![服务器重启后卷安装问题](https://linux22.com/image/788568/%E6%9C%8D%E5%8A%A1%E5%99%A8%E9%87%8D%E5%90%AF%E5%90%8E%E5%8D%B7%E5%AE%89%E8%A3%85%E9%97%AE%E9%A2%98.png)
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:
root@bkp-01:~# cat /etc/fstab
# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

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:
Backup [Test] /usr/bin/rsync -a "rsync://10.11.11.195/encrypted" "/storage/backups/Test/" failed with rc 11 rsync: mkdir "/storage/backups/Test" failed: No such file or directory (2) rsync error: error in file IO (code 11) at main.c(674) [Receiver=3.1.1]
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
passfile=/root/tmp-pass-revitalis.txt
和
root@bkp-01:~# mount /storage/mount-revitalis
Attempting to mount with the following options:

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!
