当我尝试挂载一个现有的磁盘时，我收到消息
sudo mount -t ext4 /dev/sdc1 /data mount: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so 当我看着dmesg ，我明白了
[ 707.504050] EXT4-fs (sdc1): group descriptors corrupted!
然后我运行命令

问题：当我尝试重新安装它，这次是成功的，但只显示空的分区，只有lost+found文件夹，我的100GB分区变成29GB。
任何想法？
你的文件系统变得绝望了， e2fsck可以做些什么来保存是不够的。 消灭FS并从备份恢复。 我会添加“ 考虑更换硬件 ”，除了你上面发布的内容，这表明这是一个虚拟服务器。
在回答上面的评论时，你所做的几乎是我们所有人都可以在FS发生的情况下（FS内核的黑客，可能能够使用debugfs ）除外。 不要责怪自己 – 除非你没有任何备份，在这种情况下，要责备自己，并学习重要的一课。
