Where is a simple getting started guide for a very basic cluster?
I'm pulling my hair trying to get a simple cluster going. I first tried Gluster but I have an old system that can't handle the latest version, so I resorted to Ceph. However, I can't get my cluster to work. I tried to find tutorials but everything uses tools on top of Ceph, whereas I'm trying to use it barebones. (I don't trust nfs or samba for this purpose) The three systems I'm trying to cluster together have a variety of Linux distros, and one of them is discontinued, so I can't use a lot of newer stuff. I need to make do with the commands `ceph`, `ceph-mon`, and `ceph-volume`. I do *not* have access to `ceph-disk` which I ran into a lot online. ChatGPT guided me up to a certain point before she started making stuff up, so I need to start from scratch. I just need to share a directory (or rather a block device in the case of Ceph) across these three systems that already have a secure connection to one another. Can somebody please help me out? Thanks in advance
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 *<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
Looking up the "manual installation" parts might help, if you can't get the container stuff going for $reasons. Den mån 27 nov. 2023 kl 00:45 skrev Leo28C <leo28c@gmail.com>:
