RHBA-2012:0671 - Bug Fix Advisory

Topic

Updated nfs-utils packages that fix one bug are now available for Red Hat
Enterprise Linux 6 Extended Update Support.

Description

The nfs-utils packages provide a daemon for the kernel Network File System (NFS)
server and related tools, which provides better performance than the traditional
Linux NFS server used by most users. These packages also contain the mount.nfs,
umount.nfs, and showmount programs.

This update fixes the following bug:

• Previously, the nfsd daemon was started before the mountd daemon. However,

nfsd uses mountd to validate file handles. Therefore, if an existing NFS client
sent requests to the NFS server when nfsd was started, the client received the
ESTALE error causing client applications to fail. This update changes the
startup order of the daemons: the mountd daemon is now started first so that it
can be correctly used by nfsd, and the client no longer receives the ESTALE
error in this scenario. (BZ#812448)

All users of nfs-utils are advised to upgrade to these updated packages, which
fix this bug.
