Filesystem and other data format management.
Usage:
%(cmd)s list [--all] [ <device> ...]
%(cmd)s create [ --label=<label> ] <fstype> <device> ...
%(cmd)s delete <device> ...
%(cmd)s list-supported
Commands:
list List filesystems and and other data formats (RAID metadata, ...)
on given devices.
If no devices are provided, all filesystems are listed.
If --all option is set, all filesystem, including system ones
like tmpfs, cgroups, procfs, sysfs etc are listed.
create Format device(s) with given filesystem.
If more devices are given, the filesystem will span
over these devices (currently supported only by btrfs).
For list of available filesystem types, see output of
%(cmd)s list-supported.
delete Delete given filesystem or data format (like partition table,
RAID metadata, LUKS, physical volume metadata etc)
on given devices.
list-supported
List supported filesystems, which can be used as
%(cmd)s create <fstype> option.
