Description

Running pulp-2.11.0 I had celery worker crashing. A bugzilla indicated that perhaps updating the ostree rpm would correct this problem. I updated to ostree-2016.15. A sync generated this in /var/log/messages

The worker SEGFAULT caused by a bug in libostree is corrupting the pulp "backing" ostree repository causing:

LibError: GLib.Error('No such file or directory', 'g-io-error-quark', 1)

to be raised during publishing.

Both the RHEL7 atomic channel and Satellite 6 channels have really old versions of ostree. The segfault can be reproduced using ostree 2016.5.3. But, so for, I have not been able to reproduce the segfault with 2017.1. Discussed with Colin Walters (atomic team) and he assessed the risk of satellite providing ostree 2017.1 on EL7 to be low. Given this issue appears to be fixed, I will recommend this.

The next step is to reproduce the broken repository and try to fix in ways less drastic than deleting the corrupted repository. I'm hoping that running something like:

ostree prune

may have a side effect of repairing the broken repository. If so, it would not be a bad idea to have the pulp ostree plugin run this before every sync for 2 reasons:
- The prune removes un-referenced objects which will recover wasted disk space.
- Repair broken repository

The 2nd has not yet been proven.

Stay tuned....

No luck using "ostree prune" . Sent email to atomic group asking for help. The main reason I don't want to delete/re-create the repository is that deleting the repository will create broken links in the published repositories. In any case, we'd need log the path to the "backing" repository.

The approach to resolve this includes both an attempt to prevent the local repository from being corrupted and providing safe tooling to repair the local repository after is has been corrupted.

I have seen the local repository get corrupted when a pull is interrupted by a connection reset by peer. Then, the subsequent publish (pull-local) crashes the celery worker.

- recommend users use libostree 2017.1 or newer.
- use the --repair | -r sync option to fix corrupted repositories. Or, repair=True using the API.

I will continue to pursue this with the atomic team. I can provide them a corrupted repository in hopes they can prevent the corruption in libostree.
