Not peace, full object. If we talk about non-EC pools.
* host1 has pieces of data on osd.1 and osd.2
host1 has copy on osd.1 *or* osd.2

Thanks, man. Thanks a lot. Now I'm understood. So, to be sure If I have 3 hosts,
replicating factor is also 3 and I have a crush rule like:
{
"rule_id": 0,
"rule_name": "replicated_rule",
"ruleset": 0,
"type": 1,
"min_size": 1,
"max_size": 10,
"steps": [

Your pools have proper size settings - is 3. But you crush have only 2
buckets for this rule (e.g. is your pods).
For making this rule work you should have minimum of 3 'pod' buckets.
k
# ceph osd pool ls detail
pool 1 'cephfs_data' replicated size 3 min_size 2 crush_rule 0 object_hash
rjenkins pg_num 32 pgp_num 32 last_change 958 lfor 0/909 flags hashpspool
stripe_width 0 application cephfs
pool 2 'cephfs_metadata' replicated size 3 min_size 2 crush_rule 0 object_hash

after assigning this rule to a pool it stucks in the same state:

Hi Konstantin, thanks a lot for your response.
> Your crush is imbalanced:
I do it deliberately. The group2 of my small-but-helpful ceph cluster
also will be a master-nodes for my new small-but-helpful kubernetes
cluster. And I what I want to achieve is: there are 2 groups of nodes,
and even if o
# ceph osd crush tree
ID CLASS WEIGHT TYPE NAME
-1 3.63835 root default
-9 0.90959 pod group1
-5 0.90959 host feather1
1 hdd 0.90959 osd.1
-10 2.72876 pod group2
-7 1.81918 host ds1
2 hdd 0.90959 osd.
Hi, I've got stuck in a problem with crush rule.
I have a small cluster with 3 nodes and 4 osd. I've decided to split
it to 2 failure domains and made 2 buckets and put hosts in that buckets
like in that instruction
