Description

ros2 bag reindex does not recreate message index in bags whose recording was terminated forcefully.

Expected Behavior

When reindex successfully finishes, I'd expect the bag to be 100% usable, same as bags recorded fully.

Actual Behavior

$ ros2 bag reindex rosbag2_2025_05_08-14_09_36

To Reproduce

  1. Play a well working bag
  2. ros2 bag record -a in another console
  3. kill -9 the recording node
  4. ros2 bag reindex $bag
  5. ros2 run rqt_bag rqt_bag $bag

System (please complete the following information)

  • OS: Ubuntu Noble
  • ROS 2 Distro: Jazzy
  • Install Method: APT
  • Version: release

Additional context

Bag recording can be forcefully terminated for various reasons, e.g. voltage spikes on power distribution which reboot the PC, batteries running out etc.

@peci1 Can you please try to use mcap recover bag_file from the https://mcap.dev/guides/cli before running ros2 bag reindex $bag command?
