Resize dm-crypt mapping together with filesystem detected on
the device. The dm-crypt device must be recognizable by
Absolute number of filesystem blocks to be in the filesystem,
or an absolute size using a suffix (in powers of 1024). If
new_size is not supplied, the whole device is used.
On successful completion, the status code is 0. A status code of 2
indicates the operation was interrupted by the user. A status code
of 3 indicates the requested check operation could not be performed
because the filesystem is mounted and does not support an online
fsck(8). A status code of 1 is used for other failures.
Resize the filesystem on logical volume /dev/vg/test to 1000

will be unmounted prior the resize. All [y/n] questions will be
fsadm -e -y resize /dev/vg/test 1000M
