Pre-Upgrade Checks
From Junos Space Platform Release 15.1R1 onward, the system checks for the following before you can upgrade the software:
Free disk space—If a node or a cluster fails to meet the minimum disk requirement, an error message is displayed. The minimum available disk space required is 10 GB in the / partition. The error message lists the IP address of the node that fails to meet the requirement. If you receive this error message, you cannot continue the upgrade.
MySQL replication and PostgreSQL replication—If the MySQL replication or PostgreSQL replication processes are turned off on any of the nodes, a warning message is displayed. Junos Space Platform checks the for Mysql, Mysql_Slave_IO, and Mysql_Slave_sql (MySQL) processes and postgres_sender, postgres_receiver, and postgresql (PgSQL) processes to obtain the status of the replication processes. The warning message lists the processes that are down. If you receive only this warning message, you can either continue or stop the upgrade.
If both the preceding checks fail, an error message is displayed that lists all the preceding information. The upgrade process is not initiated.
How an Upgrade Impacts Previously Installed Junos Space Applications
Junos Space Platform provides the running environment for all Junos Space applications. Hence, the operations of the applications are interrupted during the upgrade. Only the applications that are supported on the version of Junos Space Platform to which you are upgrading are enabled. Other applications running on versions of Junos Space Platform prior to the version to which you are upgrading and that are not supported on that version might be disabled. You must upgrade these disabled applications to the respective compatible version.
