Chapter 17. Upgrading Your Cluster from v1.2.2 to v1.2.3

Upgrade the administration server first to support upgrading other daemons in the cluster.

Remove calamari-server, ceph, and ceph-deploy repositories under /etc/yum.repos.d directory from previous installation, download and mount the latest Ceph ISO, run ice_setup, re-initialize Calamari and upgrade Ceph.

Remove the ceph related repositories under /etc/yum.repos.d. For example:

cd /etc/yum.repos.d
sudo rm calamari-server.repo ceph.repo ceph-deploy.repo

To obtain the Red Hat Ceph Storage installation ISO image files for the newer version, visit https://access.redhat.com/articles/1560193.

Execute the following steps:

Download the rhceph-1.2.3-centos-6-x86_64.iso file.

Using sudo, mount the image:

sudo mount -o loop <path_to_iso>/rhceph-1.2.3-centos-6-x86_64.iso /mnt

Using sudo, install the setup script.
```
sudo yum install /mnt/ice_setup-*.rpm
```
Back up your Ceph configuration, log and key files.
Change to your working directory. For example:
```
cd ~/ceph-config
```
Run ice_setup:
```
sudo ice_setup -d /mnt
```
The ice_setup program will install upgraded version of ceph-deploy, calamari server, create new local repositories and a cephdeploy.conf file.
Restart Apache:
```
sudo service httpd restart
```
Restart Calamari:
```
sudo calamari-ctl initialize
```
Upgrade Ceph:
```
ceph-deploy install <admin node>
```
To upgrade the Ceph daemons running on your cluster hosts, see Storage Cluster Upgrade section for details.
