debian packages don't restart ceph services on package update, maybe it's a bug in rpm packaging ? ----- Mail original ----- De: "Andrija Panic" <andrija.pa...@gmail.com> À: "Wido den Hollander" <w...@42on.com> Cc: ceph-users@lists.ceph.com Envoyé: Dimanche 13 Juillet 2014 23:42:55 Objet: Re: [ceph-users] Mixing CEPH versions on new ceph nodes... Hi Wido, you said previously: Upgrade the packages, but don't restart the daemons yet, then: 1. Restart the mon leader 2. Restart the two other mons 3. Restart all the OSDs one by one But in reality (yum update or by using ceph-deploy install nodename....) - the package manager does restart ALL ceph services on that node by its own... So, I have upgraded - MON leader and 2 OSD on this 1st upgraded host were restarted, folowed by doing the same with other 2 servers (1 MON peon and 2 OSD per host). Is this perhaps a package (RPM) bug - restarting daemons automatically ? Since it makes sense to have all MONs updated first, and than OSD (and perhaps after that MDS if using it...) Upgraded to 0.80.3 release btw. Thanks for your help again. Andrija On 3 July 2014 15:21, Andrija Panic < andrija.pa...@gmail.com > wrote: Thanks again a lot.

Perhaps not smart question, but need to make sure I don't screw something... No, no need to. The librados API didn't change in case you are using RBD storage pool support. Otherwise it just talks to Qemu and that talks to librbd/librados.

No, but the recommendation is not to have this running for a very long period. Try to upgrade all nodes to the same version within a reasonable amount of time. I intend to upgrade CEPH on exsiting 3 nodes anyway ? Recommended steps ? Always upgrade the monitors first! Then to the OSDs one by one.
