Building ganesha

Building ibm2.7 based rpms

1. Install rpms needed for building ganesha

   • RHEL7.x:

     yum groupinstall 'Development Tools'
     
     yum install cmake krb5-devel bison flex doxygen libuuid-devel \
     libblkid-devel libcap-devel dbus-devel python-devel libattr-devel \
     libnfsidmap-devel libwbclient-devel
     

   • RHEL 8, apart from above, install these as well:

     yum install libnsl2-devel python3-devel selinux-policy-devel \
     libtirpc-devel
     

2. Install gpfs samba packages for AD kerberos support. Make sure you install Spectrum Scale Samba package (gpfs.smb) and its development package (gpfs.smb-devel). This step can be ignored if AD kerberos support is not needed.

3. git clone, checkout ibm2.7 and checkout submodules:

   git clone https://github.com/ganltc/nfs-ganesha.git
   cd nfs-ganesha
   git checkout <ibm2.7 or tag>
   git submodule update --init
   

4. Modify GANESHA_EXTRA_VERSION string in src/CMakeLists.txt file. This makes it clear that these rpms are privately built! For example having something like this:

   set(GANESHA_EXTRA_VERSION -ibm050.xyz)

5. Make a new build directory and run cmake from there:

   mkdir build && cd build && cmake ../src -DBUILD_CONFIG=rpmbuild \
   -DCMAKE_BUILD_TYPE=Release -DUSE_FSAL_GPFS=ON -DUSE_ADMIN_TOOLS=ON \
   -DUSE_GUI_ADMIN_TOOLS=OFF -DUSE_DBUS=ON
   

   Optionally, add "-D_MSPAC_SUPPORT=ON" for AD kerberos support!

6. Verify that cmake really did what you wanted! In particular look at its output and verify that it honored your features FSAL_GPFS, ADMIN_TOOLS, DBUS and MSPAC_SUPPORT etc.

7. Make source tarball for rpmbuild:

   make dist
   

8. Build rpms:

   QA_RPATHS=2 rpmbuild -ta nfs-ganesha*.tar.gz
