RHBA-2013:1641 - Bug Fix Advisory

Topic

Updated glusterfs packages that fix several bugs and add one enhancement are now
available for Red Hat Enterprise Linux 6.

Description

Red Hat Storage is software only, scale-out storage that provides flexible and
affordable unstructured data storage for the enterprise. GlusterFS, a key
building block of Red Hat Storage, is based on a stackable user-space design and
can deliver exceptional performance for diverse workloads. GlusterFS aggregates
various storage servers over network interconnects into one large, parallel
network file system.

This update fixes the following bugs:

• Previously, the "errno" value was not set correctly during an API failure.

Consequently, applications using API could behave unpredictably. With this
update, the value is set properly during API failures and the applications work
as expected. (BZ#998778)

• Previously, the glusterfs-api library handled all signals that were sent to

applications using glusterfs-api. As a consequence, glusterfs-api interpreted
incorrectly all the the signals that were not used by this library. With this
update, glusterfs-api no longer handles the signals that it does not use so that
such signals are now interpreted properly. (BZ#998832)

• Previously, the glfs_fini() function did not return NULL, even if the libgfapi

library successfully cleaned up all resources. Consequently, an attempt to use
the "qemu-img create" command, which used libgfapi, failed. The underlying
source code has been modified so that the function returns NULL when the
libgfapi cleanup is successful, and the command now works as expected.
(BZ#1017014)

In addition, this update adds the following enhancement:

• Native Support for GlusterFS in QEMU has been included to glusterfs packages.

This support allows native access to GlusterFS volumes using the libgfapi
library instead of through a locally mounted FUSE file system. This native
approach offers considerable performance improvements. (BZ#916645)

Users of glusterfs are advised to upgrade to these updated packages, which fix
these bugs and add this enhancement.
