽었지만 그 이유는 여전히 나에게 다소 모호합니다.
답변1
저도 같은 문제가 있었지만 동일한 서버에 클라이언트를 마운트하려고 시도했는데 완벽하게 작동했습니다.
귀하의 경우 ST0 및 ST1에서 각각 다음 명령을 실행하면 됩니다.
ST0: ~ root # mkdir /mnt/replica
ST0: ~ root # mount.glusterfs ST0:/rep-volume /mnt/replica/
ST0: ~ root # echo 'ST0:/rep-volume /mnt/replica glusterfs _netdev,fetch-attempts=10 0 0' >> /etc/fstab
&
ST1: ~ root # mkdir /mnt/replica
ST1: ~ root # mount.glusterfs ST1:/rep-volume /mnt/replica/
ST1: ~ root # echo 'ST1:/rep-volume /mnt/replica glusterfs _netdev,fetch-attempts=10 0 0' >> /etc/fstab
주의방화벽 구성 및 규칙을 확인하세요.
이것이 귀하의 문제를 해결할 수 있기를 바랍니다.
