SOLVED: I decided to mount both drives directly on a Open Media Vault VM per Pass Through stop VM nano /etc/pve/qemu-server/.conf scsiX: /dev/sdX start VM And in there create a Mirror RAID and then an SMB Share. Performance is okayish starts good with 250MB/s then drops to ~100MB/s constant
I'm currently migrating from an rpi4b with mounted drives from an 4bay NAS to a proper virtualized environment Hardware: i5 7400 16GB RAM 250GB nvme OS drive, 2x1TB ZFS Mirrored HDDs 2.5 Gbit/s Ethernet
I want to use Proxmox as a Hypervisor, in there I want to run VMs one will be Open Media Vault as my Fileserver and "SAN" for Docker Container like Immich (with cifs mount like the current setup). But the current issue is when Transfering a File the transfer speed close to the end of a 5GB file drops to 0Mbit and stays there for a time and ramps up again. Checking directly with dd if=/dev/zero of=/path/to/mirror/test1.img bs=8G count=1 oflag=dsync provides ~1GB Writes which can't be right in a mirror HDD (ran both inside the OMV VM and Proxmox host with similar results and yes the path was adjusted to reflect the mirrored drives not the nvme) Is there a way to see why its dropping, any logs than I can look for? Or any other suggestions for better setup as I also tried truenas in the past as a VM but got horrible performance aswell.
Changeing ashift sizes Setting up mirror -> expectation about 250MB read speed constant Actual Result -> Initial 250MB then dropping to 0
