When checking the state of a Clustrix node, we do so in steps:Z
- Is Clustrix installed
- Is Clustrix running
- Can Clustrix be accessed using root
- Can Clustrix be accessed using the test user
and deal with a failure at each point.
Implementations of check_replication() and start_replication() for Clustrix allows to use fix_replication()
also for Clustrix nodes without checking it.
Also several attempts to check nodes after restart are added - to wait for nodes if they are not running
right after server daemon restart
