Message-ID: <20170629234816.werual2uikyhc56k@thunk.org> Date: Thu, 29 Jun 2017 19:48:16 -0400 From: Theodore Ts'o <tytso@....edu> To: Ross Zwisler <ross.zwisler@...ux.intel.com> Cc: linux-ext4@...r.kernel.org Subject: Re: mkfs.ext4 -D option fails to mount I'm not able to reproduce it using your reproduction receipe using e2fsprogs 1.43.4. I suspect you might be hitting a bug which was fixed by this commit: commit d6cad379eb6c86ca58bf5b83a586577de412a2e6 Author: Theodore Ts'o <tytso@....edu> Date: Sun Sep 11 00:25:48 2016 -0400 libext2fs: fix unaligned, multiblock writes in the unix_io handler The read-modify-write code for the unaligned fallback code wasn't working for multi-block writes. This was unmasked by FreeBSD 11-rc2, since its malloc() is returning unaligned memory regions for large memory regions. Signed-off-by: Theodore Ts'o <tytso@....edu> Can you retry with e2fsprogs 1.43.4 and see if it fixes your issue? - Ted
