XFS is a high-performance 64-bit journaling file system created by SGI in 1993. It was introduced in the Linux kernel in 2001, XFS is supported by most Linux distributions, some of which use it as the default file system (RHEL/CentOS 7.0).

XFS excels in the execution of parallel input/output (I/O) operations due to its design, which is based on allocation groups, because of this, XFS enables extreme scalability of I/O threads, file system bandwidth, and size of files and of the file system itself when spanning multiple physical storage devices. A disadvantage of the XFS file system is that it cannot be shrunk, also metadata operations in have historically been slower than with other file systems, resulting in, for example, poor performance with operations such as deletions of large numbers of files. FAQ of xfs.org is a good place to read before you start implementing this filesystem.

Creating a new XFS partition
https://intensivegl270.weebly.com/blog/powerchart-for-mac-mojave. To create a new XFS file system you will first need a partition to format. You can use fdisk to create a new partition, like in the example below, you first need to invoke fdisk with the name of the harddisk you wish to create the partition on and then use 'n' command inside fdisk for a new parttion, after you have set the size like in the example below you will need to use the 'w' command to write the new table to disk.
You can find more info about fdisk here.
If the partition you want to format as xfs already exists on the system you must make sure it's not mounted by using the command umount command like this:
# umount /dev/sdb1
/dev/sdb1 should of course be replaced by the name of the partition you want to use.
Now that your partition is ready you can create a xfs filesystem by using the mkfs.xfs command, with the name of the partition you created like this:
# mkfs.xfs /dev/sdb1
Mounting the xfs filesystem
To mount the newly created partition you will have to first create a directory to be a mount point with the mkdir command, in our example we will use /mnt/db. Next you can mount the xfs parttion using the mount command as you would with any partition. Afterwards you can use the mount command to check if the partition was correctly mounted.
# mkdir /mnt/db
# mount /dev/sdb1 /mnt/db
# mount | grep /dev/sdb1
# mount /dev/sdb1 /mnt/db
# mount | grep /dev/sdb1
If you have environment with filesystem above 2 TB , you could try benchmark with mounting with inode64 option.
# mount -o inode64 /dev/device /mount/point
Fuse For Mac Os X
XFS enable write barriers to ensure file system integrity which preserves it across power failure, interface resets, system crashes by default. If your hardware have a healthy write cache feature then its recommended to disable write barriers otherwise performance would be negatively affected. You can disable write barrier using mount option below.
# mount -o nobarrier /dev/device /mount/point
Extending a xfs filesystem
You can see the size of the current mounted partitions using the following command:
# df -h
To extend a xfs filesystem you will first have to modify the partition table to the new size, you can do this similar to the way you created the partition using fdisk, first use 'd' command to remove the partition (be careful to select the correct partition if you have more then one on the device) then use the 'n' to create a partition of a bigger size, in our case 20GB.
Next all you have to do is run the xfs_growfs command with the -d switch (to grow the data part of the file system) and the filesystem will be grown to the new size of the partition.
# xfs_growfs -d /mnt/db
Note : Filesystem must be mounted for you to be able to use xfs_growfs and also that you can never shrink a xfs filesystem.

Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a 'bridge' to the actual kernel interfaces.
FUSE is available for Linux, FreeBSD, OpenBSD, NetBSD (as puffs), OpenSolaris, Minix 3, Android and macOS.[2]
FUSE is free software originally released under the terms of the GNU General Public License and the GNU Lesser General Public License.
History[edit]
The FUSE system was originally part of AVFS (A Virtual Filesystem), a filesystem implementation heavily influenced by the translator concept of the GNU Hurd.[3] It superseded Linux Userland Filesystem, and provided a translational interface using
lufis
in libfuse1.FUSE was originally released under the terms of the GNU General Public License and the GNU Lesser General Public License, later also reimplemented as part of the FreeBSD base system[4] and released under the terms of Simplified BSD license. An ISC-licensed re-implementation by Sylvestre Gallon was released in March 2013,[5] and incorporated into OpenBSD in June 2013.[6]
FUSE was merged into the mainstream Linux kernel tree in kernel version 2.6.14.[7]
The userspace side of FUSE, the libfuse library, generally followed the pace of Linux kernel development while maintaining 'best effort' compatibility with BSD descendants. This is possible because the kernel FUSE reports its own 'feature levels', or versions. Hp easy scan for mac os catalina. The exception is the FUSE fork for macOS, OSXFUSE, which has too many exceptions for sharing a library.[8] A break in libfuse history is libfuse3, which includes some incompatible improvements in the interface and performance, compared to the older libfuse2 now under maintenance mode.[9]
Operation and usage[edit]
A flow-chart diagram showing how FUSE works: Request from userspace to list files (ls -l /tmp/fuse) gets redirected by the Kernel through VFS to FUSE. FUSE then executes the registered handler program (./hello) and passes it the request (ls -l /tmp/fuse). The handler program returns a response back to FUSE which is then redirected to the userspace program that originally made the request.
To implement a new file system, a handler program linked to the supplied
libfuse
library needs to be written. The main purpose of this program is to specify how the file system is to respond to read/write/stat requests. The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with the kernel. If a user now issues read/write/stat requests for this newly mounted file system, the kernel forwards these IO-requests to the handler and then sends the handler's response back to the user.Unmounting a FUSE-based file system with the
fusermount
commandFUSE is particularly useful for writing virtual file systems. Unlike traditional file systems that essentially work with data on mass storage, virtual filesystems don't actually store data themselves. They act as a view or translation of an existing file system or storage device.
In principle, any resource available to a FUSE implementation can be exported as a file system.
Applications[edit]
On-disk file systems[edit]
Conventional on-disk file systems can be implemented in user space with FUSE, e.g. for compatibility or licensing reasons.
- Linear Tape File System: Allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives.
- NTFS-3G and Captive NTFS, allowing access to NTFS filesystems.
Layering file systems[edit]
FUSE filesystems can create a view of an underlying file system, transforming the files in some way.
- EncFS: Encrypted virtual filesystem
Archive and backup file systems[edit]
FUSE filesystems can expose the contents of archives or backup sets without having to first extract them.
- Borg (backup software): Deduplicating backup program that allows backup archives to be mounted as FUSE filesystems.
- Restic: Free, fast, efficient and secure backup software uses FUSE to be able to browse all of your backup snapshots as a regular file system
- SPFS A file system for Spectrum Protect, designed to mount the backup server filespace anywhere on your server, and use the features included from the backup server ( encryption, de-duplication, compression, filtrering etc). This is a WORM file system.
Remote/distributed file system clients[edit]
- CernVM-FS: A distributed read-only software distribution system, implemented as a POSIX filesystem in user space (FUSE) using HTTP transport, to deliver software in a fast and reliable fashion at global scale.
