Hi folks, We are in the process of shrinking a CEPH cluster from around 2000 osds to 300 osds. We need to reduce our pg count from 16384 to 8192. After setting pg_num to 8192, it’s currently it’s taking 3 hours to reduce the pool’s PG count by one. Which given the number of PGs, will take over 2 years to complete. Are there any tunables to increase the speed of pg merging? Our alternative is to create a new pool and transfer the data Regards, Justin _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
