最初在 bkp-01 实例上。服务器和磁盘已手动设置为不同的可用区域。磁盘正在运行 zfs 进行备份/快照。这是一台旧服务器，手动突袭系统。
现在我们检查一下：

# /etc/fstab: static file system information.

现在如果我们检查可用磁盘空间
服务器重启后我们有：
root@bkp-01:~# zfs list
no datasets available
root@bkp-01:~# zpool status
no pools available
此备份错误在日志中显示为：

我们尝试了 ：
mount /storage/mount-revitalis
output
/storage/backups/revitalis /storage/mount-revitalis ecryptfs ecryptfs_cipher=aes,ecryptfs_key_bytes=32,key=passphrase:passfile=/root/tmp-pass-revitalis.txt,ecryptfs_passthrough=n,no_sig_cache,ecryptfs_enable_filename_crypto=n,noauto 0 0

和
root@bkp-01:~# mount /storage/mount-revitalis

发生这种情况的原因是：最初有一个带有 RAIDZ1 vdevs 的 ZFS 池“存储”，重新启动后，ZFS 池完全丢失，并且由于缺少挂载点而导致备份失败？
重新创建 ZFS 池和重新创建数据集有帮助吗？
任何帮助都将不胜感激！
