создать файловую систему btrfs (create a btrfs filesystem)
Описание (Description)
mkfs.btrfs is used to create the btrfs filesystem on a single or
multiple devices. <device> is typically a block device but can be
a file-backed image as well. Multiple devices are grouped by UUID
of the filesystem.
Before mounting such filesystem, the kernel module must know all
the devices either via preceding execution of btrfs device scan
or using the device mount option. See section MULTIPLE DEVICES
for more details.
The default block group profiles for data and metadata depend on
number of devices and possibly other factors. It's recommended to
use specific profiles but the defaults should be OK and allowing
future conversions to other profiles. Please see options -d and
-m for further detals and btrfs-balance(8) for the profile
conversion post mkfs.
