Check if amount of tables in databases is the same on each node - on step 2. Request list of tables for os databases on each node.
Check galera environment state - on step 2. Ssh on each node containing database and request state of galera

The root cause of the issue is that node-1, node-2, ... names can not be resolved on master node. If one adds them to /etc/hosts with the correct IP addresses, tests start to pass.

[Sergii Turivnyi (sturivnyi)]

Workaround:
    add entries for these nodes to /etc/hosts

@Sofia, how you deploy env if slave nodes were unreachable from master?

[Sofiia Andriichenko (sandriichenko)]

Nastya Urlapova, I have env, and I can give you access to it.

Hi team, it is known regression issue in MOS 9.0:

https://bugs.launchpad.net/fuel/+bug/1567957

we need to fix this regression issue or apply workaround in Sahara OSTF tests (to not use hostnames)

As far I understood from comment #5 issue was fixed, so this one was moved to Invalid.
