Message-ID: <CAFepXZhPc0Vw-m0h_U9SnS6=CutOsGbiApe=-PEbKb3dxWOEvw@mail.gmail.com> Date: Mon, 30 Jul 2012 21:53:15 -0500 From: Nick Semenkovich <semenko@...m.mit.edu> To: linux-ext4@...r.kernel.org Subject: "Unknown code" error when enabling metadata_csum on ext4 raid1 device I'm trying to enable metadata_csum on an ext4 raid1 device, but end up with a semi-cryptic error. (This is probably the same thing Tomasz Chmielewski reported in http://www.spinics.net/lists/linux-ext4/msg33139.html ) Is this issue being tracked someplace? $ uname -ar Linux dev 3.5.0-6-generic #6-Ubuntu SMP Mon Jul 23 19:52:14 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ git clone git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git $ ./configure [snip] $ make progs [snip] $ sudo misc/tune2fs -O metadata_csum /dev/md1 tune2fs 1.42.3 (14-May-2012) rewrite_directory: Unknown code Ijv 64 while rewriting directories The error code changes when I re-run tune2fs (to [a-zA-Z]*3 64). I've tried this on the master, "next", & "pu" git branches, all with errors. $ debugfs -R 'stats' /dev/md1 > http://web.mit.edu/semenko/Public/debugfs-md1.txt Best, Nick -- Nick Semenkovich Laboratory of Dr. Jeffrey I.
