zfs 2.3.0

[plato79]

Well,

It's released today and it brings with it a lot of good features:

• RAIDZ Expansion (#15022): Add new devices to an existing RAIDZ pool, increasing storage capacity without downtime.
• Fast Dedup (#15896): A major performance upgrade to the original OpenZFS deduplication functionality.
• Direct IO (#10018): Allows bypassing the ARC for reads/writes, improving performance in scenarios like NVMe devices where caching may hinder efficiency.
• JSON (#16217): Optional JSON output for the most used commands.
• Long names (#15921): Support for file and directory names up to 1023 characters.
• Bug Fixes: A series of critical bug fixes addressing issues reported in previous versions.
• Numerous performance improvements throughout the code base.

Hope it's implemented in Proxmox soon.

Still not implemented:
* User happy secure pool import (without cannot...) after power failures.
* Better iops handing for raidz/draid configs for use cases like hypervisor image stores (without the need to config only useful mirrors).
* Implementation of consumer friendly disk handling so that pve doesn't eat them in zfs root installations.

I'm really excited to see how Proxmox integrates the Direct I/O stuff.

I assume (with little practical experience and less understanding than I'd like) that Direct IO should passively improve the performance of guests stored on NVME pools without much/any tuning needed from the user, aside from just turning it on.
