# Test:
# 0. The test requires two servers: M1 and M2.

# Check that a member with binlog_checksum= NONE can join a group
# with binlog_checksum= CRC32.
# 1. Set binlog_checksum to CRC32 and start GR on server1.
# 2. Set binlog_checksum to NONE and start GR on server2.
# 3. Commit data on both members, all is OK.
# 4. Validate that server1 binary log has checksums.
# 5. Validate that server2 binary log does not have checksums.
#
# Check that a member with binlog_checksum= CRC32 can join a group

# 6. Set binlog_checksum to NONE and start GR on server1.
# 7. Set binlog_checksum to CRC32 and start GR on server2.
# 8. Commit data on both members, all is OK.
# 9. Validate that server1 binary log does not have checksums.
# 10. Validate that server2 binary log has checksums.
#
# 11. Clean up.
