[LU-6867] change test-framework to detect active facet based on current Lustre state

Duplicate — Fri, 28 Jan 2022 17:00:21 +0000

Lustre failover tests can not be ran test-by-test (ONLY=1 replay-dual.sh && ONLY=2 replay-dual.sh) on the setup with ${facet}_HOST != ${facet}failover_HOST.
t-f keeps the "active" facet info in "${facet}active" files, which are created
when facet_failover() is executed first time in the test session.
Before facet_failover() executed these files are empty and
active facet is ${facet} by default.
In case when tests are executed test-by-test the active facet is
${facet}failover after 1st test completed, and 2nd test is started
having ${facet}failover active without this info stored in
${facet}active files.

It looks reasonable to detect active facet based on current state.
