# BUG#21162660 - CRASH AFTER FAILURE IN RELAY-LOG-RECOVERY, ON START GR COMMAND
#
# This test checks that a server restart with relay-log-recovery set to 1 will
# not cause any error during recovery as the group_replication channels are
# not used for this purpose.
#
# Test:
# 0. The test requires two servers: server1 and server2.
# 1. Setup group replication on two servers and make them ONLINE.
# 2. Restart server1 with relay-log-recovery=1. Then, check that on starting GR
#    server doesn't crashes.
# 3. Assert check that start GR doesn't purge relay logs.
# 4. Restart server1 with relay-log-recovery=0. Then, check that on starting GR
#    server doesn't crashes.
# 5. Assert check that start GR doesn't purge relay logs.
# 6. Check number of members in the group is 2. Add some data on server1 and
#    validate that same data is available in server2.
# 7. Clean up.
