ERROR Unable to initialize backend: no locks available.

ERROR Unable to initialize backend: no locks available._报错信息

服务器做了nas共享存储后,修改minio的数据目录为nas共享目录,启动minio服务失败,报错信息如上图所示:

从这个日志来看,应该是minio拿不到nfs文件系统的锁。

解决方案

  1. nfs挂载时加nolock参数
  2. 使用nfsv4,而不是用nfsv3

参考

gitlab底层也是用的minio,gitlab官方文档是这么写的

File locking: GitLab requires advisory file locking, which is only supported natively in NFS version 4. NFSv3 also supports locking as long as Linux Kernel 2.6.5+ is used. We recommend using version 4 and do not specifically test NFSv3

总结

最后我们选择了方案2,但是Minio官网是推荐用nfsv4协议挂载,以上就是本篇博客的全部内容
