Reposync ends in a warning with no aparent errors

Problem:

Hi all,

thanks for the help in advance. I`ve been experiencing warnings with the daily reposync plan, for some concrete repositories.
I’ve tried to delete and add again the offending repository with no success. There is no apparent error on the UI:

(I will also add the messages log of the moment)

When trying to run an advanced full sync, I get the error “too many open files”. So that is a new issue that I found out due to the first error.

Expected outcome:
Clean of warnings, green sync

Foreman and Proxy versions:
2.3.3

Foreman and Proxy plugin versions:
3.18.21 Katello

Distribution and version:
RHEL 7

Thanks for the help :slight_smile:

Hey @maramorim!

It seems you’re running into this issue: Issue #7735: RPM repo repair fails with "too many open files" on Katello 3.16.1.2 - Pulp which was fixed with pulpcore 3.9. The version landed in katello 4.0.

Hmm dunno if this is of intereste for anyone, but I was able to get the repos syncin’ again, after enabling debug and checking for more specific error, that led me to this RH discussion:

according with Barry Coleman:

> Vi to /etc/foreman/plugins/katello.yaml and under :pulp add :bulk_load_size: 500 it should look like this less your server name
> 
> :pulp: :url: https://my.hostname.com/pulp/api/v2/ :ca_cert_file: /etc/pki/katello/certs/katello-server-ca.crt :bulk_load_size: 500
> 
> reboot then retry sync

It worked for me,

cheers
