我进行了一次循环检查：

# ploop check -f /vz/private/192/root.hdd/root.hdd

这修复了其中一个：

ploop check -F /vz/private/183/root.hdd/root.hdd
ploop mount /vz/private/183/root.hdd/DiskDescriptor.xml
fdisk -l /dev/ploop32942
e2fsck /dev/ploop32942p1

然而，其中一个之后我在启动时得到了这个：

# vzctl start 183
Dump file /vz/dump/Dump.183 exists, trying to restore from it

失败后，当我尝试再次启动容器时，我必须再次执行 e2fsck 操作，但尝试再次启动它时出现同样的问题。

编辑3：

可能是因为磁盘是 GPT，所以 fsck 无法正常工作？

硬件重启后，以下建议的解决方案帮助逐个启动失败的容器：

# ploop check -F /vz/private/139/root.hdd/root.hdd
# ploop mount /vz/private/139/root.hdd/DiskDescriptor.xml
# fdisk -l /dev/ploop56824
# e2fsck /dev/ploop56824p1
# vzctl start 139

Dump file /vz/dump/Dump.131 exists, trying to restore from it

谢谢，帮助很大！

我会让其他人来回答，他们可能在这个问题上有比我更好的想法，但是在 umount、mount、start、重复之后运行了几次 e2fsck... 我终于设法将所有容器重新启动了。

事实上，我认为您可以跳过卸载过程，因为一个过程立即启动了，但我忘记将其卸载了。
