Hi!
Right now, after adding OSD:

Maybe the developers will pay attention to the letter and say something?

Hi!
I saw the same several times when I added a new osd to the cluster. One-two pg
in "backfill_toofull" state.
In all versions of mimic.

Hello, ceph users,
I see the following HEALTH_ERR during cluster rebalance:
Degraded data redundancy (low space): 8 pgs backfill_toofull
Detailed description:
I have upgraded my cluster to mimic and added 16 new bluestore OSDs
on 4 hosts. The hosts are in a separate region in my crush map, and crush
rules prevented data to be moved on the new OSDs. Now I want to move
all data to the new OSDs (and possibly decomission the old filestore OSDs).
I have created the following rule:
# ceph osd crush rule create-replicated on-newhosts newhostsroot host
after this, I am slowly moving the pools one-by-one to this new rule:
# ceph osd pool set test-hdd-pool crush_rule on-newhosts
When I do this, I get the above error. This is misleading, because
ceph osd df does not suggest the OSDs are getting full (the most full
OSD is about 41 % full). After rebalancing is done, the HEALTH_ERR
disappears. Why am I getting this error?
# ceph -s
