Description Daniel Alley 2023-07-27 19:49:10 UTC

Description of problem:

Import dispatches a task-per-repository. For large imports, with large repositories, this means that Pulp can't do anything else until the import is finished or nearly so, as all workers are busy importing repositories.


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

6.12

How reproducible: 100%

Comment 1 Robin Chan 2023-07-28 18:05:11 UTC

The Pulp upstream bug status is at closed. Updating the external tracker on this bug.

Comment 4 Gaurav Talreja 2023-09-26 10:27:14 UTC

VERIFIED.

Tested on Satellite 6.14.0 Snap 17.0
Version: python39-pulpcore-3.22.15-1.el8pc.noarch

Steps and observations:
1. Sync'ed repos as per 2*available pulpcore-workers, created and published the CV, and export a content view version
2. Create a new org, upload manifest and run the content import with IMPORT_WORKERS_PERCENT setting.
3. When IMPORT_WORKERS_PERCENT isn't set in /etc/pulp/settings.py so it is default IMPORT_WORKERS_PERCENT=100, then no syncs were working while import was going on, and after import task completed repo sync worked nearly after an hour for small repos sync.
4. When IMPORT_WORKERS_PERCENT=50 is set in /etc/pulp/settings.py, then while import task is going on, which will utilize half of the available workers and syncs also works along with import without waiting for import tasks to finish.

Also we could check for the workers in use for content-import task with commands like "pulp task list --state running" and "pulp worker list --online"

And we've BZ 2233490 created to make this setting configurable with installer, as per discussion happened in its 6.12.z clone BZ.
