Re: [ceph-users] property upgrade Ceph from 10.2.3 to 10.2.5 without downtime

[Luis Periquito]

I've run through many upgrades without anyone noticing, including in
very busy openstack environments.

As a rule of thumb you should upgrade MONs, OSDs, MDSs and RadosGWs in
that order, however you should always read the upgrade instructions on
the release notes page
(http://docs.ceph.com/docs/master/release-notes/).

Again as a rule of thumb minor version upgrades have little to no
notices regarding upgrade, usually the issue is regarding major
versions.

Hi,

i did exactly the same, with

Centos 7, 2x OSD server ~ 30 OSDs all in all, 3x mon server, 3x mds server

Following sequence:

- Update OSD server A & restart ceph.target service
- Update OSD server B & restart ceph.target service
- Update inactive mon / mds server C & restart ceph.target service
- Update inactive mon / mds server B & restart ceph.target service
- Update active mon / mds server A & restart ceph.target service

Result: No downtime, no issues.
