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? # ./check 269 FSTYP -- ext4 PLATFORM -- Linux/x86_64 mcds1 3.5.0-rc7 MKFS_OPTIONS -- /dev/sdb3 MOUNT_OPTIONS -- -o acl,user_xattr /dev/sdb3 /mnt/mp2 269 97s ...
