# The purpose of this test is to validate that data read from a
|
|
# mapped rbd image is what it's expected to be.
|
|
#
|
|
# By default it creates an image and fills it with some data. It
|
|
# then reads back the data at a series of offsets known to cover
|
|
# various situations (such as reading the beginning, end, or the
|
|
# entirety of an object, or doing a read that spans multiple
|
|
# objects), and stashes the results in a set of local files.
|
|
#
|
|
# It also creates and maps a snapshot of the original image after
|
|
# it's been filled, and reads back the same ranges of data from the
|
|
# snapshot. It then compares the data read back with what was read
|
|
# back from the original image, verifying they match.
|
|
#
|
|
# Clone functionality is tested as well, in which case a clone is
|
|
# made of the snapshot, and the same ranges of data are again read
|
|
# and compared with the original. In addition, a snapshot of that
|
|
# clone is created, and a clone of *that* snapshot is put through
|
|
# the same set of tests. (Clone testing can be optionally skipped.)
