OS patching checklist
This page contains guidelines for upgrading all installed packages on your TrendMiner server to the latest available versions (only applies to single node installations; does not apply to virtual appliance installations or SaaS installations).
To patch your TrendMiner server:
Create a VM snapshot.
Verify that only the required repositories are enabled:
dnf repolist -v. The list of required repositories is listed in the installation guide.If you have satellite repos / mirrored repos, make sure these contain the latest updates before patching.
Run
dnf update --assumeno. This goes through the full dependency resolution and shows you what would be updated (including install size), but doesn't actually do anything.Verify with command
df -hthat there is still enough free disk space on/,/var,/var/lib/containerd)To apply OS patches run command
dnf update.After installing the patches
rebootthe system.Verify that TrendMiner is running stable via the Edge Manager or ConfigHub services screen. All services should be green.
If TrendMiner is degraded or unavailable after patching:
Do not attempt manual fixes or repository changes to TrendMiner components such as running ansible-playbooks.
If a VM snapshot was taken prior to patching, download the appliance logs and consider reverting to the snapshot to restore service.
In parallel, open a ticket with TrendMiner Support and provide:
Time of patching
Reboot time
Extracted logfiles (from before a potential snapshot restore)
Any obvious errors visible in Edge Manager / ConfigHub
