Attempts to resize other filesystem types will fail. XFS Will only grow if mounted. Currently, the module is based on commands from util-linux package to perform operations, so resizing of XFS is not supported on FreeBSD systems.
How to add another DASD disk to LVM and resize a btrfs filesystem onto it. Steps. We assume the disk has already been made available to the system.

Btrfs is a new file system for Linux, one that is still very much in development. Although I wouldn't exactly describe it as "experimental" any more, it is, as stated in the Wiki at kernel.org .If btrfs check --repair errors out with "couldn't open RDWR because of unsupported option features", you can try clearing the space cache with btrfs check --clear-space-cache v2 or btrfs check --clear-space-cache v1, and retrying the btrfs check --repair.. YMMV. If you break it, you own the pieces, and by the time you need --repair chances are that it broke .

Thanks to help from cwillu and mig at freenode, I figured out the solution. The btrfs filesystem resize command just like resize2fs resizes the filesystem, but keeps the partition limits unchanged. These can be changed using the fdisk to delete the btrfs partition and then recreating it with an endpoint which is slighty less than 20Gb smaller . In this guide I will walk you through the installation procedure to get an Ubuntu 20.04 system with a luks-encrypted partition for the root filesystem (including /boot) formatted with btrfs that contains a subvolume @ for / and a subvolume @home for /home.

This method is considered the safest and most reliable way of mounting a plain old block device. To find a UUID, simply run the blkid command. # blkid /dev/sda1. /dev/sda1 UUID= "15983cac-77bc-46b1-9f79-cb180e438a64" TYPE= "ext4". Your fstab now looks more like this, using UUID to identify the filesystem we wish to mount: UUID = .Saved searches Use saved searches to filter your results more quickly
Enlarging a btrfs File System. To enlarge the file system on a single device, use the command: # btrfs filesystem resize amount / mount-point. For example: # btrfs filesystem resize +200M /btrfssingle Resize '/btrfssingle' of '+200M'. To enlarge a multi-device file system, the device to be enlarged must be specified.
