RHBA-2014:1203 - Bug Fix Advisory

Topic

Updated gfs2-utils packages that fix several bugs are now available for Red Hat
Enterprise Linux 5.

Description

The gfs2-utils packages contain utilities for creating, checking, modifying, and
correcting any inconsistencies in GFS2 file systems.

This update fixes the following bugs:

• Under rare circumstances, certain leaf blocks are written to the incorrect

index nodes. Thus, some directories have improper leaf blocks attached. In
certain cases, the fsck.gfs2 utility was unable to detect and repair this
corruption. With this update, a patch has been provided to fix this bug and
fsck.gfs2 now correctly detects and fixes the corruption. (BZ#902918)

• After the gfs2_grow, gfs2_tool, gfs2_jadd, or gfs2_quota utilities cleaned up

the /etc/mtab file, the file's permissions were changed from the default of 644
to 600. As a consequence, non-root processes could not read /etc/mtab. This
update fixes the code that cleans up the /etc/mtab file so that it no longer
modifies the /etc/mtab file's permissions. As a result, processes are able to
access the /etc/mtab file as expected. (BZ#1073384)

• Under certain circumstances, an attempt to use the gfs2_convert utility caused

the system to terminate unexpectedly with a segmentation fault. This update
provides a patch to fix this bug so that the system no longer crashes in the
described scenario. (BZ#1084140)

• Previously, the fsck.gfs2 utility did not log important context of system

events. Consequently, users and system administrators had difficulties examining
the circumstances under which a problem occurred. With this update, fsck.gfs2
adds an informative message to the system logs on its start and exit, which
helps in further debugging processes and administrative actions. (BZ#1097348)

• Previously, GFS2 metadata dumps returned by the "gfs2_edit savemeta" command

held no information about the time at which they were created. Without this
information, users and system administrators could not easily find out when the
GFS2 metadata was saved in relation to file system checks. With this update,
"gfs2_edit savemeta" adds a header to the metadata file containing a time stamp.
(BZ#1097349)

Users of gfs2-utils are advised to upgrade to these updated packages, which fix
these bugs.
