When generating a log bundle of Aria Automation on the appliance itself, an error can be observed stating: "[ERROR] Will try to collect a smaller log bundle by limitting the collected files: Not engough disk space."
A log bundle may still be generated, however it will be missing most of the relevant files needed for troubleshooting issues.
In a similar context of low disk space, log bundles generated by Aria Lifecycle Manager may also be very small (sometimes around 2MB) and missing the relavant logs.
Usually, for a production environment (3-node cluster), a more reasonable log bundle size will be closer to hundreds of MB, or even several GB in size.

This can be caused by exisitng/old log bundles present in the /home/root directory of an Aria Automation appliance, taking up the space required to generate a complete log bundle.
Delete older log bundles either directly from the Aria Automation appliance, or from Aria Lifecycle Manager, and then generate a new log bundle.
From the appliance:
Open a SSH session to the Aria Automation appliance, and delete old log bundles under the /home/root directory.
Once the old log bundles are deleted, a new log bundle can be generated directly from the Aria Automation appliance with the command: vracli log-bundle.
From Aria LCM:
In the Aria Lifecycle Manager UI, navigate to Lifecycle Operations > Environments > click the elipses menu of the Aria Automation tile > Logs > Delete Logs.
Then, following the same menu path, select Generate Logs.
