+===== Update from Jewel to Luminous =====
+Accertarsi che tutti i MON e tutti gli OSD siano up. Accertarsi, con "ceph status', chelo stato sia HEALTH_OK.
+Poi da ceph-mon-01:
+<code bash>
+ceph osd set sortbitwise
+</code>
+Poi sempre da ceph-mon-01:
+<code bash>
+ceph osd set noout
+</code>
+==== Update MON ====
+Su ceph-mon-01, poi ceph-mon-02 e infine ceph-mon-03:
+<code bash>
+rpm -e ceph-release
+rpm -Uvh https://download.ceph.com/rpm-luminous/el7/noarch/ceph-release-1-1.el7.noarch.rpm
+yum clean all
+yum update
+shutdown -r now
+</code>
+Terminato l'update dei monitor verificare da un mon le versioni con:
+<code bash>
+ceph versions
+ceph features
+</code>
+Da un mon:
+<code bash>
+ceph mon feature ls
+</code>
+==== Configurazione manager ====
+Da uno dei 3 mon, creare le chiavi per i manager:
+<code bash>
+ceph auth get-or-create mgr.ceph-mon-01 mon 'allow profile mgr' osd 'allow *' mds 'allow *'
+ceph auth get-or-create mgr.ceph-mon-02 mon 'allow profile mgr' osd 'allow *' mds 'allow *'
+ceph auth get-or-create mgr.ceph-mon-02 mon 'allow profile mgr' osd 'allow *' mds 'allow *'
+</code>
+Su ceph-mon-01:
+<code bash>
+mkdir /var/lib/ceph/mgr/ceph-ceph-mon-01
+chown ceph.ceph /var/lib/ceph/mgr/ceph-ceph-mon-01
+</code>
+Creare il file /var/lib/ceph/mgr/ceph-ceph-mon-01/keyring
+che deve avere questo ownership/mode:
+<code>
+-rw------- 1 ceph ceph
+</code>
+e un contenuto di questo tipo:
+<code bash>
+# cat /var/lib/ceph/mgr/ceph-ceph-mon-01/keyring
+[mgr.ceph-mon-01]
+	key = AQBkuC5aQMCyHhAASi2BbZghbzG7f6vcHXPS8Q==
+</code>
+con il valore della chiave che deve matchare quanto ritornato da "ceph auth get":
+<code bash>
+# ceph auth get mgr.ceph-mon-01
+exported keyring for mgr.c-mon-1
+[mgr.c-mon-1]
+	key = AQBkuC5aQMCyHhAASi2BbZghbzG7f6vcHXPS8Q==
+	caps mds = "allow *"
+	caps mon = "allow profile mgr"
+	caps osd = "allow *"
+</code>
+Abiltare e far partire mgr:
+<code bash>
+systemctl restart ceph-mgr@ceph-mon-01.service
+systemctl enable ceph-mgr@ceph-mon-01.service
+</code>
+Verificare con "ceph status" che il monitor sia attivo
+Fare le stesse operazioni sugli altri 2 monitor node.
+==== Update OSD ====
+Su ceph-osd-01, poi ceph-osd-02 e infine ceph-osd-03:
+<code bash>
+rpm -e ceph-release
+rpm -Uvh https://download.ceph.com/rpm-luminous/el7/noarch/ceph-release-1-1.el7.noarch.rpm
+yum clean all
+yum update
+shutdown -r now
+</code>
+Terminato l'update degli OSD verificare da un mon le versioni con:
+<code bash>
+ceph versions
+ceph features
+ceph osd versions
+</code>
+==== Operazioni da fare prima di updatare i client ====
+Da un minitor:
+<code bash>
+ceph osd require-osd-release luminous
+ceph osd unset noout
+</code>
+In caso di warning (con ceph health) del tipo "HEALTH_WARN application not enabled on 3 pool(s)" taggare i pool in questione, e.g.:
+<code bash>
+ceph osd pool application enable pool1 test-pool
+</code>
+==== Attivazione della dashboard ====
+Da un monitor:
+<code bash>
+ceph mgr module ls
+ceph mgr module enable dashboard
+</code>
+Verificare che la dashboard sia stata abilitata e trovare la relativa URL:
+<code bash>
+ceph mgr module ls
+ceph mgr services
+</code>
+==== Update dei client ====
+Su ogni client:
+<code bash>
+rpm -e ceph-release
+rpm -Uvh https://download.ceph.com/rpm-luminous/el7/noarch/ceph-release-1-1.el7.noarch.rpm
+yum clean all
+yum update
+shutdown -r now
+</code>
+Terminato l'update, verificare da un mon le versioni con:
+<code bash>
+ceph features
+</code>
