*OS:* Fedora | *Component:* parted-3.4-2.fc34.x86_64
*parted mode: *interactive
*Target device:* 256 MiB USB-storage
*Starting state:* existence alone of partition table; then no partition.

Hello.

   - The creation of partition table and naming of partition when supported
   by selected partition table, succeed.
   - The creation of filesystem fails.

# parted /dev/sdc
(...)
(parted) mkpart primary ext4 0% 100%
(parted) quit
Information: You may need to update /etc/fstab.

*Note:* Unknown instruction in regards to mention "*You may need to update
/etc/fstab*".

# parted /dev/sdc
(parted) print
Model: Kingston DataTraveler 2.0 (scsi)
Disk /dev/sdc: 255MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number  Start   End    Size   Type     File system  Flags
 1      1049kB  255MB  254MB  primary               lba
 (parted) quit

For example, here is a Gparted v.1.3.1 interpretation:
"Unable to detect file system! Possible reasons are:
- The file system is damaged
- The file system is unknown to GParted
- There is no file system available (unformatted)
- The device entry /dev/sdc1 is missing"

parted does not create filesystems, to do that you need to run mkfs.ext4
on the new partition. The partition value in parted is to tell parted
what you plan to use it for so that it can setup the UUID or partition
type correctly.

Good to know. That turns unexpectedly that report into the most common
observable issue, which has root in documentation and
descriptions.commands. Of course from the analyse of  relevant materials,
manual PARTED(8) and parted's interactive interface "(parted) help", the
obvious is noticeable; yur depicted description is there missinge.

$ man parted
mkpart [part-type name fs-type] start end
                     Create a new partition. part-type may (...).

# parted /dev/sdc
(parted) help
  mkpart PART-TYPE [FS-TYPE] START END     make a partition

Here is the relevant information in this regards, though documented lately
in the logical information chain. Its reading may for that very reason
easily be missed:

# parted /dev/sdc
(parted) help mkpart
(...)
 'mkpart' makes a partition without creating a new file system on the
partition.  FS-TYPE may be specified to set an appropriate partition ID.

That's precisely within manual PARTED(8) and parted's interactive interface
"(parted) help" that information of first class relevance are dully
expected to be documented. What a pity it has not been according to that
principle since 2007 March 29 till nowadays. Regards.
