Description

several ha.sh defects found during wide ha testing :
1.
I.e. if stop file is created before ha_repeat_mpi_load() "while" is started – we have :

ha.sh: line 399: (1476438773 - start_time) / nr_loops: division by 0 (error token is "nr_loops")

2.
in hard failover mode (pm -0 <node>) some node could be down at the time when ha.sh collects the lustre logs.
In this case we have test passed but returns 255 at the end :
stdout :
