Redmine Orchestrator - Tasks #46551 (Resolved): cephadm: Add better a better hint how to add a hosthttps://tracker.ceph.com/issues/465512020-07-15T14:14:32ZStephan Müller
<p>Currently:</p>
<pre>
master:~ # ceph orch host add mgr0 192.168.121.230
Error ENOENT: Failed to connect to mgr0 (192.168.121.230).
Check that the host is reachable and accepts connections using the cephadm SSH key
you may want to run:
> ceph cephadm get-ssh-config > ssh_config
> ceph config-key get mgr/cephadm/ssh_identity_key > key
> ssh -F ssh_config -i key root@mgr0
</pre>
<p>What actually needs to be done:<br /><pre>
master:~ # ceph config-key get mgr/cephadm/ssh_identity_pub > key.pub
master:~ # ssh-copy-id -i "key.pub" root@mgr0
</pre></p>
<p>What the message should look like in the end:<br /><pre>
master:~ # ceph orch host add mgr0 192.168.121.230
Error ENOENT: Failed to connect to mgr0 (192.168.121.230).
Check that the host is reachable and accepts connections using the cephadm SSH key
you may want to add the SSH key to the host:
> ceph config-key get mgr/cephadm/ssh_identity_pub > ~/cephadm_ssh_key.pub
> ssh-copy-id -i ~/cephadm_ssh_key.pub root@mgr0
you may want to check that everything works, before rerunning the command:
> ceph cephadm get-ssh-config > ssh_config
> ceph config-key get mgr/cephadm/ssh_identity_key > ~/cephadm_ssh_key
> ssh -F ssh_config -i ~/cephadm_ssh_key root@mgr0
</pre></p> Orchestrator - Support #46547 (Resolved): cephadm: Exception adding host via FQDN if host was alr...https://tracker.ceph.com/issues/465472020-07-15T12:17:02ZStephan Müller
<p>To reproduce you need nodes that have a subdomain (not like in current Vagrantfile). I used sesdev to find this issue.</p>
<pre>

<p>With the time difference of -7h to the backend, I couldn't log in. The log throw the error `AMT: user info changed after token was issued, iat=%s lastUpdate=%s` which can be found in line 150 in `dashboard/services/auth.py`. I removed as a quick fix line 146 in the same document which said that `user.lastUpdate <= token['iat']` has to be true in order to login.</p> Dashboard - Feature #25164 (New): mgr/dashboard: Display basic performance/utilization metrics of...https://tracker.ceph.com/issues/251642018-07-30T14:30:23ZStephan Müller

<p>This issue is a port from this openATTIC <a href="https://tracker.openattic.org/browse/OP-1072" class="external">issue</a>.<br />For all comments and pictures please look at the original issue.</p>
<p>This Wizard should consist of these three steps:</p>
<ol>
<li>Provide a check list of options that this cluster will be used for. e.g. "openstack", "iSCSI", RGW, CephFS. Also, ask for the expected final size of this cluster.</li>
<li>Generate a dialog similar to the ceph PG calculator, which contains a table of all pools that will be created. each pool should be editable and removable.</li>
<li>Apply</li>
</ol>
<p>This wizard will only be useful, if the cluster is newly created.</p>
<p>Original Description for creating a single pool:</p>
<blockquote>
<p>Once the basic/generic functionality for creating a Ceph Pool exists (e.g. the required REST API call), we should consider creating a "Create Pool" Wizard, that guides the user through the required steps.</p>
<p>Some rough notes about this that were gathered during a call with SUSE about this:</p>
<p>First step after installation - creation of a Crush map depending if there is just one set of disks (one size, all rotational) vs. rotating disk plus SSDs (likely two different sizes?)<br />(<strong>Not</strong> for SSDs used as journal devices)</p>
<p>Crush Map creation? All your disks in one rule set, or use two separate groupings? Reason: to constrain what disks a pool can use (e.g. for creating a cache pool)<br />Can I query an OSD for the size of its disk?<br />Propose a grouping based on what is reported.</p>
<p>Create a pool for one of the following purposes</p>
<p>- Replicated or Erasure Coded? => Explain the pros and cons in sidebar<br />- Cache tiering (only if there are separate rule sets)</p>
<p>If Erasure Coded: Propose k/m values e.g. 5/3 4/2 (dropdown showing existing profiles), algorithm</p>
<p>- Suggest conservative Placement Group Number (use pgcalc algorithm?) (Hint that it can't be decreased and depends on the estimated number of Pools, probably propose a conservative number)<br />Maybe a Checkbox? "Do you intend to create additional pools?"</p>
<p>- Block devices (iSCSI), Virtual Machine Images<br />- Generic object storage</p>
<p>Note: (Cache tiering does not work with RBDs)</p>
<p>- (CephFS)</p>

<p>The details of the Ceph pools in the listing are relatively raw displayed. This should be enhanced and the details should be refined optically.</p>

<ul>
<li>Replica size is only valid for replicated pools.</li>
<li>The "type" defines, which column is valid.</li>
<li>The minimum number of replicas is missing. Maybe even as an optional column.</li>
<li>Show the pool quota.</li>
