From bde3cce01783cd0c6874ad3ca700df2db9f720da Mon Sep 17 00:00:00 2001 From: Rajesh Madaka Date: Thu, 31 May 2018 20:26:47 +0530 Subject: Verifying max supported op-version and vol info file -> Create Volume -> Get the current op-version -> Get the max supported op-version -> Verify vol info file exists or not in all servers -> Get the version number from vol info file -> If current op-version is less than max-op-version set the current op-version to max-op-version -> After vol set operation verify that version number increased by one or not in vol info file -> verify that current-op-version and max-op-version same or not.
