Red Hat is aware of this issue and is tracking it via the following bug:
This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include
support for the GFS2 file system.
A future kernel update in Red Hat Enterprise Linux 5 will address this issue.
