Updated gfs-kmod packages that fix two bugs are now available for Red Hat Enterprise Linux 5.
The gfs-kmod packages contain kernel modules that provide the ability to mount and use the Global File System (GFS).
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.
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.
All users of gfs-kmod are advised to upgrade to these updated packages, which fix these bugs.
