GitLab Backup to Ceph Object Gateway
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.

Ceph Nautilus and NFS-Ganesha

this is my braindump on setting up NFS-Ganesha to serve 3 separate directories on my CephFS using 3 separate cephx users.
GitLab Backup to CephFS
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
Hardware changes to my Ceph Nautilus Cluster
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.
Four TerraMaster F5-422 with Ceph
After installing RHEL 8, I started building a Ceph Nautilus cluster with my four TerraMaster F5-422 nodes.

TerraMaster F5-422 with RHEL8
In further happy distro hopping (since Ansible makes this quite painless), I installed RHEL8 on my four TerraMaster F5-422.
UniFi Switch 16 XG fan modification
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.
Install four TerraMaster F5-422 with CentOS Stream
I received my 3 additional TerraMaster F5-422.
Time to install CentOS Stream in preparation for Ceph Luminous.
Ansible 2.8 venv on Fedora 31 for ceph-ansible stable-4.0
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.
UniFi Switch 16 XG initial bringup
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.
