RHBA-2009:1045 - Bug Fix Advisory
Synopsis
GFS-kernel bug-fix update
Type/Severity
Bug Fix Advisory
Topic
Updated GFS-kernel packages that fix various bugs and module-loading issues
are now available for Red Hat Enterprise Linux 4.8, kernel release
2.6.9-89.EL.
Description
The GFS-kernel packages contain modules that provide the ability to mount
and use GFS file systems.
These updated packages apply the following bug fixes:
- Prefetching on inode/iopen locks in readdir has improved to prevent the
appearance of a gfs hang.
- A bug that caused GFS to hang in the wait_for_completion function was fixed.
- A syscall on a file residing on gfs no longer returns the id of the
diapered device; it now returns the real device id.
- A bug which caused gfs_grow to cause a kernel oops during I/O has been fixed.
- GFS no longer causes an assertion in certain cases when NFS is being used
on top of a GFS filesystem.
Also, these updated GFS-kernel packages are in sync with the latest
kernel (2.6.9-89.EL). The modules in earlier GFS-kernel packages fail to
load because they do not match the running kernel. It is possible to
force-load the modules; however, with this update, force-loading the
modules is not required.
Users are advised to upgrade to these latest GFS-kernel packages, which
are updated for use with the 2.6.9-89.EL kernel.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
