<p>I am trying to install ceph and configure on a mounted disk. I have the disk location, however, I face a problem when I use the --data parameter. </p>

<p><strong>command:</strong> 
ceph-deploy osd create --data /home/ceph-admin/ceph-data/vda node-ip-address</p>

<p><strong>error:</strong> 
ceph-deploy: error: unrecognized arguments: --data</p>

<p><strong>ceph version:</strong>
ceph version 14.2.8 (2d095e947a02261ce61424021bb43bd3022d35cb) nautilus (stable)</p>

<p><strong>ceph-deploy version:</strong> 
1.5.38</p>

<p>All the documentations I found uses the --data parameter. is there any workaround? </p>

<p>please help!</p>

<p>Thanks in advance..</p>

<p>You have to upgrade your <strong>ceph-deploy</strong> to version <strong>2.x</strong> to be able to deploy nautilus to your cluster. The sample commands to update ceph-deploy on ubuntu.</p>

<pre><code>$ wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -
$ echo deb https://download.ceph.com/debian-nautilus/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
$ sudo apt update
$ sudo apt install ceph-deploy
</code></pre>

<p>Hope it can help.</p>
