Is there a way to run fsck when boot failed? #2104

Sometimes the VM failed to boot because of the filesystem crashed. Currently I have to delete the diffdisk and create a new instance, but there maybe some important data I want to keep. How can I run the fsck for the diffdisk to fix? |

Hmm, maybe it would need some kind of emergency disk But I guess in the long run one would have to put important data on a separately created data disk. So that it can be mounted again, after the os disk has been recreated... |
