My 3-node Ceph cluster (14.2.4) has been running fine for months. However,
my data pool became close to full a couple of weeks ago, so I added 12 new
OSDs, roughly doubling the capacity of the cluster. However, the pool size
has not changed, and the health of the cluster has changed for the worse.

Thanks for the reply. I dialed up the value for max backfills yesterday,
which increased my recovery throughput from about 1mbps to 5ish. After
tweaking osd_recovery_sleep_hdd, I'm seeing 50-60MBPS - which is fairly
epic. No clients are currently using this cluster, so I'm not worried about
tanking
uld be appreciated.

Hi, Ceph brain trust:
I'm still trying to wrap my head around some capacity planning for Ceph,
and I can't find a definitive answer to this question in the docs (at least
one that penetrates my mental haze)...
Does the OSD host count affect the total available pool size? My cluster
consists of th
code shards are separated across hosts and a single host failure
will not affect availability.
I think this means what I thought it would mean - having the OSDs
concentrated onto fewer hosts is limiting the volume size...

Stumbling closer toward a usable production cluster with Ceph, but I have
yet another stupid n00b question I'm hoping you all will tolerate.
I have 38 OSDs up and in across 4 hosts. I (maybe prematurely) removed my
test filesystem as well as the metadata and data pools used by the deleted
filesyst
