Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ZFS 2.2.0 (RC): Block Cloning merged
I use it in Kubernetes via https://github.com/openebs/zfs-localpv
The PersistentVolume API is a nice way to divvy up a shared resource across different teams, and using ZFS for that gives us the snapshotting, deduplication, and compression for free. For our workloads, it benchmarked faster than XFS so it was a no-brainer.

OpenEBS on MicroK8S on Hetzner
Last few months I experimented more and more with all OpenEBS solutions that fit small Kubernetes cluster, using MicroK8S and Hetzner Cloud for a real experience.
- Openebs ?? Or equivalent

Network Storage on On-Prem Barebones Machine
I would investigate https://openebs.io/ https://portworx.com/ https://longhorn.io/ if you are forced to you can mount ISCSI on the kublet and feed it to one of those solutions. Keep in mind most of the big guys buy some sort of managed solution that you can point a CSI like trident https://netapp-trident.readthedocs.io

Ask HN: What are some fun projects to run on a home K8s cluster?
What are some cool projects to self hosted on a home Raspberry Pi (64 bit) Kubernetes cluster (Helm charts). arm64 support is a must. A lot of projects only build amd64 Docker containers which don't run on my cluster.
I currently run:
- obenebs (provides abstraction for using local k8s worker disks as PVC mounts when running on-prem) -- https://openebs.io/
-
Finally got around to doing that Ceph on ZFS experiment
I didn't set anything actually -- I need to look into whether OpenEBS ZFS LocalPV can facilitate passing ZVOL options (I don't think it can just yet). The only tuning I did on the storage class was the usual ZFS-level options.

My self-hosting infrastructure, fully automated
What do you use to provision Kubernetes persistent volumes on bare metal? Iām looking at open-ebs (https://openebs.io/).
Also, when you bump the image tag in a git commit for a given helm chart, how does that get deployed? Is it automatic, or do you manually run helm upgrade commands?

Building a "complete" cluster locally
Ideas from my kubernetes experience: * Cert-Manager is very popular and almost a must-have if you terminate SSL inside the cluster * Backups using velero * A dashboard/UI is actually very helpful to quickly browse resources, client tools like k9s are fine too * Secret: Management: Bitnami Sealed Secrets is the second big project in that space * I would add Loki to aggregate Logs * Never heard of ory. Usually I see (dex)[https://dexidp.io/] or keycloak used for Authentication * I like to run OpenEBS as in-cluster storage. * Istio isn't compatible with the upcomming ServiceMeshInterface (i think), so the trend seem to go toward Linkerd * Some Operator to deploy your favorite Database, is also a nice learning exercise.

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]
