Intro-To-Linux-Filesystems-[CornCon-5]-(September-2019)

##-===================================-##
[+] Intro To Linux Filesystems
##-===================================-##

## ------------------------------------------------------------------------- ##
[?] This presentation will be a live demo. (laptop recommended)
It will cover the use cases of ZFS, Btrfs, and XFS filesystems.
## ------------------------------------------------------------------------- ##

## ----------------------------------- ##
[?] In this talk I will cover:
## ----------------------------------- ##
> The ZFS Filesystem
> The Btrfs Filesystem
> The XFS Filesystem
## ----------------------------------- ##

##-=========================-##
[+] ZFS Filesystem
##-=========================-##
## ------------------------------------------------------------------------------------ ##
[?] The ZFS filesystem is an advanced fault tolarent filesystem (Self healing).
[?] Previously maintained by FreeBSD,
but recently the primary contributing project has become OpenZFS (Linux).
## ------------------------------------------------------------------------------------ ##
> ZFS ZPool - VDEVs (Virtual Block Devices)
> ZFS Copies - ZFS uses Ditto Blocks (Replicated Metadata).
It controls the number of copies of data stored for this dataset.
> ZFS Checksums - SHA256 Checksum Integrity Verification.
> ZFS Snapshots - Create, List, rolling back, delete, etc.
> ZFS Send+Receive - Replicate a filesystem or volumes between ZFS pools, or to remote locations.
> ZFS Snapshot Rollback - Reverts to a previous snapshot state.
> ZFS Clones - Clone an individual dataset.
> ZFS RAIDs - RAID-Z (4 Disks), Double-Parity RAID-Z | RAIDZ2 (5 Disks), Nested RAIDZ (8 Disks).
> ZFS ACLs - Create Access Control Entries (ACEs) for individual datasets.
> ZFS XATTR - Enable extended attribute properties for a file system.
> ZFS NoExec - Block process execution on the given dataset.
> ZFS Temporary Mount Points - Mount a directory as a temporary, throw away mount point.
> ZFS Compression - Compress individual datasets (lzjb | gzip | gzip-N | zle).
> ZFS Read-Only - Mount ZFS datasets read-only.
> ZFS Deduplication - The process for removing redundant data at the block-level.

##-=========================-##
[+] Btrfs Filesystem
##-=========================-##
## ----------------------------------------------------------------------- ##
[?] Btrfs is a modern copy on write (CoW) filesystem for Linux
aimed at implementing advanced features, while also focusing
on fault tolerance, repair and easy administration.

> Btrfs Creation - Mkfs.btrfs partition creation.
> Btrfs Compression (zlib, LZO)
> Btrfs Checksums - Checksumming on da
