Description Pablo Alonso Rodriguez 2022-04-06 15:28:00 UTC

Description of problem:

The startup script for ovnkube-master container starts ovn-nbctl daemon that logs to ovn-nbctl.log file[1]. However, apart from tailing it, nothing is done with that file. Concretely, it is never rotated.

Recently, one 4.8 cluster has hit the situation where this file grew up to ~24GB size. It was necessary to manually remove that file and restart ovnkube-master.

Version-Release number of selected component (if applicable):

4.8. It seems that 4.10 can hit this problem as well[2] but latest master branch has changed so much that I am not sure if it will be possible for this to happen in 4.11.

How reproducible:

Always (but may take very long and requires no ovnkube-master container restart)

Steps to Reproduce:
1. Let /run/ovn/ovn-nbctl.log grow for long enough

Actual results:

File growing without control

Expected results:

Log file to be eventually rotated.
