今天想在pve里边通过zfs来开启nfs的共享 执行了命令 zfs set sharenfs=on zfspan/test 结果一直报错，从错误上一直没看出是什么原因

root@xxxx:~# zfs set sharenfs=on zfspan/test
cannot share 'zfspan/test': share(1M) failed
property may be set but unable to reshare filesystem

最后是发现是因为proxmox ve系统里边并没有安装nfs

安装命令如下：

root@xxxxx:~# apt install nfs-kernel-server
