Performing the Upgrade

This section describes how to perform the gray upgrade.

Procedure

1. Log in to a node as user root.

2. Create a directory for the new package.

   mkdir -p /opt/software/gaussdb_upgrade
   

3. Upload the new package to the /opt/software/gaussdb_upgrade directory and decompress it.

4. Go to the script directory generated after the installation package is decompressed.

   cd /opt/software/gaussdb_upgrade/script
   

5. Execute the gs_preinstall script before gray upgrade.

   ./gs_preinstall -U omm -G dbgrp  -X /opt/software/GaussDB_Kernel/clusterconfig.xml
   

6. Switch to user omm.

   su - omm
   

7. If the database is normal, run the following command to perform the gray upgrade:

   Example 1: Execute the gs_upgradectl script to perform a gray upgrade.

   gs_upgradectl -t auto-upgrade -X /opt/software/GaussDB_Kernel/clusterconfig.xml --grey
   

8. If the database is normal, run the following command to perform specified nodes upgrade:

   Example 1: Use the gs_upgradectl script to perform a specified node upgrade.

   gs_upgradectl -t auto-upgrade -X /opt/software/GaussDB_Kernel/clusterconfig.xml --grey -h hostname0
   

   Example 2: Use the gs_upgradectl script to perform multiple specified nodes upgrade.

   gs_upgradectl -t auto-upgrade -X /opt/software/GaussDB_Kernel/clusterconfig.xml --grey -h hostname0,hostname1
   

9. If the database is normal, run the following command to perform the remaining nodes upgrade:

   gs_upgradectl -t auto-upgrade -X /opt/software/GaussDB_Kernel/clusterconfig.xml --grey --continue
