Cluster stuck at 15% degraded

[Greg Chavez <greg.chavez@xxxxxxxxx>]

We have an 84-osd cluster with volumes and images pools for OpenStack.  I was having trouble with full osds, so I increased the pg count from the 128 default to 2700.  This balanced out the osds but the cluster is stuck at 15% degraded

That's the output of ceph health detail.  I've never seen a pg with the state active+remapped+wait_backfill+backfill_toofull.  Clearly I should have increased the pg count more gradually, but here I am. I'm frozen, afraid to do anything.  

Any suggestions? Thanks.
