** Description changed: After you create a mkfs.ext4 filesystem, the new filesystem returns very high d_off values for all fs content. - I came across this problem using GlusterFS what utilizes the d_off values got so high that even in 64bit the values were overflowing gluster's transformed d_off causing a wrap around and readdir to loop. + I came across this problem using GlusterFS what utilizes the d_off values, they got so high that even in 64bit the values were overflowing gluster's transformed d_off causing a wrap around and readdir to loop. Originally discovery of the bug was on kernel 3.4.4, but as I report this it is still the case in 3.5.0-3-generic kernel. d_off listing of my ext4 fs: ..: 2296413350859310193 .: 4783779301059207147 lost+found: 5425848893403102488 test: 9223372036854775807 as a comparison I formatted the same disk with xfs, give these more normal d_off values .: 4 ..: 6 test: 512 ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: linux-image-3.5.0-3-generic 3.5.0-3.3 ProcVersionSignature: User Name 3.5.0-3.3-generic 3.5.0-rc5 Uname: Linux 3.5.0-3-generic x86_64 AlsaDevices: - total 0 - crw-rw---T 1 root audio 116, 1 Jul 9 08:48 seq - crw-rw---T 1 root audio 116, 33 Jul 9 08:48 timer + total 0 + crw-rw---T 1 root audio 116, 1 Jul 9 08:48 seq + crw-rw---T 1 root audio 116, 33 Jul 9 08:48 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.2.5-0ubuntu2 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CRDA: Error: [Errno 2] No such file or directory: 'iw' CurrentDmesg: [ 51.139794] EXT4-fs (vdb): mounted filesystem with ordered data mode.
