I have not tried this scenario with RAID1 specifically. If you really want to get max performance, you might consider SSD storage or at least a direct passthrough of the disks. Since my lab equipment used for videos is a little older to start with, I'm not sure I can properly gauge performance with my current setup. This would likely be a question to ask directly to the Proxmox developers in their forums and/or submit a bug report. If you do track down the root cause of the issue, please share it so we can all be more informed. Thanks!
@@Practical-IT hey tnx for the quick response...yeah well to answer your 'max performance' comment well i'm using and older lenovo TS440 with a 4core xeon proc 3.6ghz 28Gb or RAM which should deliver somewhat, adequate performance...and add to that a harware RAID card running SAS drives...how would i go about for the 'passthough' ?
Thanks for the additional information Eric. I don't currently run my Proxmox servers with hardware RAID, so I'm not 100% sure how to boost the performance. I do have a couple of ideas that I would investigate if I were in your position. First in the Hardware tab of the VM check the selected "SCSI Controller." It defaults to VirtIO. You might want to try one of the RAID card options it lists in the drop-down. Next, Take a look at the "Hard Disk" option for the VM. In the advanced panel, it may be helpful to look at some of the options presented. With SAS drives, you may even want to toggle SSD Emulation. For pass-through options, I've normally seen this done on a whole disk and not necessarily with hardware RAID. I've included links to the Proxmox Documentation which should be helpful as well as a video I found that talks more about HDD passthrough. pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM) pve.proxmox.com/wiki/Storage ua-cam.com/video/2mvCaqra6qY/v-deo.html I hope this is somewhat helpful. If you do solve the performance issues I'd be very interested in what your approach ended up being.
have you tried to add zentyal as a VM, by itself, in proxmox? ...i feel mine is running slow in a RAID1 ext4 environment
