Hi all,
We've recently run into an issue where our single ceph rbd pool is throwing errors for nearfull osds. The OSDs themselves vary in PGs/%full with a low of 64/78% and a high of 73/86%. Is there any suggestions on how to get this to balance a little more cleanly? Currently we have 360 drives in a single pool with 8192 PGs. I think we may be able to double the PG num and that will balance things a bit cleaner but I just wanted to see if there may be anything the community suggests other than that. Let me know if there's any further info I forgot to provide if that'll help sort this out.
Thanks,
