Diskless Debian Boot with ZFS, iSCSI, and PXE: A Technical Guide
By
Aniket
Pure flour-power. Hearty enough to carry you through lunch.
Summary
A technical guide on setting up a diskless Linux (Debian) boot system using ZFS, iSCSI, and PXE/Netboot.xyz. The author describes their motivation for offloading OS storage to a network drive to free up local NVMe space for AI model storage, outlines the server setup using a single Debian 13 server for all services (Netboot.xyz, TFTPD, iSCSI Target, ZFS ZVol), and notes performance limitations while explaining that OS performance is not critical since models run from local storage and RAM.
Key quotes
· 3 pulledInstalling Debian on a network drive will indeed be noticeably slower than a native install.
Since I'm going to use some portion of my local NVMe drive to store & load the models, I didn't really care about the OS performance as I have enough RAM to run everything smoothly once the OS has booted up.
A single Debian 13 based server is used for Netboot.xyz, tftpd, iSCSI Target & ZFS ZVol.
