Re: [ceph-users] Mixing CEPH versions on new ceph nodes...
Hi, 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... 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...

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.
