I should uninstall ceph from my cluster, what is the best solution? I don't want to reinstall everything from scratch

To remove manually all Ceph services throughout the cluster. Be aware all data on Ceph will be lost.

pveceph mds destroy <mdsid>
pveceph osd destroy <osdid>
pveceph mgr destroy <mgrid>
pveceph mon destroy <monid>
rm /etc/ceph/ceph.conf #removes the link

Run the above commands (depending on service) on every node in the cluster that hosts Ceph services. The corresponding directories should then be gone as well.

systemctl stop ceph-mon@<monid>.service
systemctl disable ceph-mon@<monid>.service
rm /etc/pve/ceph.conf
rm -r /var/lib/ceph/mon/ceph-<monid>/

ATM, this needs to be...

ok, thanks, but you say it's better to reinstall the cluster or will these commands clean my system anyway?

cluster itself has nothing to with ceph.
so you can remove ceph,
but be careful doing that,
because data stored on Ceph will be wiped.
if your guests are stored on Ceph, their storage will be wiped.

I moved all the hosts to local

I moved all the hosts to local

Should be written :
"I moved all the guests to local"
