ZFS for Dummies
I’m on the other end of the spectrum. I like knowing the flags and settings I use to create the pools.
For snapshots and replication take a look at sanoid (https://github.com/jimsalterjrs/sanoid).

Automatic container snapshots? cv4pve or zfs for a small homelab?
I use a combo of PBS and ZFS with Sanoid. The ZFS snapshots are nice because you define it all in a config file with frequent, hourly, daily, weekly, monthly snaps retained however you want. Importantly I use that on the root pool as well as my data pools. With PBS I have a custom retention config and have it backing up VMs and LXCs every couple hours. The PBS dedupe functionality makes it possible to keep full backups going back ages with minimal storage consumption, just the changed blocks. PBS is running inside a VM yes, but it’s storage is on another pool.

New to ZFS, what layout to choose for 4x20TB drives?
No, it's written by the developer of Sanoid and Syncoid. The foremost open source ZFS snapshotting tool. He contributes on this sub all the time.
- Python Port of 600 Line Bash Script: rsync-time-machine.py for Rsync Backups
- Ask HN: Why isn't BTRFS the default FS in home-oriented Linux distributions?
-
Way to extract/see what TrueNAS does behind the GUI?
If you’re looking for snapshot and sync management check out sanoid/ syncoid. Jim’s a mod on r/zfs if you need any help but it’s pretty straight forward. https://github.com/jimsalterjrs/sanoid
- Have you made ZFS volumes yourself and did any of them experience data corruption?
-
Setup a backup system if you haven’t done it yet
There also is sanoid https://github.com/jimsalterjrs/sanoid/ for zfs and btrfs users
-
Do I need zsys or are there alternatives?
You probably do want regular automated snapshots, even if not of specific datasets. I'd recommend my own tool Sanoid for that: https://github.com/jimsalterjrs/sanoid/ ; you can configure it to snapshot the datasets you want snapshotted in the ways you want them snapshotted and nothing else.

Minimum ZFS delegated permissions for Syncoid
The section at the bottom seems to go into your question in pretty good detail, but there’s also an item about this in the Sanoid/Syncoid wiki here: https://github.com/jimsalterjrs/sanoid/wiki/Syncoid.

A data corruption bug in OpenZFS?
https://github.com/openzfs/zfs/issues/15526#issuecomment-181...
> zpool get all tank | grep bclone
> kc3000 bcloneused 442M
> kc3000 bclonesaved 1.42G
> kc3000 bcloneratio 4.30x
> My understanding is this: If the result is 0 for both bcloneused and bclonesaved then it's safe to say that you don't have silent corruption.
It's a very rare race condition, odds are very low that you were impacted. If you were, you would have noticed (heavy builds with files being moved around where suddenly files are zero).

Ask HN: What's your "it's not stupid if it works" story?
A couple years ago, I had an idea for convincing a filesystem to go faster using 2 compression steps instead of one. I couldn't see why it wouldn't work, and I also couldn't convince myself it should.
It seems to have worked out. [1]

ZFS Profiling on Arch Linux
https://github.com/openzfs/zfs/issues/7631
This is a long-standing issue with zvols which affects overall system stability, and has no real solution as of yet.
More details on this discussion: https://github.com/openzfs/zfs/issues/6824#issuecomment-1817... . Basically he is too busy to continue developing the encryption features but is able to review the related works.
There is also discussion about using ZFS on LUKS in the same thread: https://github.com/openzfs/zfs/issues/6824#issuecomment-1819...
ZFS on top of LUKS seems to have it's own issues though. :(

Tell HN: ZFS silent data corruption bugfix – my research results
https://github.com/openzfs/zfs/pull/15529#pullrequestreview-...
Honestly, ZFS is the best thing on the (Free)BSDs only... On Linux it doesn't even use the page cache, and you conflict severely with L2ARC. I know there's a variety of people who don't care, but still for real users it's not an actual option.

In OpenZFS and Btrfs, everyone was just guessing
A more "correct" fix has been posted https://github.com/openzfs/zfs/pull/15615
Current Master: https://github.com/openzfs/zfs/blob/acb33ee1c169bf1c1f687db1...
When I look up the problem, I could only see the issue being discussed, and probably leading to that commit, and then it was not in my current release (2.1) despite several years later. I’m wondering if ZFS still holds that high standard for reliability.
What are some alternatives?
