LVM it's probably fine with. Raid, MUCH less so. What you need to make |

sure does NOT happen is a lot of random writes. That might make deleting |

an lvm snapshot slightly painful ... |

But adding a SMR drive to an existing ZFS raid is a guarantee for pain. |

I don't know why, but "resilvering" causes a lot of random writes. I |

don't think md-raid behaves this way. |

But it's the very nature of raid that, as soon as something goes wrong |

and a drive needs replacing, everything is going to get hammered. And |

SMR drives don't take kindly to being hammered ... :-) |

Even in normal use, a SMR drive is going to cause grief if it's not |

handled carefully. |
