树莓派Raspberry Pi 4B部署NFS时报错

系统是官方烧录器烧的Raspberry OS 64bit armv7
基本上流程是按照这个流程走的写好/etc/exports后执行sudo service nfs-server start服务起不来总是失败根据提示sudo journalctl -xe后看到以下内容

乍一看是几个dependency错误但往上看能看到是proc-fs-nfsd.mount启动失败。

TL;DR

重启解决问题

$ reboot

解决方案来自Raspberry Pi Forums

已经尝试过的解决方案对我无效但可能能帮到你

以下是我在搜索这个错误时遇到的一些解决方案但他们和我遇到的问题不同但可能是你的问题所以建议都看看

• Dependency错误journalctl -xe指出network manager wait online未启动netctl-wait-online/ArchWiki
• 看日志时发现自己不小心干掉了/被干掉了/usr/bin目录nfs4-server doesn’t work/ArchWiki
• proc-fs-nfsd.mount: Mount process exited, code=exited status=32上面日志显示mount: /proc/fs/nfsd: nfsd already mounted on /proc/fs/nfsd.即mount一个已经被mount过的目录Dependency failed for NFS server and services
• 试图在容器里起NFS服务会失败因为NFS需要内核支持这也是Windows 10 家庭版怎么也起不来NFS的原因Can’t start NFS Server
• 一个ODroidH2上的问题NFS Server Issue on ODriod H2
