I did some more research by running a fsck -fn. Basically it is one inode that is wrong and needs to be cleared. Is there a way to do that via debugfs? If I can delete that one inode, then all the doubly-linked clusters will not be doubly linked any more and all of the errors will go away.
Isn't that quicker than cloning a bad inode? On 03/22/2014 09:40 PM, Sunil Mushran wrote: > Cloning the inode means inode + data.
