This single M.2 drive is currently set up as the cache drive, with the intent to store virtual drives for VMs and any Docker file storage needs. We formatted it ZFS, assuming newer is better, but I would have used btrfs previously for cache drives. We are still using XFS for the Array drives.

I'm helping my son set up unRAID on a new server (Core i7-13700K, 32GB RAM, Solidigm P44 Pro 2TB SSD cache, 3x4TB protected array). He plans to run a bunch of VMs, including his primary Windows workstation, passing through an Nvidia 3070 GTX video card. I've used unRAID for more than 10 years, but ZFS support is a new feature. We don't plan to set up a ZFS pool with multiple drives, just a single PCIe 4 M.2 drive. Which file system is best for this use case? I know ZFS supports advanced features, but I'm mainly interested in good performance for his virtual machines. Can anyone offer first-hand knowledge of performance benefits / penalties for ZFS over btrfs for this scenario? Thanks! -- stewartwb

I appreciate the info on compatibility - thanks! I found the direct GIT URL by searching this thread, and all is good. One server upgraded to 6.6, the other is on its way.

Quick question - I stayed on the sidelines for a while - still running version 6.3.5. I'm ready to upgrade, and I would like to run Fix Common Problems / Upgrade Assistant. However, I get an error installing the current plugin, since it doesn't support such an old version of unRAID. I've also tried to install the Community Applications plugin, but I get the same error. Is there a way to install the last version of FCP that still works on unRAID 6.3.5? If not, I'll just wing it, checking everything manually. Thanks!
