The Btrfs (B-Tree) file system offers advanced management, reliability, and scalability features. It enables users to create snapshots, it allows for compression and integrated device management.
How to Create BTRFS FILE SYSTEM:
In order to make a basic btrfs file system, use the following command:
# mkfs.btrfs /dev/device
HOW TO MOUNT BTRFS FILE SYSTEM:
mount /dev/device /mount-point
HOW TO RESIZE A BTRFS FILE SYSTEM
Use command:
btrfs filesystem resize amount /mount-point
For example:
btrfs filesystem resize +200M /btrfssingle
To enlarge a multi-device file system, the device to be enlarged must be specified. First, show all devices that have a btrfs file system at a specified mount point:
btrfs filesystem show /mount-point
btrfs filesystem resize devid:amount /mount-point
btrfs filesystem resize 2:+200M /btrfstest
How to Shrink a btrfs File System:
Use Command:
# btrfs filesystem resize amount /mount-point
For Example:
# btrfs filesystem resize -200M /btrfssingle
# btrfs filesystem show /mount-point
# btrfs filesystem resize devid:amount /mount-point
# btrfs filesystem resize 2:-200M /btrfstest
