# WL11570 - GR: options to defer member eviction after a suspicion
#
# In a group of 3 servers, we crash one of them and test if the
# non-responding server remains in the group for the configured waiting time,
# instead of being immediately expelled.
# Test :
# 0. This test requires 3 servers
# 1. Create a group replication setup with 3 members
# 2. Set the group_replication_member_expel_timeout parameter to 30 seconds
# 3. Crash server 3 and it will restart
# 4. Then check if server 3 is still in the group
# 5. 30 seconds later, server 3 should still be in the group as UNREACHABLE
# 6. After 5 seconds, server 3 should have been expelled from the group
# 7. Restart GR on server 3
# 8. Server 3 should be back in the group
