I wonder if #OpenBSD will ever get a modern fs. They even jettisoned FFS softdeps because IIRC they said that Kirk McCusick was the only one who understood the code (which very well may be true).

I don't think we'll ever see #ZFS on OpenBSD; the resource usage and code complexity is kind of anathema to them, and I totally get it.

I wonder if HAMMER2 would be a good fit, then? I must confess that don't know anything about it.

💥 OpenZFS 2.4.2 Released With Linux 7.0 Kernel Support, Many Bug Fixes - Phoronix

｢ Most notable with the OpenZFS 2.4.2 release is adding support for the stable Linux 7.0 kernel where as up to now the prior point release only supported through Linux 6.19. Support back to the distant Linux 4.18 kernel is maintained. On the FreeBSD side, FreeBSD 13.3 and newer continue working with this OpenZFS code ｣

There are many opinions and combinations possible, of course. I prefer simple, community backed, and solid foss blocks that interoperate. That converged to:
* #debian for base OS
* data on encrypted #zfs
* #incus for VM and system containers management (formerly LXD)
* #ansible for automation, with the debops collection

Infrastructure for people, to solve our problems and at our scale, with all the tools under direct control of worker sysadmins

Actually, I did. Well, it was the default. ;)

It's... slow? Feels slow. But that's ok.

btrfs is absolutely "WE HAVE #ZFS AT HOME" and that's ok. 🤣

After being hosed by #btrfs on #linux 7.0.1, the #atomdrift postgresql master database is on #OmniOS & #ZFS

It's good to be back, even if I'm rusty in Solaris-based environments.

🎉 In the latest episode of "Things No One Asked For", our hero bravely attempts to boot #Linux #diskless using #ZFS, #iSCSI, and #PXE just to avoid messing with Windows. Because clearly, the only logical solution to not wanting to clutter your #gaming PC with toolchains is to summon the unholy trinity of ancient network boot protocols. 🥳 Honestly, why not just run Doom on your fridge while you're at it? 😂

This weekend I finally had some time to get my TrueNAS server up and running with Immich on it.

Now my photos are replicated across two devices and the only thing I need now is the remote backup, which it will be another TrueNAS server at the office.

Also, it's the first time I had the guts to delete all my photos from Google Photos.

Производительность софт NVMe рейдов на основе mdadm, LVM и ZFS при использовании iSER и NVMe-oF (100G version) — Part 2

Продолжение первой части, смысл данной статьи сохраняется, а именно показать максимальную производительность, когда вопрос сохранности данных решается репликами или бэкапами. Цель - протестировать производительность трёх систем объединения физических устройств в одно логическое систем при использовании iSER и NVMe-oF. Так как статья получилась объёмная, она поделена на 2 части. В этой части - тесты с использованием HCIbench и iSER\NVMe-oF

Is there a way on #ZFS or #BTRFS to create a file that is the concatenation of two files?
So, cat a b > ab, but only taking up metadata?
Is the best way to just do the write and then ask the kernel to deduplicate it, and pray that it doesn't flush to disk in the meantime?
This would be really useful for serving smaller chunks of packages on #NixOS or #Guix, but also potentially on other distros as well, or even for general download optimization. (cc #bittorrent ?)

edit: Thanks, apparently there is an ioctl for this:

New article: Inside ZFS 🔥

A walk through the three layers (SPA, DMU, DSL), the 128-byte block pointer that makes the whole pool a Merkle tree, the uberblock ring, and why snapshots are O(1).

👉 https://internals-for-interns.com/posts/zfs-filesystem/

#ZFS #Filesystems

@archivist_Liz @Thorsted I'm working on de-embedding / resolving binary headers of file-formats to filesystem objects in #zfs.

To physically normalize + demystify binary file formats #ForGood into "common related filesystem objects" (with IDs).

It's like #LEGO for data.

Would you know anyone interested in a project on that? My R&D on that is pretty far already. Very interesting and useful results!

All #FOSS. #RightClickEditMetadata on anything.

Spent the weekend deep in ZFS internals 🤓

Next up in the filesystems series: how a 128-byte block pointer turns the entire pool into a Merkle tree, and why snapshots are basically free (just copy a pointer + stamp a TXG).

SPA ↔ DMU ↔ DSL, uberblocks, vdevs, ARC, ZIL.

Drops Monday

Not me, every time I set off a `zpool scrub` (with apologies to TLC):
🎵
Yes, I just want to scrub,
A scrub is a kind of check that gets love from me,
Countin' out the checksum of your best friend's drive,
Trying to verify at me

New post on The Byte Architect:

**Filesystem Wars: Why Your Choice of Storage is Actually a Security Move**

This is not a “which filesystem should I use?” checklist. It is a walk through the ideas behind FFS, BFS, NTFS, ext4, ZFS, and APFS — and why storage design is never just about storage.

Crash consistency, journaling, soft updates, CoW, snapshots, encryption, space sharing: different filesystems solve different problems, and those choices shape reliability, usability, and security.

The real target, of course, is APFS.

There's something that #ZFS #OpenZFS does at mount time (I'm told it's processing deferred frees) that sometimes takes an incredibly long time (hours), and I'm still struggling to understand: why must this be done at mount? (And why mount and not pool import?) Why can't it continue to be deferred like it was during operations?

Still waiting for `zfs mount -a` after an unplanned power outage, 90 minutes after restore.

Unpopular opinion: I have fought with ZFS under Talos for months, but in reality what I needed was Longhorn.

Yeah, yeah, I now, different things. But that's just to say that ZFS is not the silver bullet that some people try to convince you of.

@freya I am trying out #ZFS on my "homelab" server but was most surprised that it seems one has to do all the ZFS setup external to the #flake which only lives within the manually made ZFS pool environment. That seems to mean I need a sort of orchestration script like tool to match flake /persist data settings (am using #impermanence lite currently) to the ZFS setup hoo-ha. Works fine but is not declarative #nixos at all really. Any ideas there ?
