Motivation and Context

Fix ZED assert

Description

We would see zed assert on one of our systems if we powered off a slot. Further examination showed it returning a zfs_retire_recv() with a GUID of 0, which in turn would return a NULL nvlist. Add in a check for a zero GUID to prevent this.

How Has This Been Tested?

Manually verified this fixed the assertion.

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Performance enhancement (non-breaking change which improves efficiency)
  • Code cleanup (non-breaking change which makes code smaller or more readable)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Library ABI change (libzfs, libzfs_core, libnvpair, libuutil and libzfsbootenv)
  • Documentation (a change to man pages or other documentation)
