Deploying the Client

The current client is based on openEuler 20.03 and needs to be deployed in an openEuler 22.03 container.

1. Start a container on a client node.

   1 2 3

   podman load -i ceph_release.tar podman tag image_id localhost/ceph_release_x86:v17.2.7 podman run --name client1 --hostname client1 --privileged --net=host --ipc=host -dti localhost/ceph_release_x86:v17.2.7 /usr/sbin/init

2. Synchronize configuration files from the server to the client.

   scp -r ceph1:/etc/ceph/ceph.conf /etc/ceph/
   scp -r ceph1:/etc/ceph/ceph.client.admin.keyring /etc/ceph/
   
   podman cp /etc/ceph/ceph.conf client1:/etc/ceph/
   podman cp /etc/ceph/ceph.client.admin.keyring client1:/etc/ceph/

3. Go to the client container and query the cluster status.

   podman exec -it client1 /bin/bash
   ceph -s

   

   

   By default, Ceph 17 automatically adjusts the number of PGs based on the number of OSDs. You need to disable this configuration.

   ceph osd pool set ${pool_name} pg_autoscale_mode off
