  • Full reboot notifies every chassis in the cluster to reboot itself at the same time, meaning that the entire cluster will temporarily be offline as the chassis reboot.

    Full reboot

    Code Block
    languagebash
    platform restart storagecluster --full

  • Rolling reboot is a long-running process that keeps the cluster operational by rebooting the cluster one chassis at a time, until the entire cluster has been rebooted. A rolling reboot includes several options, such as to limit the reboot to one or more chassis:

    Rolling reboot

    Code Block
    languagebash
    platform restart storagecluster --rolling 	
	[--chassis <comma-separated system IDs>]
	[--skipConnectionTest]
	[--skipUptimeTest]
	[--continueWithOfflineChassis]
	[--stopOnNodeError]

Requirements

Before a rolling reboot can begin, these conditions must be met:

  1. All chassis targeted for rebooting must be running and reachable. If you have offline chassis, be sure to set a flag to have them ignored:

    • To skip the connection check altogether, add the flag --skipConnectionTest

    • To have the reboot process ignore currently offline chassis, add the flag --continueWithOfflineChassis

  2. All chassis must have an uptime greater than 30 minutes. To skip this requirement, add the flag --skipUptimeTest

Managing Rolling Reboots

You have 10 seconds to cancel a rolling reboot before it begins. Once a rolling reboot has started, it will stop and report an error if any of these occur:

Note

The deploy storage --upgrade command is used for both upgrades and downgrades of Storage versions.

  1. Upload the new version of the Swarm Storage software to Platform server, making sure that the <version-name> matches the version of Swarm Storage being uploaded:

    title
    Code Block
    languagebash
    platform upload storageimages -i <path-to-zip> -v <version-name>

platform upload storageimages -i ./storage-9.6.0-x86_64.zip -v 9.6
    Info

    Note
    : The zip file 
     to use 
     above is contained 
     with 
    within the Swarm-{version}-{date}.zip file
     that was downloaded
    . Inside this zip, 
     there is 
     a folder called Storage 
     which 
     contains a file called storage-{version}-x86_64
    .zip
    .
     This is the 
    zip
     file to use for the command above
    .
  2. Get a full listing of all of the nodes and their IPs, MAC addresses, and system IDs:
     Code Block
    languagebash
    platform list nodes --state Deployed 
  3. Using the list of system IDs, deploy the upgrade on each of the nodes. If you want to restart the node immediately after upgrade, run that command as well:
     Code Block
    languagebash
    platform deploy storage --upgrade -v 9.2.1 -y <system-id>
platform restart storagenode -y <system-id>
  4. If you did not restart each node individually, restart the cluster now, either full or rolling:
     Code Block
    languagebash
    platform restart storagecluster --full
or
platform restart storagecluster --rolling [<options>]
