CHAPTER 4
Managing Updates
Take note of the following before you start updating nodes:
• To check for and download updates, the cluster must be healthy and each node in the infrastructure
must be able to open outgoing Internet connections. This means, in particular, that cluster DNS must
be configured and point to a DNS able to resolve external host names. For more details, see the
Acronis
Cyber Infrastructure 3.0 Administrator’s Guide
.
• Unassigned nodes cannot be updated.
• Updates are applied to one storage cluster node at a time.
• If a reboot is required:
•
Highly available storage services will continue working.
•
Virtual machines in the compute cluster will be suspended.
•
If the management node HA cluster is configured, the admin panel will remain accessible, although
you may expect a lag when it moves to an online node from the one being rebooted.
• Disable any third-party repositories before updating.
To update the storage cluster from the admin panel, do the following:
1. Open the
SETTINGS
>
Updates
screen and click
CHECK FOR UPDATES
. The script will run
yum update
on
each node. If updates are available for a node, that node’s status will change to
Update available
.
