GlusterFS 복제 볼륨 - 설치 문제

저는 2개의 서버(ST0 및 ST1)와 1개의 클라이언트(STC)로 GlusterFS를 실행하고 있으며 볼륨 이름은 rep-volume입니다.

인터넷을 검색하여 설치 문제를 해결하는 방법을 설명하는 모든 기사를 읽었지만 불행히도 아무것도 도움이 되지 않았습니다.

다음 명령을 처음 사용했을 때 제대로 작동했고 쓰기 권한이 있었습니다.

$ mount.glusterfs ST0:/rep-volume /mnt/replica/

하지만 클라이언트를 다시 시작한 후 다시 마운트할 수 없으며 결과는 다음과 같습니다.

$ mount.glusterfs ST0:/rep-volume /mnt/replica/
Mount failed. Please check the log file for more details.

로그 파일은 다음과 같습니다.

$ cat /var/log/glusterfs/mnt-replica.log

누구든지 나를 도울 수 있다면 매우 감사하겠습니다. 감사해요.

고쳐 쓰다:

@FarazX가 제공한 답변은 정말 도움이 되었고 내 문제를 해결했지만 클라이언트 서버에서 동일한 작업을 수행할 때(성공하지 못한 채) 왜 이것이 작동하는지 알아내는 데 여전히 관심이 있습니다. 나는 bugzilla.redhat.com에서 많은 내용을 읽었지만 그 이유는 여전히 나에게 다소 모호합니다.
