ZFS for Dummies
Damn good question. I don’t have time to search for duplicates myself right now, but you can look through/ask the mailing list: https://zfsonlinux.topicbox.com/groups/zfs-discuss (looks weird, but this is a legit web front end for the mailing list) and the github issues: https://github.com/openzfs/zfs/issues

zrepl: A one-stop, integrated solution for ZFS replication
There are definitely annoyances, but there are workarounds too; you can add additional vdevs to expand the whole pool if you want, and data is striped across them; it even lets you mix and match different raids if you really want to for some reason.
There's some current work to add a disk to existing vdevs, and I think even a semi-working PR for it now: https://github.com/openzfs/zfs/pull/15022. Hopefully in theory that will make ZFS a little less frustrating.

My SSD suddenly died. I only lost 10 minutes of data, thanks to ZFS
> the cost, besides having to actually create the file systems, is that moving data between them isn't instant.
No more the case after block cloning support goes production: https://github.com/openzfs/zfs/pull/13392

FreeBSD Bhyve Virtualization
I seem to remember zvol having known performance issues that were improved greatly in the latest openzfs release.
If you read https://github.com/openzfs/zfs/issues/11407
It should be in there somewhere

ZFS 2.2.0 (RC): Block Cloning merged
https://github.com/openzfs/zfs/pull/13392/files#diff-295f77b...
I believe it needs one such entry in RAM for each duplicated 128kB memory block. Not sure what sizeof(avl_node) is but likely around 32B. So in that case one brt_entry needs 48B RAM per 128kB data block.
One terabyte of deduplicated disk space thus needs 1e12/128e3*48 = 375MB RAM.
Also see this issue: https://github.com/openzfs/zfs/issues/405
> It is in FreeBSD main branch now, but disabled by default just to be safe till after 14.0 released, where it will be included. Can be enabled with loader tunable there.
> more code is needed on the ZFS side for Linux integration. A few people are looking at it AFAIK.
I don't think so. The memory management stuff is pretty well abstracted; on FBSD it just glues into UMA pretty transparently, it's just on Linux there's a lot of machinery for implementing our own little cache allocating because Linux's kernel cache allocator is very limited in what sizes it will give you, and sometimes ZFS wants 16M (not necessarily contiguous) regions because someone said they wanted 16M records.
The ZoL project lead said at one point there were a variety of reasons this wasn't initially done for the Linux integration [1], but that it was worth taking another look at since that was a decade ago now. Having looked at the Linux memory subsystems recently for various reasons, I would suspect the limiting factor is that almost all the Linux memory management functions that involve details beyond "give me X pages" are SYMBOL_GPL, so I suspect we couldn't access whatever functionality would be needed to do this.
I could be wrong, though, as I wasn't looking at the code for that specific purpose, so I might have missed functionality that would provide this.
