Hi Torkil, We noticed that any backfilling pgs are super slow on erasure coded pools that run on HDDs. Is there any visible progress on the movement itself without pgremapper reductions? You can try using https://github.com/TheJJ/ceph-balancer with ’showremapped’ to get a full status of what’s going on with the backfills.
