The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs

Get/set ID3 meta tags using ffmpeg

A quick guide on how to read/write/modify ID3 metadata tags for audio / media files using ffmpeg.

FFmpeg has a free-form command line option that allows the user to specify key-value-pairs for encoding metadata. Let's take a look.

1. Read ID3 metadata

To list all global metadata tags for a media file, just set an input but no output file.

HP Smart Storage Admin CLI (`ssacli`) installation and usage on Proxmox PVE (6.x)

Why use HP Smart Storage Admin CLI?

You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.

CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.

ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.

Installation

Pre-requests:

TFTP server
IPXE Make sure ipxe.lkrn is in the TFTP root.
iSCSI target (Server) Assume we have an iSCSI target "1:net.cszombie.au:windows" that is ready to be connected. 1 is LUN id, "net.cszombie.au:windows" is the target name.
HTTP server (To speed up loading boot.wim, http is faster than tftp, http is supported by IPXE, however this is optional)

1. Download wimboot to the root of the TFTP server
