如何实现seaweedfs卷服务器的高可用性？

Question

我在同一机架上有两台卷服务器。而我的复制是001，如果其中一个卷服务器已关闭，因为复制是001，因此上载功能将不可用。如何保证卷服务器的高可用？如果我修复了崩溃节点，数据会自动同步吗？如果是，在同步过程中，当请求进入时，请求是否会自动切换到另一个良好的节点。

我在同一个机架上运行了kubernetes中的卷服务器。其中一个pod总是重新启动。并且日志中没有明显的错误。

系统设置主程序：

/usr/bin/weed master -ip=weedfs-master -port=9333 -defaultReplication="001" -mdir=/data -volumePreallocate -volumeSizeLimitMB=1024
ports: - containerPort: 9333 args: - master - -ip=weedfs-master - -port=9333 - -defaultReplication="001" env: - name: TZ value: Asia/Hong_Kong

卷server1：

/usr/bin/weed volume -mserver=weedfs-master:9333 -max=500 -publicUrl=https://file-storage-exhibition.ssiid.com -ip=weedfs-volume-1 -port=8080 -rack=rack1 -dir=/data -max=0
ports: - containerPort: 8080 args: - volume - -mserver=weedfs-master:9333 - -max=500 - -publicUrl=https://file-storage-exhibition.ssiid.com - -ip=weedfs-volume-1 - -port=8080 - -rack=rack1 env: - name: TZ

卷server2：

/usr/bin/weed volume -mserver=weedfs-master:9333 -max=500 -publicUrl=https://file-storage-exhibition.ssiid.com -ip=weedfs-volume-2 -port=8080 -rack=rack1 -dir=/data -max=0
ports: - containerPort: 8080 args: - volume - -mserver=weedfs-master:9333 - -max=500 - -publicUrl=https://file-storage-exhibition.ssiid.com - -ip=weedfs-volume-2 - -port=8080 - -rack=rack1 env: - name: TZ

操作系统版本30 OS 1.75linux amd6

pods的日志总是以：

如何保证卷服务器的高可用性？

添加两个以上的卷服务器。

如果我修复了崩溃节点，数据会自动同步吗？

写入将失败。但是写请求应该从主服务器获得新的分配，并转到其他卷服务器进行写。不需要同步任何东西。
