Observed

Additional Information 

======================

parted releast version: (2.3)

error message: 

Assertion (last_usable <= disk->dev->length) at ../../../libparted/labels/gpt.c:934 in

Error: The backup GPT table is not at the end of the disk, as it should be.  This might

mean that another operating system believes the disk is smaller.  Fix, by moving the backup

to the end (and removing the old backup)?

parted: invalid token: unit

Fix/Ignore/Cancel? Fix                                                    

Warning: Not all of the space available to /dev/dm-0 appears to be used, you can fix the

GPT to use all of the space (an extra 1024 blocks) or continue with the current setting?
