After doing some searching, this seems to be a huge no-no in ZFS (which to me seems like a serious design flawin ZFS, but that's a rant I'll save for another day). Anyway, if this new feature would help me remove the missing device and bring the zpool back to life (I never wrote anything to the pool after adding the device), that would be awesome!
    This Issue turned Feature talks about it and it links to the OpenZFS roadmap item.
    Describe the problem you're observing Adding a device to a pool causes the device to be bound to the pool forever in most cases since removal of the device requires recreation of the pool without the device to be removed. While it's comm...

    Not gonna happen, Fuse will never be as performant since most of it resides on userspace and is in no way related to dkms, in fact they can even move to Fuse and still require dkms because the code is out of tree.

    I think what you wish is for Zol to be integrated on the main tree but i dont think that could happen license wise until Oracle stop being asshats
    yup, I would like it to be in kernel, I think some (ubuntu?) moving it to...

    Nothing, it just me I just don't like it to be there, I understand why it is there and what it is for, but still, there are some things you just do not like...

    For example: bad weather (like raining or -25C), but still those things are good and "healthy" from other point of view

    Has cache that doesn't clear after reboot been implemented or in the works? It's been on Solaris for years.

    What you mean by ACL, as far as i'm aware they are working

    zroot aclinherit passthrough local
    zroot xattr sa local
    zroot acltype posixacl local

    or you mean another type of ACL that is not supported yet?
