10.04.2021 · Proxmox is a great open source alternative to VMware ESXi. ZFS is a wonderful alternative to expensive hardware RAID solutions, and is flexible and reliable. However, if you spin up a new Proxmox hypervisor you may find that your VM's lock up under heavy IO load to your ZFS storage subsystem.

Normally you only add L2ARC if you cant add ram AND cache hits are too low. Is there a real gain using a ssd cache for zfs for a storage pool?

I was wondering, If I got a decently large NVMe m.2 SSD and used it as the install/root drive for Proxmox, could I partition a sizable chunk of it off as a SSD Cache for the ZFS pool? IE: If I got a 1TB NVMe SSD (like a Intel 660p), could I use say 50GB for root, xGB for storage/etc and then up-to 500GB as an SSD cache?

Hi guys. I see so many questions about ZFS and thought i would make a very short guide to understand the basic concepts about ZFS and how it is used in Proxomox. I separate it into these 3 levels: #### Level 1: Pool ( zpool command ) ####. A zpool is a storage space composition of one or more disks in stripe (raid0), mirror (raid1) or raidz ...

Everything except the base Proxmox install is stored on my 3x 1TB RAIDZ-1 array, so I figured it made more sense just to use the caching built into ZFS.
