RHBA-2007:0577 - Bug Fix Advisory

Topic

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

Description

The gfs-kmod package contains modules that provide the ability to mount and
use GFS file systems.

These updated packages apply the following bug fixes:

• a cluster could hang while running the df and ls commands.
• corruption could occur over NFS when under memory pressure.
• gfs now manages its slab cache more efficiently.
• gfs could fail to release a glock under memory pressure.
• gfs could fail to display directories that exist on the file system.
• the gfs kernel modules are now dependent upon the kernel ABI and do not

need to be rebuilt for every new kernel.

• mkdir now performs faster on larger file systems.
• gfs now properly substitutes '_' for '/' in table names.
• gfs file systems can now be exported properly with NFSv2.
• performance has been improved on gfs file systems with lock_nolock

exported through nfs.

• a bug was fixed which would cause an incorrect size to be reported when

truncating on systems with quotas.

Users are advised to upgrade to these latest gfs-kmod packages, which are
updated for use with Red Hat Enterprise Linux 5.
