Hi Akira, thanks for reporting this. Could you please try to use the most recent e2fsprogs ? The EOFBLOCKS_FL has been removed from e2fsprogs with: 010dc7b90d97b93907cbf57b3b44f1c1cad234f6 e2fsck: remove EXT4_EOFBLOCKS_FL flag handling and is about to be removed from kernel as well, so the EOFBLOCKS_FL problem probably does not even matter. Though the i_size problem might be real. Not sure if it is a known problem, but I've certainly seen it before with xfstest 269, though I have not had time to look at this yet. So I guess I should :).

Because the last uninitialized extent (~~~ in below) whose offset exceeds i_size and is not checked with the latest e2fsck. # debugfs: stat <1237> Inode: 1237 Type: regular Mode: 0666 Flags: 0x80000 Generation: 2257700857 Version: 0x00000000:00000001 User: 1870 Group: 1899 Size: 440021 File ACL: 0 Directory ACL: 0 Links: 1 Blockcount: 256 Fragment: Address: 0 Number: 0 Size: 0 ctime: 0x5007a2a0:ee09d6a0 -- Thu Jul 19 15:01:04 2012 atime: 0x5007a2ae:7dbe4e64 -- Thu Jul 19 15:01:18 2012 mtime: 0x5007a2a0:ee09d6a0 -- Thu Jul 19 15:01:04 2012 crtime: 0x5007a283:31ed0abc -- Thu Jul 19 15:00:35 2012 Size of extra inode fields: 28 EXTENTS: (12-38):49820-49846, (106):13714, (107):41292, (108-110[u]):41293-41295 ~~~~~~~~~~~~~~~~~~~~~~~~ Regards, Akira Fujita (2012/07/18 18:40), Lukáš Czerner wrote: > On Wed, 18 Jul 2012, Akira Fujita wrote: > >> Date: Wed, 18 Jul 2012 16:58:11 +0900 >> From: Akira Fujita <a-fujita@rs.jp.nec.com> >> To: Theodore Tso <tytso@mit.edu> >> Cc: ext4 development <linux-ext4@vger.kernel.org> >> Subject: [BUG] ext4: i_size, EOFBLOCKS_FS corruption with xfstests 269 >> >> Hi, >> >> I got a issue which makes i_size and EOFBLOCKS_FL corrupted >> on ext4 with xfstests 269. >> In my environment (linux-3.5-rc7), this can be reproduced >> once of 10 times trial. >> >> Kernel: 3.5-rc7 >> Arch: x86_64 >> >> Step and log are as bellow, after xfstests 269, e2fsck outputs >> i_size and EOFBLOCKS_FL corruption. >> Is this an already known issue? > > Hi Akira, > > thanks for reporting this.
