I looked at this system this morning, and the it actually finished what it was
doing. The erasure coded pool still contains all the data and the cache
pool has about a million zero sized objects:

I setup a cephfs file system with a cache tier over an erasure coded tier as an
experiment:
ceph osd erasure-code-profile set raid6 k=4 m=2
ceph osd pool create cephfs-metadata 512 512
ceph osd pool set cephfs-metadata size 3
ceph osd pool create cache-data 2048 2048
