Using a zvol for a swap device for host and VMs



Swapping to Optane

Since i’m running virtual machines, there is another thing which should go to low-latency storage: swap. I try to conserve as much memory as possible, which means VMs sometimes use their swap space, which gets horribly slow in case it resides on spinning disks. For that reason i created another partition, created a separate ZFS pool and created disk images that will hold the VMs swap.

Creating a new pool is very simple and as i don’t need redundancy on swap it will just be one “device”, actually a partition. Using unique hardware identifiers instead of device paths (e.g. “/dev/nvme0n1p3”) is quite helpful as PCIe enumeration and partition order may change.

I have just check some of the ones we have configure and that are working in the field. I have attached IPOE and PPPOE configurations. I hope this helps. If you need any help with debugging please let me know.
