🌗 使用 ZFS、iSCSI 與 PXE 實現無碟 Linux 開機
➤ 擺脫實體磁碟束縛，透過網絡實現靈活的 Linux 部署
✤ https://aniket.foo/posts/20260505-netboot/
本文記錄了一種利用網絡啟動技術（PXE/iPXE）取代實體硬碟安裝 Debian 的方案。作者透過在 NAS 或伺服器端建立 ZFS ZVol 作為區塊設備，並透過 iSCSI 協議將其掛載為遠端磁碟。此架構不僅解決了在遊戲 PC 上安裝 Linux 可能破壞 Windows 開機引導（GRUB）的問題，還省去了維護實體 USB 安裝碟的麻煩。透過設定 DNSMasq 將引導請求指向 TFTP 伺服器，系統啟動時會自動載入 netboot.xyz 選單，進而掛載 iSCSI 目標並進行作業系統安裝與執行。這是一個適合開發者在不幹擾現有 Windows 環境下，靈活調用 Linux 資源的高階技術實作。
+ 這對於在 Windows 遊戲機上測試實驗性環境非常有幫助，不用再擔心 Wind

🎉 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? 😂

Отказоустойчивый кластер виртуализации KVM на Astra Linux

Импортозамещение, уход вендоров, требования регуляторов, безопасность — причин переезжать с продуктов Microsoft и VMware сегодня хватает. Но важно, чтобы это было осознанное инженерное решение, а не реакция по принципу «лишь бы уйти». Тем более что далеко не всегда есть смысл переплачивать за продукт, который для вашей инфраструктуры избыточен. В статье разбираю, как собрать отказоустойчивую виртуализацию на базе Astra Linux: DRBD + GFS2 + Pacemaker против Ceph. Отказоустойчивый кластер KVM на Астре

I finally solved my zfs-on-iSCSI systemd quandry:

# cat /etc/systemd/system/zfs-iscsi-import.service
[Unit]
Description=Trigger ZFS import after iSCSI availability
After=cloud-init.target
Wants=cloud-init.target

[Service]
Type=oneshot
ExecStartPre=/sbin/modprobe zfs
ExecStart=/bin/systemctl start zfs-import.target
RemainAfterExit=yes

[Install]
WantedBy=default.target

For the longest time #Backblaze hasn't supported the backup of networked drives, but has supported #iSCSI. Sadly, and annoyingly quietly, v9.2.2.878 of the client killed iSCSI support, so my array is now blocked.

I'd have liked some notice, but okay. The new setup (local drives, iSCSI as local backup) is now working with much better small file handling, and thankfully the data deduplication worked perfectly, so no re-upload required.

Hey fedi, is LUKS over iSCSI over the web a good idea?

Usecase would be personal storage for mostly media.
Exclusive mount is not really an issue, but still feels kinda meh.

My main concern is: does this work good enough in practice over not super-reliable links?
secondary: does it perform well enough?

Are there other setups with data encrypted on client that do not statically leak a ton of metadata like file structure?

What is NVMe Storage?

NVMe, or Non-Volatile Memory Express, is a modern access and storage protocol for flash-based solid-state storage. Designed for low overhead, latency, and response times, it aims for the highest achievable throughput. With NVMe over TCP, NVMe has its own successor to the familiar iSCSI. While commonly found in home computers and laptops (M.2 factor), it is designed from the ground up for all types of commodity and enterprise workloads. It guarantees fast load times and response times, even […]
