RHBA-2008:0501 - Bug Fix Advisory

Topic

Updated gfs2-kmod packages that fix a bug are now available for Red Hat
Enterprise Linux 5.2 (kernel release 2.6.18-92.el5).

Description

The gfs2-kmod packages contain modules that provide the ability to mount
and use GFS2 file systems.

These updated packages fix the following bug:

• during heavy I/O, GFS2 could get stuck in the readv() function, waiting

for a pagelock. This would cause the filesystem to hang.

NOTE: While single-node stability has been improved with this update, GFS2
remains a Technology Preview feature.

Users are advised to upgrade to these latest gfs2-kmod packages, which
resolve this issue and are updated for use with the 2.6.18-92.el5 kernel
included in Red Hat Enterprise Linux 5.2.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
