【问题描述】:
我想为 sqlite db 存储使用 gluster 复制卷 但是,当 '.db' 文件更新时,LINUX 不会检测到更改,因此砖块之间的同步是不可能的。
有没有办法强制同步? 即使您使用 gluster volume repair 命令,它也不会同步。
<我的 Gluster 卷状态>
[root@be-k8s-worker-1 common]# gluster volume create sync_test replica 2 transport tcp 10.XX.XX.X1:/home/common/sync_test 10.XX.XX.X2:/home/common/sync_test
Replica 2 volumes are prone to split-brain. Use Arbiter or Replica 3 to avoid this. See: http://docs.gluster.org/en/latest/Administrator%20Guide/Split%20brain%20and%20ways%20to%20deal%20with%20it/.
Do you still want to continue?
(y/n) y
volume create: sync_test: success: please start the volume to access data
[root@be-k8s-worker-1 common]# gluster volume start sync_test
volume start: sync_test: success
[root@be-k8s-worker-1 sync_test]# gluster volume status sync_test

[root@be-k8s-worker-1 sync_test]# ls -al ## client 1

## diff -> No result
[root@be-k8s-worker-1 user]# diff sync_test/test.db sync_test2/test.db
但是如果我在 Windows 中比较相同的文件 compare on windows
