I have been using XCP-NG for 4 months and I am facing a read/write speed issue.
When I created my hypervisor physical server, I decided to build a RAID 10 array to improve speed and redundancy. Unfortunately, I discover that what was the bottleneck on my infrastructure was Virtual Drives. I made different tests in order to come to that conclusion. (Network, with/without RAID, local copies).
It might sound evident for you but was not the case for me
Is it possible to install an NFS server directly on xcp-ng (not on a VM) in order to avoid this virtual drive speed issue ? If yes, is it not recommended for security issues for example ?
If you have other ideas to solve my problem don’t hesitate !
I think I could build a second machine only for my NFS but I would have to spend money again. And it would result in having 2 physical servers in my house…
Thank you for your reply. I managed to get a physical machine and install a “RAID 10” with ZFS. I am now trying to configure NFS with Kerberos correctly.
But I have just one more question, sometime in Lawrence Systems YouTube videos, VM’s disks are stored on NFS via XOA, but result with this is the same as if I store the VM on local hard drives right ? Because what I will store on NFS is still Virtual hard drives, so I will still have this virtual hard drives speed issues ?
(I’m currently planning to mount NFS storage from my VM system directly)
Thank you for your reply.
But you still have this hard drive virtualization layer ? If you look at your files in your NAS, it’s all virtual drives, not files right ?
