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

A community build of Sailfish OS 3.4 for the Pro1 was released a month ago and I finally got around to flashing it.

These are my installation notes.

NOTE: DO NOT OTA UPDATE FROM 3.3 YOU MUST REFLASH

I bought a Blynclight PLUS busylight from Embrava, these are my notes on using it under Fedora Linux.

Since my ASUS PN50 is planned to be running MythTV, I reinstalled it with Fedora 32 (wiping my RHEL 8 install).

Specs say 115 x 115 x 49 mm (WxDxH). CD case in the picture to give you a rough idea of the size.

I bought an ASUS PN50.

These are my notes on initial bringup with Red Hat Enterprise Linux 8.2

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/
2020-09-09 19:28    686305280  s3://gitlab-backup/1599679709_2020_09_09_13.3.5-ee_gitlab_backup.tar

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.
