我昨天晚上调整了硬盘的大小，并没有成功。
我的系统和驱动器在ESXi 5.1 vm上是本地的。
我正在运行Debian 6 x64并有一个2TB的安装，我正在调整。 大约1.8T，我正在调整到全2TB。
我在/ dev / sdc1上运行了e2fsck，没有问题。 我比运行resize2fs，让它运行几个小时。 在检查ps后，它显示睡眠状态（D +）没有活动。 我不能杀死进程，所以我重新启动，现在我无法对驱动器做任何事情。
现在我错过了/ dev / sdc1驱动器，我什么也读不了， fdisk，cfdisk，e2fsck，resize2fs都冻结，试图做任何与这个驱动器有关的事情。
我能做些什么来恢复这个驱动器？ 我不幸没有这个驱动器的备份。 我只是想能够挂载驱动器来恢复我的数据，或至less读驱动器上的数据莫名其妙。

如果你在运行的时候中断了它，这是丢失你所有数据的好方法。 所有的文件系统数据结构都可能处于不一致的状态。
现在，您的驱动器在分区表存储位置的磁盘开始处有错误。
在这一点上，你应该做的是更换磁盘并恢复你的备份。 由于你没有备份，你应该更新你的简历。 如果这台服务器非常重要，公司可能会倒闭。
为了避免将来出现这种情况，请务必确保备份完成，并且备份function完全正常，可以成功恢复。
所以，除了更新你的简历和备份之外，这是你今天需要做的事情：
您可以尝试使用dd_rescue将该磁盘复制到另一个磁盘，然后从该副本中恢复数据。
不过，不要指望太多。
如果您无法从磁盘上拯救任何东西，请将其发送给专业的数据恢复公司。
我知道这是几年后，对OP没有任何帮助，但我想为这个post中的其他人添加另一个视angular。
我有resize2fs中断不止一次（即电源故障），并在快速fsck之后没有任何问题或数据丢失。 这种方式丢失大量的数据当然听起来似乎是合理的，甚至会破坏整个分区，因为这影响了文件系统本身，我从来没有亲眼目睹过它。
但是，OP发布的错误与尝试运行dd_rescue （不关心文件系统级别的损坏）的失败尝试指向了硬件故障（或者在VM的情况下，容器文件有问题，或者底层硬件）。 虽然巧合，这听起来独立于失败的resize2fs尝试。
我首先要确保底层硬件是好的。 如果所有检查都在那里，请复制VM映像，然后重新生成副本（具体方法取决于映像格式）。 最后，启动副本，运行fsck ，看看是否能解决问题。
