| |
We have a EXT3 filesystem contained in a file (a disk image mapped to a file using loop device). Using diff, observed random differences between files on the image and a backup copies of those files. This problem is reproducible, tried booting several times with 3.3.8 and 3.4.0. No problems on 3.3.8. But every time on 3.4.0, randomly a few files showed corruption. Some files that were corrupt become ok again after rebooting/remounting. About 5% of the file contents was garbage, rest was correct, the file size was correct.
Seems to be a memory problem in 3.4.0? chkdsk never showed any problem (in the disk image file).
Using Debian 6. Ran memtest86+, chkdsk, badblocks -- no errors. Disk image was created mkfs.ext3 with the smallest inode/block size. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
