[DRAFT] Upgrading to the Latest SCS Version for Rocky Linux 8

Important

This document is intended to provide upgrading steps for the latest SCS version for Rocky Linux 8 and above. If you are planning to migrate from CentOS 7 to Rocky Linux 8, please refer to the doc here.

Upgrade Notes

Complete the SCS upgrade first if upgrading both SCS and Swarm Storage simultaneously. Then add the new Swarm Storage component to the SCS repo (using scsctl repo component add ...).

Refer to the following steps to upgrade SCS:

Disable the SELinux.
1. Check if SELinux is enabled or disabled. In a default RL8 installation, it will be Enforcing. However, if it is already disabled, skip to step 2.
```
getenforce
```
2. Disable SELinux, by editing the /etc/selinux/config file, commenting out the line SELINUX=enforcing or SELINUX=permissive, and adding the line SELINUX=disabled. Then reboot the server after saving the file.
```
vi /etc/selinux/config
...
#SELINUX=enforcing
SELINUX=disabled
...
reboot
```
Install the new RPM.

rpm -Uvh swarm-scs-[version].x86_64.rpm

Run the following command.

scsctl diagnostics upgrade_check

Note

Refer to the following step if an error occurs during the upgrade_check command:

systemctl restart swarm-platform && sleep 90

Run the diagnostics check.

scsctl diagnostics config scan_missing

It shows the below output:
