I have a situation where my unraid server is appearing to hang when I try stopping the array. I've noticed that disk to disk file copies take a lot longer than they should and performance is just not what I've experienced typically. I need to narrow it down but not really sure where to begin. I have attached diags of it currently. It's been trying to stop the array for several hours now.

I think it has to do with my effort to upgrade my drives to zfs. It’s induced some thing that I will have to manage differently. Right now copying data from drives to upgrade them to zfs and copy data back seems to be destabilizing everything.

Note that there's a known write performance issue when using zfs with the array, just the array, no issue with pools.

I think that is at least part of what I’m experiencing. Is this an issue that is being worked on and potentially resolvable or just something we need to live with due to the way zfs works?

I would hope for this to be fixed in the near future, but don't know if it's going to take weeks or months.
