"Steps to reproduce

Steps taken:

1.) Sync repo (ose-egress-router) successfully with Tag pattern "v3.11*,latest"

2.) Run skopeo inspect to show state of repo BEFORE the next sync (attachment: 01_skopeo_inspect_ose-egress-router_2020-02-29_10-16_BEFORE_sync.log)

3.) Change Tag pattern to "v3.11*,v3.9*,latest"

4.) Run Sync with mirror_worker set to DEBUG

• During this sync I think two tags had timeouts
• See attachment "02_repomirror_worker_debug.log"
• It also contains several rollback activities

5.) After the Sync was in status failed I ran another skopeo inspect

See attachment 03_skopeo_inspect_ose-egress-router_2020-02-29_12-02_AFTER_sync.log

skopeo inspects there are multiple tags missing after the sync that were present beforehand. My guess still is the rollback has deleted them.
The most prominent tag that is missing after the sync is the "latest" tag."
