14:27:41 fstransform: fstransform will move '/dev/mapper/centos-home' contents into the loop file.
14:27:41 fstransform: WARNING: THIS IS IMPORTANT! if either the original device '/dev/mapper/centos-home'
or the loop device '/dev/loop0' become FULL,
YOU WILL LOSE YOUR DATA !
fstransform checks for enough available space,
in any case it is recommended to open another terminal, type
watch df /dev/mapper/centos-home /dev/loop0
and check that both the original device '/dev/mapper/centos-home'
and the loop device '/dev/loop0' are NOT becoming full.
if one of them is becoming full (or both),
you MUST stop fstransform with CTRL+C or equivalent.
this is your chance to quit.
press ENTER to continue, or CTRL+C to quit:
