debian deb packages update are not restarting services. (So, I think it should be the same for ubuntu).
you need to restart daemons in this order: -monitor -osd -mds -rados gateway http://ceph.com/docs/master/install/upgrading-ceph/ ----- Mail original ----- De: "Stephen Jahl" <stephenj...@gmail.com> À: "Gregory Farnum" <g...@gregs42.com> Cc: "Daniel Schneller" <daniel.schnel...@centerdevice.com>, "ceph-users" <ceph-users@lists.ceph.com> Envoyé: Mardi 3 Février 2015 17:55:18 Objet: Re: [ceph-users] Update 0.80.7 to 0.80.8 -- Restart Order I just went through and updated my Ubuntu 14.04 80.7 cluster to 80.8 this morning. The package updates looked like they triggered _starts_ for some services (ceph-all, ceph-msd-all), but not restarts. ceph-mon and ceph-osd services were _not_ restarted, allowing me to restart them in the order I desired. -Steve On Mon, Feb 2, 2015 at 11:28 AM, Gregory Farnum < g...@gregs42.com > wrote: Oh, yeah, that'll hurt on a small cluster more than a large one.

I wouldn't worry about it. :) That is good to know. One follow-up then: If the packets trigger restarts, they will most probably do so for *all* daemons virtually at once, right? So that means that all OSDs on that host will go down at the same time. That sounds like a not so good idea, taking 25% of the cluster down at the same time (provided I go host by host)?
