I reinstalled the OS on a new SSD disk. How can I rebuild my cluster with only one mons.
If there is one MON still operating you can try to extract its monmap and remove all the other MONs from it with the monmaptool: https://docs.ceph.com/en/latest/man/8/monmaptool/ https://docs.ceph.com/en/latest/rados/troubleshooting/troubleshooting-mon/#r... This way the remaining MON will be the only one in the map and will have quorum and the cluster will work again.
