These are my notes on installing a second hand Lenovo ThinkPad T480 (20L6) for a relative of mine.
This is my braindump on setting up:
- Raspbian GNU/Linux 11 (bullseye) on a Raspberry Pi 4 Model B
- housed in an Argon ONE case with power button and fan
- USB audio to a Teufel Cinebar One+
- Playing music via DLNA
This is my braindump of shrinking the existing 1TB LVM cache (on a Samsung 960evo) to half size and using the freed up space to host qcow2 files used by our OpenShift 4 VMs
I bought a Blynclight PLUS busylight from Embrava, these are my notes on using it under Fedora Linux.

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