How to avoid creation of upgrade.log file in 3.10.0?

[9800]

Hello!

Is it possible to avoid creating the upgrade.log file? We are running on a read-only file system, and i can’t figure out how to disable the creation of this file after updating from 3.8.21 to 3.10.0 (we are using the same config and deployment, only version has changed). 

With 3.8.21, when running i see: 

log(s) : 

<stdout>

However after upgrading to 3.10.0, i now see:

Logs: /var/log/rabbitmq/rabbit@app_upgrade.log

<stdout> 

Which of course crashes when run on the read-only file system.

I have tried variations of:

log.console = true

log.file = false

log.upgrade.file = false

And also setting RABBITMQ_LOGS=-

Any ideas?

Hello,

Thanks for the report. My guess is that the fix for this issue changed the behavior for the upgrade file - https://github.com/rabbitmq/rabbitmq-server/issues/4303

For now you'll have to use a writable file system for /var/log/rabbitmq. I'll file an issue for us to investigate and fix this.

Thanks,

Luke
