升级到 Ubuntu 21.10 后 ZFS 数据集无法挂载

升级到 Ubuntu 21.10 后 ZFS 数据集无法挂载

所以我最近从 Ubuntu 21.04 升级到 21.10，现在我的 ZFS 数据集无法挂载，即使手动使用强制选项。

我尝试导出池并重新导入池，但即使使用强制选项尝试仍然失败。

root@daviserver:~# zfs mount -af
cannot mount 'ssdpool/sftpsync': Insufficient privileges
cannot mount 'ssdpool/sftpsync': Insufficient privileges
cannot mount 'ssdpool/docker': mount failed

syslog 显示以下内容，但我不确定这意味着什么。

Oct 17 13:19:21 daviserver kernel: [62900.992374] VFS: "mand" mount option not supported
Oct 17 13:19:21 daviserver kernel: [64689.402851] VFS: "mand" mount option not supported
Oct 17 13:19:21 daviserver kernel: [64689.402930] VFS: "mand" mount option not supported

我目前正在清理池以尝试修复所有错误。

root@daviserver:~# zpool status
  pool: ssdpool
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
    still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
    the pool may no longer be accessible by software that does not support
    the features. See zpool-features(5) for details.

我今天遇到了这个问题，dmesg 中也有同样的提示

在我的 SMB 服务器上，我记得有一个推荐的 zfs 选项用于 ZFS SMB 设置，名为恩布曼德用于非阻塞强制锁。所有无法挂载的 zpool 都启用了此选项。

sudo zfs get nbmand,mounted | grep -A1 ' on '

mountmand选项 已于 2021 年 8 月删除并进入 21.10 的内核，它应该被 mount 命令忽略，但 ZFS 的 mount 却没有。

Asudo zfs inherit nbmand $POOL && sudo zfs mount -a带回所有 zpools 和所有数据。
