search for: fsfuzzer

...stem with different features and options, then adds corruption from both random data and copying parts of the filesystem internally to some other part of the filesystem. It might be useful to corrupt some random bits and bytes in the filesystem also, but it doesn't do that today. There is also fsfuzzer, which writes random data to the filesystem and tries to mount it, but I don't know if that has been tried with e2fsck. The other major question I have is why you are trying to create a new proprietary filesystem? That is really a ten year effort, and you would be much better off to use one...

Hi - I'm searching for file system corruption tool, say it inject disk-errors like multiply owned blocks etc. Later an integrity scan process (like e2fsck) will verify on-disk layout and fix these errors. I'd like to read/understand such tools before writing one for an proprietary on-disk file system. Do we have such tools for ext{2,3,4}fs ? Thanks for any help or pointers! -- ----

Hi, when mounting an intentionally corrupted btrfs filesystem i get the following warning and bug message.
