[Ocfs2-users] FSCK may be failing and corrupting my disk???

[Eric Raskin]

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?
