# This test proves that the plugin will leave the group when it cannot enable
|
|
# the read mode in the server.
|
|
#
|
|
# Test:
|
|
# 0) The test requires two servers.
|
|
# 1) Bootstrap group with server 1.
|
|
# 2) Restart server 2 with start_on_boot=1 (to enable it for the install).
|
|
# 3) Insert some data on server 1.
|
|
# 4) Uninstall and Install the plugin on member 2 (auto start enabled on 2)
|
|
# Use a debug point to make the read mode fail when connecting.
|
|
# 5) Verify that server 2 goes to ERROR state. Check that we cannot execute
|
|
# transactions.
|
|
# 6) Check all is fine after restarting group replication on server 2.
|
|
# 7) Clean up.
