LegoHouse Posted March 20 Share Posted March 20 (edited) Hi all, I am running UnRaid on a QNAP TVS-471 with 20TB x 6 - Seagate Exos x20. I'm not running ZFS on Unraid, I'm using the storage in Unraid to store the disks on Proxmox Containers & VMs via NFS. I'm also mounting the NFS shares into the VMs to write files in other shares, I noticed that the performance is incredibly slow which causes the VMs on Proxmox to run slow or at times not boot well. I reckon there is a bottleneck somewhere but not sure how to diagnose it properly. Here is some additional information. 3 Nodes on Proxmox running HA Dell OptiPlex Micro Form Factor 7010 i7-12700 64 GiB DDR4 1TB NVMe Storage Server QNAP TVS-471XT UnRaid 6.12.8 i7-8700T CPU 64 GiB DDR4 20TB x 6 - Seagate Exos x20 - (1 Parity) 2TB NVMe for Cache The 3 nodes and Storage are connected to a Unifi 1G Switch. I'm sure there are optimizations that I need to do but not sure where to start. Edit - Writing this down, I can see that the Optiplex standard NIC and the Switch could potentially be the bottleneck, I wonder if I upgraded the Nics to a 10 gig and get a unifi switch aggregator or a smaller 10 gig switch for the devices if that would resolve it? Before that I'd like to confirm if there any other optimizations that I need to do Edited March 20 by LegoHouse Quote Link to comment

LegoHouse Posted March 20 Author Share Posted March 20 (edited) 27 minutes ago, trurl said: https://docs.unraid.net/unraid-os/manual/storage-management/#array-write-modes Thanks for the prompt response! I read through this and I enabled the cache on the shares that Proxmox is using to use Cache and move them to the array, I'll try to run the VMs again to see if there is a difference Reading more on this, I do think I did not setup my cache drive properly for the Proxmox related shares and setting the docker containers running on Proxmox to read of the cache, I'll try to read more into this Edited March 20 by LegoHouse Quote Link to comment
trurl Posted March 20 Share Posted March 20 Cache and many other things are discussed on that page of the documentation, but the direct link I gave was not about cache. Please read the exact section I linked. Quote Link to comment
