FreeBSD Kernel Update


Related Docs:   Preparing Servers for H-Sphere Installation

H-Sphere requires that FreeBSD kernel be compiled with quota enabled. To update kernel on a FreeBSD server in an H-Sphere cluster:

  1. Download and install FreeBSD kernel sources.

  2. Under root, change directory to /usr/src/sys/i386/conf, where the kernel source is located:

    # cd /usr/src/sys/i386/conf
  3. In this directory, you will have the default GENERIC kernel configuration file, and, if the custom kernel compilation has been performed, a custom kernel configuration file, for example MYKERNEL.

  4. Open your current kernel configuration file (for example MYKERNEL) and add the line:

    options QUOTA
    Important: We don't recommend modifying the default GENERIC file. Instead, copy its content to a custom file (like MYKERNEL) and perform modifications there!
  5. Compile and install the kernel:

    # /usr/sbin/config MYKERNEL
    # cd ../../compile/MYKERNEL
    # make depend
    # make
    # make install
  6. Reboot FreeBSD server to activate the new kernel settings.

For more information, see generic instructions on Building and Installing a Custom Kernel.
