Description

conf-sanity test_30b takes into account only "fake nid" and does not take into account a failover_nid configured for "--failnode".
This leads test always fails on the setup with ost1failover_HOST != ost1_HOST.
Example of failure :
configuration used :

ost1_HOST=fre812
ost1failover_HOST=fre811

test fails with :

Updated after 2s: wanted '192.168.108.32@tcp' got '192.168.108.32@tcp'
failover_nids: [ 192.168.108.12@tcp, 192.168.108.11@tcp, 192.168.108.32@tcp ]
should have 2 failover nids: 3
 conf-sanity test_30b: @@@@@@ FAIL: Failover nid not added

NIDCOUNT is equal 2 only if ost1failover_HOST is default (equal to ost1_HOST). In this case failover_nids expected to contain OSTNID and NEW :

failover_nids: [ <OSTNID>, <NEW> ]

For case ost1failover_HOST != ost1_HOST NIDCOUNT is equal 3 because failover_nids also contains failover_nid configured for failover node (192.168.108.11):

failover_nids: [ <OSTNID>, <ostfailover nid>, <NEW> ]
failover_nids: [ 192.168.108.12@tcp, 192.168.108.11@tcp, 192.168.108.32@tcp ]'
