奇怪的是,这上周发生在我的两个节点上,但是当我再次启动它们时,第一个节点工作正常,而第二个节点出现此错误。

我正在使用

ctdb event script enable legacy 50.samba

这是我的 smb.conf

[global]
        workgroup = WORKGROUP2
        clustering = yes
        netbios name = gluster
        idmap backend = tdb2

[share]
        path = /mnt/gfs/share
        valid users = fsuser
        readonly = no
        browsable = yes

我正在运行带有最新 ctdb 和 samba 的 ubuntu server 19.10。共享文件系统是 glusterfs,该部分运行正常,并通过了 ping_pong 测试。

我也使用 journalctl -b 看到了此消息

答案1

pstree 输出表明“service nmbd start”在尝试执行 systemd 操作时挂起。

如果您在终端中尝试“service nmbd start”,会发生什么情况?“systemctl start nmbd”怎么样?

答案2

我找到了一个解决方法。我禁用 ctdb samba 旧脚本并使用常规 systemctl 启动脚本。

sudo systemctl edit ctdb

添加以下内容并保存退出

[Unit]
Require=mnt-gfs.mount
After=mnt-gfs.mount

要找出您的 .mount,您可以运行此命令并使用您的 glusterfs 或其他分布式文件系统挂载点切换挂载补丁。

sudo systemctl list-units | grep '/mnt/gfs' | awk '{ print $1 }'

然后只需编辑 smbd 和 nmbd 服务文件即可。

sudo systemctl edit smbd.service
sudo systemctl edit nmbd.service

然后将其添加到上述两个文件中,保存并退出

[Unit]
After=ctdb.service

确保 ctdb 已启动并正在运行,然后运行此命令(如果未运行,请使用 systemctl start ctdb 启动它)

sudo ctdb event script enable legacy 50.samba

重新启动您的节点,它应该会挂载您的分布式文件系统共享,启动 ctdb,然后启动 smbd 和 nmbd。
