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
