| Symptom | Thumbnails aren't available on landing pages for some items (especially recently uploaded items) |
| Probable root cause | Reindexing hasn't been run since those items were ingested |
| Recommended solution #1 | Check that sidekiq is running. See https://github.com/gwu-libraries/scholarspace-hyrax/wiki/Sidekiq
|
| Recommended solution #2 | Run reindexing |
| Symptom | Attaching any PDFs to item(s) results in an error |
| Possible root cause | One possible root cause is that the ImageMagick policy.xml file has been overwritten by an update, and no longer allows PDF characterization |
| Recommended solution | Modify policy.xml |
| Symptom | Attaching certain (but not any/all) attachments to item(s) results in an error |
| Possible root cause | One possible root cause is that there is a derivatives folder that was created as owned by a user other than scholarspace. If this is the root cause, the application log should show something similar to Errno::EACCES (Permission denied @ dir_s_mkdir - /opt/scholarspace/scholarspace-derivatives/derivatives/2z/10/wr/01) when trying to upload the attachment in question. |
| Recommended solution | Ensure that all subfolders of /opt/scholarspace/scholarspace-derivatives/derivatives are owned by scholarspace:scholarspace. Can resolve using sudo chown -R scholarspace:scholarspace /opt/scholarspace/scholarspace-derivatives/derivatives

Is solr running? If not, can it be successfully started with sudo service solr start on the Fedora/Solr server?
