UFM Enterprise Installation

NVIDIA Unified Fabric Manager (UFM) is a powerful platform for managing InfiniBand scale-out computing environments.
UFM enables data center operators to efficiently monitor and operate the entire fabric, boost application performance and maximize fabric resource utilization.​

Pre-deployments requirements

• Install pacemaker, pcs, and drbd-utils on both servers

  For Ubuntu:

  Copy

  Copied!

              
  
              
  apt install pcs pacemaker drbd-utils
          

  For CentOS/Red Hat:

  Copy

  Copied!

              
  
              
  yum install pcs pacemaker drbd84-utils kmod-drbd84
          

  OR

  Copy

  Copied!

              
  
              
  yum install pcs pacemaker drbd90-utils kmod-drbd90
          

• A partition for DRBD on each server (with the same name on both servers) such as /dev/sdd1. Recommended partition size is 10-20 GB, otherwise DRBD sync will take a long time to complete.

• CLI command hostname -i must return the IP address of the management interface used for pacemaker sync correctly (update /etc/hosts/ file with machine IP)

• Create the directory on each server under /opt/ufm/files/ with read/write permissions on each server. This directory will be used by UFM to mount UFM files, and it will be synced by DRBD.

Installing UFM Containers

On the main server, install UFM Enterprise container with the command below:

            

            
docker run -it --name=ufm_installer --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /etc/systemd/system/:/etc/systemd_files/ \
-v /opt/ufm/files/:/installation/ufm_files/ \
-v /tmp/license_file/:/installation/ufm_licenses/ \
mellanox/ufm-enterprise:latest \
--install
        

On the standby (secondary) server, install the UFM Enterprise container like the following example with the command below:

            

            
docker run -it --name=ufm_installer --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /etc/systemd/system/:/etc/systemd_files/ \
-v /opt/ufm/files/:/installation/ufm_files/ \
mellanox/ufm-enterprise:latest \
--install
        

Downloading UFM HA Package

Download the UFM-HA package on both servers using the following command:

            

            
wget https://www.mellanox.com/downloads/UFM/ufm_ha_5.5.0-9.tgz
        

For Sha256:

            

            
wget https://download.nvidia.com/ufm/ufm_ha/ufm_ha_5.5.0-9.sha256
        

Installing UFM HA Package

For more information on the UFM-HA package and all installation and configuration options, please refer to UFM High Availability User Guide.

1. [On Both Servers] Extract the downloaded UFM-HA package under /tmp/

2. [On Both Servers] Go to the extracted directory /tmp/ufm_ha_XXX and run the installation script. For example, if your DRBD partition is /dev/sda5 run the following command:

   Copy

   Copied!

               
   
               
   ./install.sh -l /opt/ufm/files/ -d /dev/sda5 -p enterprise
           

Configuring UFM HA

There are the three methods to configure the HA cluster:

• Configure HA with SSH Trust (Dual Link Configuration) - Requires passwordless SSH connection between the servers.

• Configure HA without SSH Trust (Dual Link Configuration) - Does not require passwordless SSH connection between the servers, but asks you to run configuration commands on both servers.

• Configure HA without SSH Trust (Single Link Configuration) - Can be used in cases where only one link is available among the two UFM HA nodes/servers.

Configure HA with SSH Trust (Dual Link Configuration)

1. On the master server only, configure the HA nodes. To do so, from /tmp, run the configure_ha_nodes.sh command as shown in the below example

   Copy

   Copied!

               
   
               
   configure_ha_nodes.sh \ 
   --cluster-password 12345678 \ 
   --master-primary-ip 10.10.50.1 \ 
   --standby-primary-ip 10.10.50.2 \ 
   --master-secondary-ip 192.168.10.1 \ 
   --standby-secondary-ip 192.168.10.2 \ 
   --no-vip 
           

   Note

   The script configure_ha_nodes.sh is is located under /usr/local/bin/, therefore, by default, you do not need to use the full path to run it.

   Note

   The --cluster-password must be at least 8 characters long.

   Note

   When using back-to-back ports with local IP addresses for HA sync interfaces, ensure that you add your IP addresses and hostnames to the /etc/hosts file. This is needed to allow the HA configuration to resolve hostnames correctly based on the IP addresses you are using.

   Note

   configure_ha_nodes.sh requires SSH connection to the standby server. If SSH trust is not configured, then you are prompted to enter the SSH password of the standby server during configuration runtime

2. Depending on the size of your partition, wait for the configuration process to complete and DRBD sync to finish. To check the DRBD sync status, run:

   Copy

   Copied!

               
   
               
   ufm_ha_cluster status 
           

Configure HA without SSH Trust (Dual Link Configuration)

If you cannot establish an SSH trust between your HA servers, you can use ufm_ha_cluster directly to configure HA. You can see all the options for configuring HA in the Help menu:

            

            
ufm_ha_cluster config -h  
        

To configure HA, follow the below instructions:

1. [On Standby Server] Run the following command to configure Standby Server:

   Copy

   Copied!

               
   
               
   ufm_ha_cluster config -r standby -e <peer ip address> -l <local ip address> -p <cluster_password> 
           

2. [On Master Server] Run the following command to configure Master Server:

   Copy

   Copied!

               
   
               
   ufm_ha_cluster config -r master -e <peer ip address> -l <local ip address> -p <cluster_password> -i <virtual ip address>
           

Configure HA without SSH Trust (Single Link Configuration)

If you cannot establish an SSH trust between your HA servers, you can use ufm_ha_cluster directly to configure HA. To configure HA, follow the below instructions:

1. 1. [On Standby Server] Run the following command to configure Standby Server:

      Copy

      Copied!

                  
      
                  
      ufm_ha_cluster config \
      -r standby \
      -e 10.212.145.5 \
      -l 10.212.145.6 \
      --enable-single-link
              

   2. [On Master Server] Run the following command to configure Master Server:

      Copy

      Copied!

                  
      
                  
      ufm_ha_cluster config -r master \
      -e 10.212.145.6 \
      -l 10.212.145.5 \
      -i 10.212.145.50 \
      --enable-single-link
              

      You must wait until after configuration for DRBD sync to finish, depending on the size of your partition. To check the DRBD sync status, run:

      Copy

      Copied!

                  
      
                  
      ufm_ha_cluster status
