installation.md

+### Installation
+## ssh keys exchange
+Choose an admin node to use for the installation process.
+Distribute  the ssh key to all the hosts in the cluster.
+
+## Install the deploy script
+Add the ceph repository
+```
+yum install ceph-deploy
+yum install ntp ntpdate ntp-doc
+```
+## Purge cluster
+```
+ceph-deploy purge qn-cnfslhc ds-001 ds-002 ds-303 ds-304 ds-507
+ceph-deploy purgedata qn-cnfslhc ds-001 ds-002 ds-303 ds-304 ds-507
+ceph-deploy forgetkeys
+
+```
+Create first monitor nodes:
+```
+ceph-deploy new qn-cnfslhc
+```
+This will create the following files:
+```
+ceph.conf
+ceph.mon.keyring
+
+```
+Add the public network to the configuration file:
+```
+public_network = 131.154.128.0/22
+```
+and then deploy the initial monitoring node:
+```
+ceph-deploy mon create-initial
+```
+and the admin keys to the nodes of your cluster
+```
+ceph-deploy admin qn-cnfslhc
+```
+Then deploy the manager node
+```
+ceph-deploy -v mgr create qn-cnfslhc
+```
+If you have a dirty installation you may receive errors like:
+```
+[qn-cnfslhc][ERROR ] [errno 1] error connecting to the cluster
+[qn-cnfslhc][ERROR ] exit code from command was: 1
+[ceph_deploy.mgr][ERROR ] could not create mgr
+[ceph_deploy][ERROR ] GenericError: Failed to create 1 MGRs
+```
+This means that you must remove the old keys from `/var/lib/ceph`
+```
+rm -rf /var/lib/ceph/bootstrap-mgr/
+```
+### Enable dashboard
+```
+yum install ceph-mgr-dashboard # for nautilus
+ceph mgr module enable dashboard
+ceph config set mgr mgr/dashboard/$name/server_addr 131.154.130.69
+ceph config set mgr mgr/dashboard/$name/server_port 5000
+ceph dashboard set-login-credentials admin <password>
+```
+### Add a monitor node
+

maintenance.md

+### Check mon status from socket
+```
+sudo ceph --admin-daemon /var/run/ceph/ceph-mon.qn-cnfslhc.asok config help
+sudo ceph --admin-daemon /var/run/ceph/ceph-mon.qn-cnfslhc.asok config show
+sudo ceph --admin-daemon /var/run/ceph/ceph-mon.qn-cnfslhc.asok
+
+```
