[ceph-users] Re: Where is a simple getting started guide for a very basic cluster?
The system has been running for years and it would take me weeks to reconfigure all of its services properly. I'm proceeding with just the Debian nodes for now; worst case scenario I'll just have to rent a new server to act as a third node. I was really hoping to use the CentOS one since it's already there. Somebody else mentioned DRBD earlier so I've looked into that too, but in that case I ran into problems with the Debian systems instead because apparently only DRBD 9 and up supports more than two nodes, and the only Debian kernel module packages I've found are for DRDB 8. Ironically, CentOS does have a working kmod-drbd90 package available.

> Why are you talking about version 14 now anyhow? One of my nodes is running CentOS 7 and the latest version I found for it is 14, unless there's a way to get 15 working on it that I don't know about?

I tried installing it via curl but my ceph version is 14.2.22 which is not on the archive anymore so the curl command returns a 404 error html file. How do I get cephadm for 14.2? There is no cephadm for Ceph 14 as the orchestrator was first introduced in version 15. Why are you talking about version 14 now anyhow? As long as your nodes fulfill the requirements for cephadm you can install the latest version of Ceph. PS: Please reply to the list.

Looking up the "manual installation" parts might help, if you can't get the container stuff going for $reasons.

Hi, have you read https://docs.ceph.com/en/reef/cephadm/install/ ? Bootstrapping a new cluster should be as easy as # cephadm bootstrap --mon-ip ** if the nodes fulfill the requirements: - Python 3 - Systemd - Podman or Docker for running containers - Time synchronization (such as chrony or NTP) - LVM2 for provisioning storage devices Regards -- Robert Sander Heinlein Consulting GmbH Schwedter Str. 8/9b, 10119 Berlin https://www.heinlein-support.de Tel: 030 / 405051-43 Fax: 030 / 405051-19 Amtsgericht Berlin-Charlottenburg - HRB 220009 B Geschäftsführer: Peer Heinlein - Sitz: Berlin ___ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
