Avoiding errors when you upgrade multiple nodes

Edit online

How to avoid an unexpected failure when you run the ltfsee_install --upgrade command on multiple nodes.

Whether you have a single-node cluster or a multiple-node cluster, you can use the ltfsee_install --upgrade command with the --all option on one node alone to update all nodes. Using the --all option is recommended.

When the ltfsee_install --upgrade command is used on multiple nodes, without the --all option, you must run it on one node at a time.

If for some reason you need to upgrade the nodes one-by-one, do the following steps:
  1. Download the upgrade package.
  2. Use the eeadm cluster stop command.
  3. Run the ltfsee_install --upgrade command on one node at a time.
  4. Use the eeadm cluster start command.
