I installed Proxmox VE 8.1 on my QNAP TS-473A.
These are my installation notes.
ld;dr: it installs fine but the hardware is not at the quality level I expected, machine was put into electronics recycling in late 2024.
I upgraded my existing ProxmoxVE version 7 install to version 8.1.
As expected, this was hassle free.
These are mainly my notes on cleaning out previous CephFS fiddlings.
These are my configuration notes on using a PiKVM V4 Mini to connect to my four Ceph nodes via a cheap 4-port KVM switch.
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 my braindump on installing cephadm on CentOS Stream 9.
While I use a QNAP TS-473A for my tests plus 2 VMs, the below applies to any machine or VM running CentOS Stream 9 FWIW: My installation and initial configuration is described in the post QNAP TS-473A with CentOS Stream 9.
I want a playground for Ceph’s cephadm that was introduced with Octopus and is also present in Pacific.
So I cleanly took my QNAP TS-473A out of my existing Ceph Nautilus cluster again
(because I have enough combined capacity on my F5-422 nodes to be able to remove the OSDs in the TS-473A)
and installed Fedora Server 35 plus cephadm from upstream.
While for my virtualisation needs I am firmly in the Red Hat camp, an article in ix 9/2021 piqued my interest.
Since I was on a week of ‘staycation’ and the T7910 was not in use, I decided to test Proxmox VE 7.0 on a Dell Precision T7910 tying in my existing Ceph Nautilus storage for both RBD and CephFS use.
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 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.
