freebsd 11 中的 zfs 空间中的 jails 会出现 mount descfs 错误

晚安，我正在尝试在 OVH 专用服务器上使用 freebsd 11 部署多监狱环境。

我创建了克隆的接口并创建了监狱，但是当我尝试启动时，它告诉我无法挂载 nullfs。

我将其添加到 /boot/loader.conf

nullfs_mount=1

重新启动，但现在出现第二个错误

Starting jails: cannot start jail  "haproxy": 
mount: .: Operation not supported by device
jail: haproxy: /sbin/mount -t fdescfs . /local/jails/haproxy/dev/fd: failed

我应用了

https://lists.freebsd.org/pipermail/freebsd-stable/2014-August/079700.html

并位于此处

应用此命令

#patch /sys/fs/fdescfs/fdesc_vfsops.c sys_fs_fdescfs_fdesc_vfsop

但它失败了，就像这样：

有人在 Freebsd 11 中发现这个错误吗？有人可以帮助我吗？提前谢谢了。

答案1

这个补丁是两年前针对 10.x 的，你现在将它应用到 11.x，难怪它会失败。你应该要求作者将它移植到 11.x，并且可能调查为什么它一开始没有提交到树中 - 我确信它有它不这样做的原因。

PS SO似乎不适合提出这个问题，合适的地方是freebsd-稳定版@邮件列表。
