Note that you will need as much free space as your database uses at the moment, plus a couple of GB. You can check the MongoDB documentation for more details:</p> <p><a href="https://docs.mongodb.com/v2.6/faq/storage/#how-do-i-reclaim-disk-space">https://docs.mongodb.com/v2.6/faq/storage/#how-do-i-reclaim-disk-space</a></p> <p>This can help improve content view promotion time among other tasks. </p> <p>The process would be:</p> <ul> <li>Stop Satellite services with <code>katello-service stop</code> .</li> <li>Backup your MongoDB ; a tar would suffice or use <code>katello-backup</code> .</li> <li>Launch the repair: <code>mongod --dbpath {{ mongodb_path }} --repair</code></li> <li>Start services with <code>katello-service start</code> . </li> </ul> <p>This can reduce MongoDB database size up to 50% and halve publication time :-)</p> <p>Happy hacking!</p>mongodbsatellite6tipshttps://www.frangarcia.me/posts/satellite-62-pruning-mongodb-database/Sat, 29 Jul 2017 16:22:20 GMT
