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/#recovering-a-monitor-s-broken-monmap
This way the remaining MON will be the only one in the map and will have
quorum and the cluster will work again.
