Chris, I have no way to test this, because I no longer have a filesystem with multiply-claimed blocks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1321418 Title: fsck.ext4 fails to fix

Hi Theodore, thanks for your really fast answer. I do not know how to get fsck version number, but I had the following output: fsck from util-linux 2.20.1 e2fsck 1.42 (29-Nov-2011) However I have run `e2fsck f_dup5.img` on your attachment at #6, and no error was reported, so I do not know

[Bug 1321418] Re: fsck.ext4 fails to fix multiply-claimed blocks: can't find dup_blk

The file system which I posted in #6 no longer triggers a bug in 1.42.12. It looks like it was fixed as a side effect of commit 9a1d614df217. @bigeel, what version of e2fsck were you using? Could you try using e2fsprogs 1.42.12 and see if that fixes the problem for you? Thanks!! -- You

Hi, I had the same error message doing while fsck'ing one of my disks. I did not understand well the cause of the problem. Is fsck what caused the file-system corruption? (because of an extent-mapped inode getting written (or copied) to a different/wrong place in the inode table?) This ticket is

Right, I didn't notice the first time I read the bug report you had already deleted the inode to fix the problem. It would have been nice to have gotten a look at the inode in question so I could really see what was going on. The internal error: can't find dup_blk error is one of those this

Thanks, I was able to reproduce the problem using a test file system. The problem appears to have been caused by an extent-mapped inode getting written (or copied) to a different/wrong place in the inode table. I should be able to get this fixed now that I have a simple repro. ** Changed in:
