NFS performance
Then to improve things you ought to balance the vdevs - which you can do with core. https://github.com/markusressel/zfs-inplace-rebalancing (Thats one way)

My unassuming 152 TB ZFS NAS
I know I'm giving up a lot of space by not using raidz, but I like the ease of growing the pool 2 disks at a time and I'll probably rebalance soon with this script. Yes, I'm aware raidz expansion is a thing now, but it's not quite ready yet and even when it's merged, it'll still have unattractive limitations.

finally extended my pool with a 2nd vdev tonight

Ubuntu 24.04 LTS is so buggy you can't install the OS [video]
Be careful if you use ZFS-on-root, make sure not to snapshot bpool or it will brick your system and require a complete reinstall.

Radxa's SATA HAT makes compact Pi 5 NAS
> The only non-junk PCIe3 option that's even advertised here recently is the overpriced WD Red SN700.
Those WD drives seem to have some real issues, at least with ZFS and btrfs. :(

DiskClick: Ever wanted to hear Old Hard drive sounds
IMO the "next fs" is just zfs. They somewhat recently merged RAIDZ expansion feature https://github.com/openzfs/zfs/pull/12225 and make regular improvements. If no file system has what you need today, zfs will probably be the first one to have it "tomorrow," imo.

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.

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]
