Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Ahmed Nazmy 2018-02-26 06:35:27 UTC 
Description of problem:

If satellite fails to save a valid docker blob on disk due to any issue (disk full, network glitch), there are not means to force rechecking of a docker repo units similar to what we have for rpm repos.

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

pulp-client-1.0-1
satellite-6.2.13-4.0.el7sat
pulp-server-2.8.7.17-1.el7sat
pulp-docker-plugins-2.0.3.1-1.el7sat
python-crane-2.0.2.1-1.el7sat

How reproducible:
Always

Steps to Reproduce:
1. Setup a small /var/cache/pulp & /var/lib/pulp to hit limits soon
2. Sync some docker repos to fill-up space
3. Error similar to below should be noticed on disk fill-up (Notice its cache that got hit first) :
~~~
Jan 18 10:54:22 satellite.example.com pulp[53455]: nectar.downloaders.threaded:ERROR: (53455-15136) [Errno 28] No space left on device: u'/var/cache/pulp/reserved_resource_worker-6.com/d11a02d8-0a35-40ae-b8f1-301aea436200/sha256:2d36a0f107a4e56b82b2052f02896e58ccabca0d539bfef3f059ebe776c43443'
~~~

4. Verify docker repo sync is marked as complete from WebUI.

5. mentioned docker_blob is has a broken symlink to a missing file on disk:
~~~
# ls -al /var/lib/pulp/published/docker/v2/master/*openshift3_metrics-hawkular*/*/blobs/sha256:2d36a0f107a4e56b82b2052f02896e58ccabca0d539bfef3f059ebe776c43443

lrwxrwxrwx. 1 apache apache   177 Feb 21 11:42 sha256:2d36a0f107a4e56b82b2052f02896e58ccabca0d539bfef3f059ebe776c43443 -> /var/lib/pulp/content/units/docker_blob/06/2fa53cb04a019956f3d7e475a25bd0e8a0b86d21bb1582e50faa2c8f3676dc/sha256:2d36a0f107a4e56b82b2052f02896e58ccabca0d539bfef3f059ebe776c43443
~~~
5. Increase  /var/cache/pulp & /var/lib/pulp disk space to accommodate more docker_blobs

6. Trying to delete/recreate/re-sync this repo doesn't fix the problem.

 
Actual results:

Satellite/pulp wrongfully report docker repo sync is complete, while actually its not, deleting, readding and resyncing the repo from WebUI doesnt actually recover the missing blobs.


Expected results:

Add CLI (hammer/pulp-admin) and WebUI functionality to force content validation for docker repos on syncing.
