Hi, guys. I use Luminous 12.2.5.
Automatic bucket index resharding has not been activated in the past. Few days ago i activated auto. resharding. After that and now i see: - very high Ceph read I/O (~300 I/O before activating resharding, ~4k now), - very high Ceph read bandwidth (50 MB/s before activating resharding, 250 MB/s now), - very high RGW cache miss (400 count/s before activating resharding, ~3.5k now). For Ceph monitoring i use MGR+Zabbix plugin and zabbix-template from ceph github repo. For RGW monitoring i use RGW perf dump and my script. Why is it happening? When is it ending?
