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/
Filesystem      Size  Used Avail Use% Mounted on
ceph-fuse       5.3T  175G  5.1T   4% /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.

I intend to run ceph-ansible stable-4.0 on my Fedora 31 Workstation.

Since F31 comes with Ansible 2.9, but ceph-ansible 4.0 requires ansible>=2.8.8,<2.9, I simply used python -m venv ….

This is my braindump.

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.

It’s been about 2½ months since I started adding ODROID-HC2 nodes to my Ceph Luminous cluster.

This is a quick update on how it’s doing so far.

I built a Ceph Luminous cluster containing seven ODROID-HC2 nodes. This cluster also contains some x86 VMs running on my hypervisor.

I use this cluster mainly as a Ceph playground.

For Ceph use I definitely did not want to mess about with serial console on the ODROID-HC2 (there are 7 nodes to install, there could be more). The instructions include getting rid of the need for serial console during first boot.

After installing Fedora 29 on my ODROID-HC2 nodes, I want to get an ansible user onto them so that my usual Ansible playbooks can configure them.
