<ul></ul><p>This is a critical change for denser hardware and more threads allocated per OSD. Can we get a message into ceph-deploy as well? Perhaps upon the addition of OSDs over a certain number? Open to suggestions.</p> Ceph - Documentation #6142: Ceph needs mor than 32k pidshttps://tracker.ceph.com/issues/6142?journal_id=403042014-08-28T14:25:03ZDavid Moreau Simarddmsimard@iweb.com
<ul></ul><p>FWIW there might be a bug to extract out of this.

<p>Alfredo,</p>
<p>There is a note here suggesting that ceph-deploy notifies a user if the number of OSDs per node exceeds n#. That is, to suggest increasing the max threadcount.</p> Ceph - Documentation #6142: Ceph needs mor than 32k pidshttps://tracker.ceph.com/issues/6142?journal_id=403492014-08-29T08:07:56ZAlfredo Dezaadeza@redhat.com
<ul></ul><p>Adding a warning if deploying more than N OSDs into a single host sounds entirely reasonable to me and easy to add to ceph-deploy.</p>
<p>What would that number be though? Is anything greater than 20 OK?</p> Ceph - Documentation #6142: Ceph needs mor than 32k pidshttps://tracker.ceph.com/issues/6142?journal_id=403502014-08-29T08:15:57ZWarren Wangwarren@wangspeed.com
<ul></ul><p>Greater than 20 is a safe number. Have not yet seen this issue on a host with 24 OSDs.</p> Ceph - Documentation #6142: Ceph needs mor than 32k pidshttps://tracker.ceph.com/issues/6142?journal_id=409192014-09-10T11:40:15ZAlfredo Dezaadeza@redhat.com
