    L2ARC, PCi/SSD

    I'm sure this question has been asked before, but I can't decide what would be best. More RAM, and additional L2ARC - and in that case which type? Proxmox is currently running on a HP DL380 G9 with one PCI-E slot available, so I could get a card that supports NVMe and add around 250 GB fast...

    Best to store VMs/CTs in zpool or in separate datasets?

    I have a single NVMe drive for Proxmox to boot from. I'm going to add 2x SATA enterprise SSDs to my host, create a ZFS mirror, then move my VMs/CTs to that mirror. Is there any benefit from having separate datasets for VMs and CTs (like below), or should I put everything on the pool itself...

    What are the best practices for snapshotting zvol based VMs

    I might not be searching the correct terms, but I haven't really found any information on ways to manage snapshots for VMs running in zvols on ZFS. - Our system runs VMs on a zpool, and I let PVE automatically create a new zvol for each VM. - I have setup zfs-auto-snapshot to take incremental...

    3rd-party ZFS auto-snapshot scripts - Am I doing something dangerous as far as PVE is concerned?

    I use Proxmox to host a bunch of container and VMs, but I also have created some other (non-pve-related) ZFS pools/datasets on my PVE host. I was exploring 3rd-party scripts for automatically creating snapshots of these datasets (specifically this one...
