# This test validates the behavior of the group replication recovery channel
|
|
# against common slave commands like START/STOP/RESET SLAVE.
|
|
#
|
|
# Test:
|
|
# 0. The test requires three servers: M1, M2 and M3.
|
|
# 1. Bootstrap start group replication on M2. Add some data for recovery.
|
|
# Start M1.
|
|
# 2. Stop replication on M1. On M2 lock a table to block recovery. Start M1.
|
|
# 3. Execute a STOP SLAVE command and see the recovery channel still active.
|
|
# 4. Execute a RESET SLAVE ALL command and see the recovery channel is not
|
|
# affected on M1 when GR node is active.
|
|
# 5. Kill the server M1. The recovery channel should still be there but it's
|
|
# not started. Recreate the slave channel to test that it started
|
|
# 6. Clean the created channels and tables.
