Samba 共享上的 Time Machine 备份失败，出现错误 512、20 和 14

我已经按照以下说明设置了 Samba 共享，用于 Time machine 备份本指南。

我的 Mac 正确识别共享，但初始备份失败，并显示无法在我的共享上创建备份的通用错误消息。

运行log stream --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --info后出现如下日志：

奇怪的是：与日志相反，一个名为 的稀疏束74F8F302-361C-4490-9E35-1F2598F9D16E/A76BCEEB-A3BD-5D63-82F4-8AEBB2F5ACBA.sparsebundle实际上在我的共享中创建。因此写入权限肯定不是问题。

macOS 10.14.1 Samba 4.8.0

答案1

事实证明，我尝试的配置不适用于 HFS+ 格式的驱动器。使用 ext4 重新格式化驱动器可消除错误，因此备份实际上可以开始。
