Ceph - Test object replication across hosts
|
|
===========================================
|
|
|
|
This document captures steps to validate object replcation is happening across
|
|
hosts or not .
|
|
|
|
|
|
Setup:
|
|
======
|
|
- Follow OSH single node or multinode guide to bring up OSH envronment.
|
|
|
|
|
|
|
|
Step 1: Setup the OSH environment and check ceph cluster health
|
|
=================================================================
|
|
|
|
.. note::
|
|
Make sure we have healthy ceph cluster running
|
|
|
|
``Ceph status:``
|
|
|
|
.. code-block:: console
|
|
|
|
ubuntu@mnode1:/opt/openstack-helm$ kubectl exec -n ceph ceph-mon-5qn68 -- ceph -s
|
|
cluster:
|
|
id: 54d9af7e-da6d-4980-9075-96bb145db65c
|
|
health: HEALTH_OK
|
|
|
|
services:
|
|
mon: 3 daemons, quorum mnode1,mnode2,mnode3
|
|
mgr: mnode2(active), standbys: mnode3
|
|
mds: cephfs-1/1/1 up {0=mds-ceph-mds-6f66956547-c25cx=up:active}, 1 up:standby
|
|
osd: 3 osds: 3 up, 3 in
|
|
rgw: 2 daemons active
|
|
|
|
data:
|
|
pools: 19 pools, 101 pgs
|
|
objects: 354 objects, 260 MB
|
|
usage: 77807 MB used, 70106 MB / 144 GB avail
|
|
pgs: 101 active+clean
|
|
|
|
io:
|
|
client: 48769 B/s wr, 0 op/s rd, 12 op/s wr
|
|
|
|
|
|
- Ceph cluster is in HEALTH_OK state with 3 MONs and 3 OSDs.
|
|
|
|
|
|
Step 2: Run validation script
|
|
=============================
|
|
|
|
.. note::
|
|
Exec into ceph mon pod and execute the validation script by giving pool name as
|
|
first argument, as shown below rbd is the pool name .
|
|
|
|
.. code-block:: console
|
|
|
|
ubuntu@mnode1:/opt/openstack-helm$ /tmp/checkObjectReplication.py rbd
|
|
Test object got replicated on these osds: [1, 0, 2]
|
|
Test object got replicated on these hosts: [u'mnode1', u'mnode2', u'mnode3']
|
|
Hosts hosting multiple copies of a placement groups are:[]
|
|
|
|
- If there are any objects replicated on same host then we will see them in the last
|
|
line of the script output
|
