RHEA-2017:2779 - Product Enhancement Advisory

Topic

Updated nfs-ganesha packages that fix several bugs and add various enhancements are now available.

Description

NFS-Ganesha is a user space file server for the NFS protocol
with support for NFSv3, v4, v4.1, pNFS.

Red Hat Gluster Storage's support of NFS-Ganesha is based on v2.4.4 of the NFS-Ganesha release.

This rebase includes the following enhancements:

• Rebase package(s) to version:

nfs-ganesha-2.4.4
nfs-ganesha-gluster-2.4.4
nfs-ganesha-debuginfo-2.4.4

This advisory includes several bug fixes that improves stability and usability, including the dynamic update export feature.The most significant bug fixes are:

• With this release, the dependency over firewalld is removed and NFS-Ganesha can be installed with ease without installing firewalld. (BZ#1410709)
• When multiple paths with the same parent volume are exported via NFS-Ganesha, the handles maintained by the server of the files/directories common to those paths would get merged. Due to this, unexporting one of those shares may result in segmentation fault of the server when accessed via another share mount. With this fix, the refcount of such shared objects is maintained and are released only when all the exports accessing them are unexported. There is hence no issues accessing one share while unexporting another one which shares the same parent volume. (BZ#1425753)
• The NFS-Ganesha configuration file is stored in shared storage and if the shared storage is not mounted, then the NFS-Ganesha service will not start. With this fix, system init scripts have been defined and updated to make sure that shared storage is mounted before starting the NFS-Ganesha service and NFS-Ganesha will start post reboot. (BZ#1451981)

Users of NFS-Ganesha with Red Hat Gluster Storage are advised to upgrade to
this updated package.
