Hi Team, I have an OpenStack Ceph cluster where the Cinder volumes pool uses a cache pool named *volumes_cache*. Due to performance issues, I observed that the cache pool has fewer PGs and a high PG-to-object ratio, approximately 10x higher than normal. For instance, one PG contains around 35,000 objects. I am planning to increase the PG number for the cache pool. For the base pool, I was able to increase the PG count without any issues. However, for the cache pool, I encountered a warning indicating that a force argument is required. In my lab environment, I found that changing the cache pool mode to *none* allowed me to modify the PG number. Since this is my production setup, I would like to know if there is a safe and recommended procedure to increase the PG number of a *cache pool* without impacting the environment. Kindly advise on the best approach. Thanks and Regards Vishnu Bhaskar Acceleron Labs Pvt Ltd Bangalore, India
