  • Status changed from new to assigned

Working on this, trying to get the "Force 4K" option to work with GPT.

  • Resolution set to fixed
  • Status changed from assigned to closed

Fixed this for now. Disabled the Force4K option when using GPT since its a dirty hack and mangles partition stuff :(


Once we get a "native" way to set 4K mode or ashift=12 in ZFS, we will re-enable this option.
