instead of get_ceph_cmd_stdout(). Signed-off-by: Rishabh Dave <ridave@redhat.com> (cherry picked from commitc7c38ba558) Conflicts: qa/tasks/cephfs/test_mirroring.py - Commite4dd0e41a3was not present on main but it is now present on main as well as on Reef, which leads to conflict. - The line located right before one of the patches in this commit was modified in latest Reef branch, thus creating conflict when PR branch was rebased on latest Reef.
