Doc Text:
Block volumes created on CNS version 3.9 or below use default Asymmetric Logical Unit Access (alua) group setting at target side configuration. These are meant to be used with 'prio const' at the initiator side multipath.conf. After upgrading OCS to 3.10 or above, the new recommendation at multipath is 'prio alua'. Old block volume having target side alua group set to default are not compatible with newly recommended multipath.conf. Hence, to maintain compatibility of old block volumes with the new multipath.conf recommendation, the default alua group should be changed to glfs alua group. With this update, the block volume target configuration is generated automatically as part of the upgrade to fix the comparability issue. And Hence, the compatibility of old block volume with the new multipath.conf recommendation is maintained.

Description Prasanna Kumar Kalever 2018-10-13 19:52:52 UTC 
Description of problem:

At OCS-3.11 it was decided to include genconfig steps as part of upgrade time guidelines [1]. But we fear that users might miss this step.

Hence we want to run genconfig command as part of guluster-blockd systemd units ExecStartPost option.

Setting the qe_test_coverage flag as '-' as this looks like umbrella bug based on comment 16.
