  1. OsX VM unable to write data to NAS properly

    I found something that seemed to fix my issues. Note that I changed for an Intel pro/1000 NIC passed through directly to the VM in the meantime, and still was experiencing the same exact problems (actually worse, as it would now kill the network card and needed a reboot to regain any internet...
  2. RAM consumption (Cannot allocate memory)

    Indeed L2ARC seems counter-productive knowing that my data is on a 3 SSDs raidz1 pool, I dont see how the additional ssd would help, or I got this wrong? As for RAM, at this point even if my motherboard supports up to 128GB (4 sockets), i'm currently decked at 64GB, and I don't really see how I...
  3. OsX VM unable to write data to NAS properly

    I tried something silly tonight, just to see if that would help: Setting the Rate limit to 80MB/s on the VM hardware network through the Proxmox GUI. Since it looked like a saturation of the network from the beginning before (but at the same time I had perfectly working hypervisor > Freenas...
  4. OsX VM unable to write data to NAS properly

    Ran more tests. It seems when I set a very small TCP window size that the connection runs smooth. Where could the issue come from? I am really not a network expert, any help would be appreciated... ./iperf3 -c 192.168.1.122 -w 2000 Connecting to host 192.168.1.122, port 5201 [ 4] local...
  5. OsX VM unable to write data to NAS properly

    Bump on this. I tried a LOT of things, including changing completely my Freenas hardware. I am still unable to find a solution. Realtek NICs, Intel NICs, nothing will do. The Proxmox server itself transfers to the NAS and communicates just fine with iperf tests, but the OSX vm does not. One...
  6. RAM consumption (Cannot allocate memory)

    If needed, I can get my hands on a spare 128GB SSD to use as cache it that would help with the whole thing in your opinion (Can I add L2ARC cache after the fact ?). I am quite happy of the performance of the whole setup so far despite that little issue, so I don't mind adding to it to make it...
  7. RAM consumption (Cannot allocate memory)

    On a side note, as long as I have roughly 2-3TB of disc space max on the system, giving zfs a max of 8GB should be plenty enough, correct? I don't have enough experience with ZFS to know what is acceptable or recommended, only info I found online about the 1GB memory = 1TB disc space rule...
  8. RAM consumption (Cannot allocate memory)

    Thanks for your help @LnxBil . Here is the out put root@serv0:~# arcstat time read miss miss% dmis dm% pmis pm% mmis mm% arcsz c 20:46:28 34 0 0 0 0 0 0 0 0 26G 26G I will study the wiki you linked to and see if I can sort it out that...
  9. RAM consumption (Cannot allocate memory)

    Hi, sorry for my late reply, I couldn't replicate the issue until now. Seems fine when I restart the server, but after a day or 2 of usage without turning it off, the problem appears again. Here is the output of free -g root@serv0:~# free -g total used free...
  10. RAM consumption (Cannot allocate memory)

    Hi everyone, First of, I am well aware of the famous "Linux ate my RAM" page and I post here because my issue makes no sense. I am also aware of the usual RAM requirements of 1GB per TB or storage for ZFS, but again, seems a bit odd in my situation. I have 5 VMs on my server, of which only...
  11. OsX VM unable to write data to NAS properly

    Maybe an important note, I tried running iperf3 from MacOSvm to NAS as UDP to test that as well, and that seems to work: MacOSvm >> NAS (via UDP) ./Downloads/iperf3 -c 192.168.1.45 -u -b 100m -t 10 -i 1 -f m Connecting to host 192.168.1.45, port 5201 [ 4] local 192.168.1.229 port 55382...
  12. OsX VM unable to write data to NAS properly

    Hi everyone, I am at an impass. After several iperf3 tests and Blackmagic write/reads, I realized all connections work fine from all the computers at home, except uploads/writes from my Macintosh VM to the NAS (freenas). As you will see below, I've ran tests from all points (Proxmox node...
  13. xrdp on Proxmox Host or workaround

    Is what I asked a stupid thing? I'm really new to the whole proxmox infrastructure so if I could get even a "forget about Linux QT or xrdp" from anyone, at least I know I don't need to look any further. Thanks in advance!
  14. xrdp on Proxmox Host or workaround

    Hi everyone, Been scratching my head around this as I progress into finding ways of controlling lights on my Proxmox home server. I found this nice piece of software from a very nice guy based on Asus Aura SDK: https://gitlab.com/CalcProgrammer1/OpenAuraSDK/ Upon discussing with him, I...
  15. RGB Control through a VM

    Yeah I kinda had a brain fart there, forgetting that the whole principle of qemu is to emulate the motherboard itself and virtualize it... :-D Which would obviously be my main bottleneck. I went through a crazy workaround and managed to get somewhere by installing Windows on a USB stick, boot...
