+# @brief Toolbox to manage Ceph cluster dedicated to testing
+#
+# Example use case:
+#
+# ~~~~~~~~~~~~~~~~{.sh}
+# source ceph-helpers.sh
+#
+# function mytest() {
+# # cleanup leftovers and reset mydir
+# setup mydir
+# # create a cluster with one monitor and three osds
+# run_mon mydir a
+# run_osd mydir 0
+# run_osd mydir 2
+# run_osd mydir 3
+# # put and get an object
+# rados --pool rbd put GROUP /etc/group
+# rados --pool rbd get GROUP /tmp/GROUP
+# # stop the cluster and cleanup the directory
+# teardown mydir
+# }
+# ~~~~~~~~~~~~~~~~
+#
+# The focus is on simplicity and efficiency, in the context of
+# functional tests. The output is intentionally very verbose
+# and functions return as soon as an error is found. The caller
+# is also expected to abort on the first error so that debugging
+# can be done by looking at the end of the output.
+#
+# Each function is documented, implemented and tested independently.
+# When modifying a helper, the test and the documentation are
+# expected to be updated and it is easier of they are collocated. A
+# test for a given function can be run with
+#
+# ~~~~~~~~~~~~~~~~{.sh}
+# ceph-helpers.sh TESTS test_get_osds
+# ~~~~~~~~~~~~~~~~
+#
+# and all the tests (i.e. all functions matching test_*) are run
+# with:
+#
+# ~~~~~~~~~~~~~~~~{.sh}
+# ceph-helpers.sh TESTS
+# ~~~~~~~~~~~~~~~~
+#
+# A test function takes a single argument : the directory dedicated
+# to the tests. It is expected to not create any file outside of this
+# directory and remove it entirely when it completes successfully.
+#

-#! @file ceph-helpers.sh
-# @brief Toolbox to manage Ceph cluster dedicated to testing
-#
-# Example use case:
-#
-# ~~~~~~~~~~~~~~~~{.sh}
-# source ceph-helpers.sh
-#
-# function mytest() {
-# # cleanup leftovers and reset mydir
-# setup mydir
-# # create a cluster with one monitor and three osds
-# run_mon mydir a
-# run_osd mydir 0
-# run_osd mydir 2
-# run_osd mydir 3
-# # put and get an object
-# rados --pool rbd put GROUP /etc/group
-# rados --pool rbd get GROUP /tmp/GROUP
-# # stop the cluster and cleanup the directory
-# teardown mydir
-# }
-# ~~~~~~~~~~~~~~~~
-#
-# The focus is on simplicity and efficiency, in the context of
-# functional tests. The output is intentionally very verbose
-# and functions return as soon as an error is found. The caller
-# is also expected to abort on the first error so that debugging
-# can be done by looking at the end of the output.
-#
-# Each function is documented, implemented and tested independently.
-# When modifying a helper, the test and the documentation are
-# expected to be updated and it is easier of they are collocated. A
-# test for a given function can be run with
-#
-# ~~~~~~~~~~~~~~~~{.sh}
-# ceph-helpers.sh TESTS test_get_osds
-# ~~~~~~~~~~~~~~~~
-#
-# and all the tests (i.e. all functions matching test_*) are run
-# with:
-#
-# ~~~~~~~~~~~~~~~~{.sh}
-# ceph-helpers.sh TESTS
-# ~~~~~~~~~~~~~~~~
-#
-# A test function takes a single argument : the directory dedicated
-# to the tests. It is expected to not create any file outside of this
-# directory and remove it entirely when it completes successfully.
