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.

user@workstation tmp $ s3cmd  --access_key=FOO --secret_key=BAR ls s3://gitlab-backup/

this is my braindump on setting up NFS-Ganesha to serve 3 separate directories on my CephFS using 3 separate cephx users.

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.

In further happy distro hopping (since Ansible makes this quite painless), I installed RHEL8 on my four TerraMaster F5-422.

My new 16 port 10G switch was too loud for my taste. So I fit Noctua NF-A4x20 FLX fans instead.

After the modification, the switch looks the same on the outside.

I received my 3 additional TerraMaster F5-422.

Time to install CentOS Stream in preparation for Ceph Luminous.

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.

This blog now runs on CentOS 8

I bough a UniFi Switch 16 XG, Board Revision 13 (UniFi Software reports 13, while in the pic below I see 11, odd).

These are my notes on initial bringup.

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.
