PRIMECLUSTER Installation and Administration Guide 4.6

3.3 PRIMECLUSTER Installation

You can install PRIMECLUSTER using an installation script.

The installation script is also called the CLI Installer.

It is used to install PRIMECLUSTER on a system in which Linux(R) software and related Fujitsu software have been installed. It is also used for installation of the cluster management server.

See

For details on the installation procedures, see the Installation Guide for PRIMECLUSTER.

After PRIMECLUSTER was installed, perform the following settings so that the CF modules and the GDS modules are not incorporated to an initial RAM disk (initramfs) for kdump:

1. Add the following description to the line of KDUMP_COMMANDLINE_APPEND in /etc/sysconfig/kdump by the same line.

   If GDS is not installed:

   rd.driver.blacklist=cf,symsrv

   If GDS is installed:

   rd.driver.blacklist=cf,symsrv,sfdsk,sfdsksys,sfdsklog,sfdsk_lib

   Example

   Before change:

   KDUMP_COMMANDLINE_APPEND="irqpoll ... acpi_no_memhotplug"

   After change (if GDS is not installed):

   KDUMP_COMMANDLINE_APPEND="irqpoll ... acpi_no_memhotplug rd.driver.blacklist=cf,symsrv"

   After change (if GDS is installed):

   KDUMP_COMMANDLINE_APPEND="irqpoll ... acpi_no_memhotplug rd.driver.blacklist=cf,symsrv,sfdsk,sfdsksys,sfdsklog,sfdsk_lib"

2. Restart the system or the service of kdump.

See

For details on kdump, see the Linux documentation.

Note

When using the ntpdate service to adjust the time at OS startup, rapid time adjustment may be performed by the ntpdate service after each PRIMECLUSTER service is started. Therefore, considering the startup order of systemd, set the time adjustment by the ntpdate service to be completed before each PRIMECLUSTER service below is started.

• fjsvwvbs.service

• smawcf.service

• fjsvsdx.service (if using GDS)

The setup procedure is as follows.

You can skip these steps when not using the ntpdate service.

Setup Procedure:

Perform the following procedure on all the nodes.

1. Create the directories.

   # mkdir /etc/systemd/system/fjsvwvbs.service.d
   # chmod 755 /etc/systemd/system/fjsvwvbs.service.d
   # mkdir /etc/systemd/system/smawcf.service.d
   # chmod 755 /etc/systemd/system/smawcf.service.d

   When using GDS, also create the following directory.

   # mkdir /etc/systemd/system/fjsvsdx.service.d
   # chmod 755 /etc/systemd/system/fjsvsdx.service.d

2. Create the configuration files (ntp.conf) in the created directories.

   # touch /etc/systemd/system/fjsvwvbs.service.d/ntp.conf
   # chmod 644 /etc/systemd/system/fjsvwvbs.service.d/ntp.conf
   # touch /etc/systemd/system/smawcf.service.d/ntp.conf
   # chmod 644 /etc/systemd/system/smawcf.service.d/ntp.conf

   When using GDS, also create the following configuration file.

   # touch /etc/systemd/system/fjsvsdx.service.d/ntp.conf
   # chmod 644 /etc/systemd/system/fjsvsdx.service.d/ntp.conf

3. Add the following setting to each configuration file (ntp.conf) created in step 2.

   [Unit]
   After=time-sync.target

4. Reflect the setting of start/stop order of the PRIMECLUSTER services.

   # systemctl daemon-reload

5. Check the setting of start/stop order of the PRIMECLUSTER services. Make sure that time-sync.target is included.

   # systemctl show fjsvwvbs.service | grep "After="
   # systemctl show smawcf.service | grep "After="

   When using GDS, also check the following service.

   # systemctl show fjsvsdx.service | grep "After="

   If the time-sync.target is not included, make sure that settings step 1 to 4 are correctly done.
