Won't Do

Description

Downgraded PXC 5.7.24 to PXC 5.7.20 will result to failed SST from 5.7.24 donor to 5.7.20 joiner. See attached logs from pxc1 and pxc2. Upgraded pxc2 back to 5.7.24 and it works.

 

 

How to repeat:

  • create table t1 (id int primary key auto_increment, s varchar(100)) engine=innodb;

  • insert data

  • downgrade on node to PXC 5.7.20

  • insert data on one of PXC 5.7.24 nodes to trigger the IST when 5.7.20 rejoins

  • start PXC 5.7.20 node

Environment

PXC1 - version 5.7.24

PXC2 - version 5.7.20 (downgraded from v5.7.24)
