RHBA-2012:0277 - Bug Fix Advisory

Topic

Updated gfs-kmod packages that fix two bugs are now available for Red Hat
Enterprise Linux 5.

Description

The gfs-kmod packages contain kernel modules that provide the ability to mount
and use the Global File System (GFS).

This update fixes the following bugs:

• Previously, the directory pre-fetching GFS functionality could decrease

performance of some applications that were running on the GFS file system. This
update introduces a new GFS mounting option, "-o noprefetch", which disables the
directory pre-fetching feature. The applications running on the GFS file system
mounted with this option no longer experience performance problems caused by
this feature. (BZ#732129)

• When attempting to add files to a GFS file system and the file system became

full, the GFS kernel daemon did not properly release resources allocated for
inodes that could not be created. This could result in file system corruption.
This patch introduces new cleanup code, which removes partially created inodes
and releases allocated resources correctly. (BZ#761157)

All users of gfs-kmod are advised to upgrade to these updated packages, which
fix these bugs.
