    I bought an 800GB Intel NVMe SSD for my Proxmox VE host. In there I've got two pools, a hard drive pool and a SSD pool using old S3500's.

    Neither is too big. The hard drive pool is 2x6TB and the SSD pool is 4x 480GB. I'd like to use the NVMe SSD as L2ARC for both.

    Is there a way to do that? When I follow guides and use the NVMe for one pool I'm stuck. I can't add it as cache to a second pool.

    Partition and assign a partition as cache works.
    I assume you made sure that you in fact need l2arc and know about the impact on memory consumption ...
