HP 3PAR arrays format their drives with 520 byte sectors, which are incompatible with standard operating systems. There are many guides online for reformatting 520 byte drives to 512 using sg_format , but HP 3PAR HGST drives with FIPS encryption (model HSCP0920S5xnFMRI) are particularly stubborn. The custom 3PAR firmware ( 3P02 ) blocks FORMAT UNIT and SANITIZE commands, and the FIPS TCG…
RedHat Enterprise Linux, and distrobutions based on it such as Rocky and Alma Linux, do not come by default with a kernel that supports BTRFS. This is easily added via a Special Interest Group (SIG) kernel repository, which supplies both a newer kernel release and the needed btrfs-progs package. Steps to install is simple: # Install the SIG RPM key. sudo rpm --import…
There are so many guides for copying to the clipboard from tmux to X11 and using the VI mode of tmux. I personally prefer to use the default mode with the default shortcuts. As such, I have looked and learned about using tmux list-keys which shows you existing short cuts to make my own to store in ~/.tmux.conf . To overwrite the default shortcuts: set-option -s set-clipboard off bind P…
After upgrade Fedora, every now and then, the Nvdia drivers fail and it falls back to open source drivers. Which is both nice, and annoying. Its nice because you can still use your computer, its annoying because anything that requires Nvidia drivers won't work. I have in the past fixed this by removing and re-installing the drivers, but today I decided to deep dive and find a proper fix to the…
In looking to setup load balancing of FreeIPA, there is not too much documentation on how to do this to where Kerberos authentication is successful. After lots of research, I found the key to making this work. Example haproxy config global chroot /var/lib/haproxy daemon group haproxy log /dev/log local0 info maxconn 200000 pidfile /var/run/haproxy.pid ssl-default-bind-ciphers…
If you plan on testing puppet autosign scripts , it is useful to generate test certificate signing requests (CSR) to verify that your script works. There is not much information online for this, so I had to go review documentation for extensions and requests . Below is what I have learned. CSR Configuration File First, you need to make your CSR config file for OpenSSL. You can use the example…
There does not appear to be any documentation on getting Nvidia support added to Docker or other container run times on Fedora 36, and it appears that Nvidia does not officially support Fedora with libnvidia-container repositories. I looked into this and found a solution to get Nvidia to work with Docker. Install Docker Community Edition The first step is to install the community edition of Docker…
I wanted to setup bridge networking with my main Arch Linux box so that I could connect to virtual machines in KVM. I was using the MACVTAP connection in Libvirtd, however that prevents you from being able to connect to the virtual machines due to the Linux host not knowing how to talk to the MAC addresses of the virtual machines with them being on the same interface card (…
I learned more about getting focus with my camera and used that knowledge to get these photos.
I feel that I have some sort of love for space which I have yet to release into the world.
