15:24:46 fstransform: preliminary steps completed, now comes the delicate part:
15:24:46 fstransform: fstransform will move '/dev/nvme0n1p4' contents into the loop file.
15:24:46 fstransform: WARNING: THIS IS IMPORTANT! if either the original device '/dev/nvme0n1p4'
or the loop device '/dev/loop11' 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/nvme0n1p4 /dev/loop11
and check that both the original device '/dev/nvme0n1p4'
and the loop device '/dev/loop11' 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:
15:25:24 fstransform: moving '/dev/nvme0n1p4' contents into the loop file.
15:25:24 fstransform: this may take a long time, please be patient...
