<ul><li><strong>Affected Versions</strong> <i>v15.2.5</i> added</li></ul><p>Seems to:</p>
<p>(1) happen in libvirt VMs running on slower hardware (e.g. nested virt)<br />(2) be a recent regression</p>

<ul></ul><p>Note: this problem is known to arise (only on machines with root filesystem on HDD) the first time "ceph orch apply" is run after "cephadm bootstrap" completes.</p>
<p>I found it's enough to wait one minute, after "ceph bootstrap" command completes, and before issuing the "ceph orch apply" command to create OSDs, to make the problem go away.</p>
<p>Could it be that this is just a consequence of cephadm being asynchronous? Is it possible that running "ceph orch apply" immediately after "cephadm bootstrap" returns catches mgr/cephadm unprepared - maybe it is still working through its startup routine, for example?</p>

<ul></ul><p>The moral of the story is: wait for the bootstrap <abbr title="s">MON</abbr> and <abbr title="s">MGR</abbr> to appear in "cephadm ls" before proceeding with "ceph orch apply".</p>
