# Bug#24901077: RESET SLAVE ALL DOES NOT ALWAYS RESET SLAVE
#
# Problem:
# =======
# If you have a relay log index file that has ended up with
# some relay log files that do not exists, then RESET SLAVE
# ALL is not enough to get back to a clean state.
###############################################################################
# Remove all slave-relay-bin.0* files (do not remove slave-relay-bin.index)
# During server restart rli initialization will fail as there are no
# relay logs.  In case of bug RESET SLAVE will not do the required clean up
# as rli is not inited and subsequent START SLAVE will fail.
# Disable "Warning  1612  Being purged log ./slave-relay-bin.0* was not found"
# because it is different on Unix and Windows systems.
