Updated e2fsprogs packages that fix two bugs 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 second (ext2), third (ext3), and fourth (ext4) extended file systems.
Prior to this update, checksums for backup group descriptors appeared to be wrong when the "e2fsck -b" option read these group descriptors and cleared UNINIT flags to ensure that all inodes were scanned. As a consequence, warning messages were sent during the process. This update recomputes checksums after the flags are changed. Now, "e2fsck -b" completes without these checksum warnings.
Prior to this update, e2fsck could discard valid inodes when using the "-E discard" option. As a consequence, the file system could become corrupted. This update modifies the underlying code so that disk regions containing valid inodes are no longer discarded.
All users of e2fsprogs are advised to upgrade to these updated packages, which fix these bugs.
