From c5d17bc3c29f4a0772858e4b6a4819ea3e040521 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Mon, 23 Oct 2017 09:45:59 -0700 Subject: [PATCH] Emit history events for 'zpool create' History commands and events were being suppressed for the 'zpool create' command since the history object did not yet exist. Create the object earlier so this history doesn't get lost. Split the pool_destroy event in to pool_destroy and pool_export so they may be distinguished. Updated events_001_pos and events_002_pos test cases. They now check for the expected history events and were reworked to be more reliable.
