LVM cache in Fedora

From the man-pages: "The cache logical volume type uses a small and fast LV to improve the performance of a large and slow LV. It does this by storing the frequently used blocks on the faster LV. LVM refers to the small fast LV as a cache pool LV. The large slow LV is called the origin LV. Due to requirements from dm-cache (the kernel driver), LVM further splits the cache pool LV into two devices - the cache data LV and cache metadata LV. The cache data LV is where copies of data blocks are kept from the origin LV to increase speed. The cache metadata LV holds the accounting information that specifies where data blocks are stored (e.g. on the origin LV or on the cache data LV). Users should be familiar with these LVs if they wish to create the best and most robust cached logical volumes. All of these associated LVs must be in the same VG."

Assuming LVM is already setup in HDD (e.g. from anaconda) and SSD is untouched.

This list was originally present the wiki for this mailserver repository wiki page. I've created a gist with it as it is something that can be useful per se and I'd like to keep a copy of it.

A Feedback Loop (FBL) is a system by which an Internet Service Provider provides the sender a copy of the message that one of their subscribers has reported as spam — usually by hitting a “report spam” button in that ISP’s mail interface.

ISPs offer feedback loops to qualified senders, so the senders can identify subscribers who no longer want to receive similar mail and/or any problems originating from their networks, such as virus-infected spam-producing machines.

This page summarizes the information about FBL signup pages, whitelist pages, and postmaster pages of most popular ISPs around the world.
