Can someone tell a dummy like me, if this impacts truenas core?
- It's hard to tell because I get this:
  
  root@truenas[~]# zpool get version poolname
  
  NAME PROPERTY VALUE SOURCE
  
  poolname version - default
- There is a thread going on at https://www.truenas.com/community/threads/silent-corruption-with-openzfs-ongoing-discussion-and-testing.114390/
  
  Some users are reporting that it does affect Truenas (though it depends on the use case).
- TrueNAS-13.0-U6 (the current core version)
  
  zfs version reports 2.1.13
  
  so it should be clean.
