I find generic/269 fails on ext4 because of i_blocks corruption like e2fsck 1.42.12 (29-Aug-2014) Pass 1: Checking inodes, blocks, and sizes Inode 4802, i_blocks is 280, should be 248. Fix? no Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information ext4.img: ********** WARNING: Filesystem still has errors ********** ext4.img: 32752/32768 files (12.0% non-contiguous), 128483/131072 blocks and find that it has something to do with the setattr and write operations in fsstress, with delalloc enabled. This can be reproduced more reliably by # disable all other operations except create/mkdir/write/setattr # the "-M 524288" restricts the setflags ioctl to EXT4_EXTENTS_FL export FSSTRESS_AVOID="-fallocsp=0 -fattr_remove=0 -fattr_set=0 \ -fbulkstat=0 -fbulkstat1=0 -fchown=0 -fdread=0 -fdwrite=0 \ -ffallocate=0 -ffiemap=0 -ffreesp=0 -fgetattr=0 -fgetdents=0 \ -flink=0 -fmknod=0 -fpunch=0 -fzero=0 -fcollapse=0 -finsert=0 \ -fread=0 -freadlink=0 -frename=0 -fresvsp=0 -frmdir=0 -fsetxattr=0 \ -fstat=0 -fsymlink=0 -ftruncate=0 -funlink=0 -funresvsp=0 \ -fsetattr=5 -M 524288" while ./check generic/269; do : ; done And a simplified reproducer is xfs_io -fc "pwrite 4k 4k" -c "fsync" /mnt/ext4/testfile chattr -e /mnt/ext4/testfile xfs_io -c "pwrite 0 4k" /mnt/ext4/testfile umount /mnt/ext4 e2fsck -nf /dev/<device> More details please see the commit log in patches.
