Proxmox ZFS ARC Tuning — Optimize Cache for VM Performance
Set deterministic ZFS ARC limits, add L2ARC without wasting RAM on metadata, and tune recordsize and compression for your Proxmox homelab VMs.
ZFS on Proxmox — Pool Layout, Snapshots, and Backup Strategies
ZFS is the default filesystem on Proxmox VE for good reason — checksumming, snapshots, compression, and built-in replication. But “default” doesn’t mean one-size-fits-all. Pool layout, recordsize, snapshot cadence, and backup strategy all depend on your workload. This post covers the ZFS setup on my Proxmox host (SRV1), the snapshot pipeline, and how ZFS send/receive + sanoid handle retention and offsite recovery. Pool Layout System: HP ProDesk 600 G4 DM (i5-8500T, 32 GB RAM) Disks: 1× NVMe (OS + VMs), 1× SATA SSD (bulk storage) Boot/OS Pool — rpool Standard Proxmox installation creates rpool on the boot disk. No RAID, no redundancy — just a single NVMe: ...
