When I built my Ceph cluster in March 2020, I used old SATA HDDs I still had on the shelf. It was always clear that at some point these old consumables would die and need replacing. That time has come and I went with 3x 2TB SATA SSD OSD per node.
Just a short write-up on the state of my TerraMaster F5-433 Ceph cluster now that it has been in use for about 3 years.
This is a quick braindump of setting up our home GitLab instance (on CentOS 8) to backup to an existing Ceph Object Gateway using the S3 API.

This is a quick braindump of setting up our home GitLab instance (on CentOS 8) to backup
to an existing CephFS but with access limited to the directory /GitLab_backup.
[root@gitlab ~]# df -h /mnt/cephfs-GitLab_backup/

I made some hardware changes to my Ceph Nautilus cluster.
While previously I used one SSD shared between the operating system and Ceph, I did want a clean setup where the OS and Ceph are on separate devices.
After installing RHEL 8, I started building a Ceph Nautilus cluster with my four TerraMaster F5-422 nodes.
In further happy distro hopping (since Ansible makes this quite painless), I installed RHEL8 on my four TerraMaster F5-422.
I received my 3 additional TerraMaster F5-422.
Time to install CentOS Stream in preparation for Ceph Luminous.
I installed Fedora 29 on my TerraMaster F5-422 for a quick Ceph test.
Obviously if you plan to use Fedora on this hardware for anything more than a quick test, use the latest version! Or try RHEL7 or CentOS Stream on it.
This is my braindump.
I reinstalled my TerraMaster F5-422 with CentOS Stream.
