7.46. e2fsprogs

Updated e2fsprogs packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
The e2fsprogs packages provide a number of utilities for creating, checking, modifying, and correcting any inconsistencies in the ext2 file systems.

Bug Fixes

BZ#806137
On a corrupted file system, the "mke2fs -S" command could remove files instead of attempting to recover them. This bug has been fixed; the "mke2fs -S" command writes metadata properly and no longer removes files instead of recovering them.
BZ#813820
The resize2fs(8) man page did not list an ext4 file system as capable of on-line resizing. This omission has been fixed and the resize2fs(8) man page now includes all file systems that can be resized on-line.
BZ#858338
A special flag was used to indicate blocks allocated beyond the end of file on an ext4 file system. This flag was sometimes mishandled, resulting in file system corruption. Both the kernel and user space have been reworked to eliminate the use of this flag.

Enhancement

BZ#824126
Previously, users could use the e2fsck utility on a mounted file system, although it was strongly recommended not to do so. Using the utility on a mounted file system led to file system corruption. With this update, e2fsck opens the file system exclusively and fails when the file system is busy. This behavior avoids possible corruption of the mounted file system.

Bug Fix

BZ#1023351
The resize2fs utility did not properly handle resizing of an ext4 file system to a smaller size. As a consequence, files containing many extents could become corrupted if they were moved during the resize process. With this update, resize2fs now maintains a consistent extent tree when moving files containing many extents, and such files no longer become corrupted in this scenario.

Bug Fix

BZ#974193
Some ext4 extent tree corruptions were not detected or repaired by e2fsck. Inconsistencies related to overlapping interior or leaf nodes in the extent tree were not detected, and the file system remained in an inconsistent state after an e2fsck. These inconsistencies were then detected by the kernel at run time. e2fsck is now able to detect and repair this class of corruptions in the file system.
