Mixing CEPH versions on new ceph nodes...

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
