## You can use this to crush images in parallel via the shell alone.
## Make sure the GNU parallel utility is installed:
## - apt-get install parallel
## - yum install parallel

## For a simple example, run the following to simulate with echo and sleep:
## ls --color=no /usr/share/doc | parallel -j 16 --gnu -i -- 'sh -c "sleep 0.5 && echo {}"'
##   (-i tells parallel to substitute a filename when it sees {} in the command, rather than
##    simply appending it to the command, as it would normally do if you omit -i)

# Since Ceph's TRIM/discard support for the rbd kernel module driver has been
# an open TODO for half a decade, this script attempts to boot up a minimal
# Ubuntu QEMU+KVM guest to do such bidding. Due to mysterious raisins, librbd
# has discard support, whereas the rbd kernel module does not... and QEMU uses
# librbd, hence this wasteful script.
#
# On "decent" server hardware at home, this completes in just under 60sec for
# a 100GB rbd image.
