Supponiamo che il nodo da reinstallare sia ceph-mon-03
Spengo i servizi mon e mgr:
[root@ceph-mon-03 ~]# systemctl stop ceph-mgr.target [root@ceph-mon-03 ~]# systemctl stop ceph-mon.target [root@ceph-mon-03 ~]# systemctl stop ceph-mon@ceph-mon-03
Elimino il mon:
[root@ceph-mon-03 ~]# ceph mon remove ceph-mon-03
In foreman metto il server nell'HostGroup hosts_all e reinstallo la macchina con AlmaLinux9
Configurazione rete dati:

Cancello l'utente ceph-mon-03:
[root@ceph-mon-01 ~]# ceph auth del mgr.ceph-mon-03 [root@ceph-mon-01 ~]#
Installo ceph:
rpm -e epel-release # e' gia' installato ma disabilitato yum install epel-release rpm -Uvh https://download.ceph.com/rpm-quincy/el9/noarch/ceph-release-1-1.el9.noarch.rpm yum clean all yum update yum install ceph
In foreman metto il server nell'HosGroup ceph_prod
puppet agent -t
Copio da un altro nodo /etc/ceph/ceph.client.admin.keyring
Configuro parte MON:
mkdir /var/lib/ceph/mon/ceph-ceph-mon-03 chown ceph.ceph /var/lib/ceph/mon/ceph-ceph-mon-03 mkdir /tmp/ceph-ceph-mon-03 ceph auth get mon. -o /tmp/ceph-ceph-mon-03/monkeyring ceph mon getmap -o /tmp/ceph-ceph-mon-03/monmap ceph-mon -i ceph-mon-03 --mkfs --monmap /tmp/ceph-ceph-mon-03/monmap --keyring /tmp/ceph-ceph-mon-03/monkeyring touch /var/lib/ceph/mon/ceph-ceph-mon-03/systemd chown ceph.ceph /var/lib/ceph/mon/ceph-ceph-mon-03/* chown ceph.ceph /var/lib/ceph/mon/ceph-ceph-mon-03/store.db/* systemctl start ceph-mon@ceph-mon-03 systemctl enable ceph-mon@ceph-mon-03
