Hello Simon, I think that Khodayar is right. I managed to install a new Ceph cluster on CentOS 8.1. Therefore you will need the ceph-el8.repo for the time being. For some reason, "they" left the py3 packages you mentioned out of EPEL (as with leveldb, but this package appeared luckily last week in EPEL). Please find below the ceph-el8.repo file, which you have to create in /etc/yum.repos.d/ [copr:copr.fedorainfracloud.org:ktdreyer:ceph-el8] name=Copr repo for ceph-el8 owned by ktdreyer baseurl=https://download.copr.fedorainfracloud.org/results/ktdreyer/ceph-el8/epel-8-$basearch/ type=rpm-md skip_if_unavailable=True gpgcheck=1 gpgkey=https://download.copr.fedorainfracloud.org/results/ktdreyer/ceph-el8/pubkey.gpg repo_gpgcheck=0 enabled=1 enabled_metadata=1 This repository - and CentOS 8.x - should have been sufficient to bring up a fresh Ceph cluster. Please let me know if you still have problems in configuring your Ceph cluster. rgds, -gw _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
