  1. I changed my RAID configuration. For anyone interested: 4x WD RED 3TB HDDs in RAID 5 dd if=/dev/zero of=/volume1/homes/lan/testx bs=4096M count=1 conv=fdatasync oflag=direct 0+1 records in 0+1 records out 2147479552 bytes (2.1 GB) copied, 19.9718 s, 108 MB/s
  2. Unfortunately my problem starts one hop earlier. I asked this question because I want to have a VM which is connected via VPN and is able to run another (Virtualbox) VM in it. So basically what I need is nested virtualization. Has anyone got this working in DSM? I tried it with VMM from Synology and Virtualbox but no matter which operating system I use as soon as I try to add a VM in virtualbox in the nested VM I get this message: "Invalid Settings Detected" System : Acceleration page On the host (DSM 6.2) cat /sys/module/kvm_intel/parameters/nested is giving me "N" as
  3. Does anyone know a workaround for this? The same spk runs fine in 6.2.3

  5. @amikot was asking me how to implement a RAMDISK in DSM and I found this guide. So many thanks to mark and as usual I don't accept any liability for any data loss or damage caused by using this tutorial(s). I wrote a little script which adapts to your environment and asks if you would like to specify the amount of RAM in percent or GB the amount of RAM which should be used for the Ramdisk an existing folder where your RAMDISK should be created. E.g. /volume1/ramdisk You have to save the following lines as "" run it, answer the questions
  6. RAM disks aren't new to me, but I didn't know that DSM supports it. I already found a guide on how to implement it. I guess for read-only it would be fine but the SSD adviser reported that I have 25GB of "hot" and 1TB of "warm" storage. Unfortunately the recommendation for a SSD cache is 170GB and my CPU only supports 64GB RAM total. I will buy Samsung PM883 SSDs and will let them run in RAID1 (with checked "skipping sequential I/O" box).
  7. Thanks, now I get it. I know my SSD choice wasn't the best but it was at the beginning for testing purpose only. What du you think, is it better to replace the drive with a synology SAT5200 or would it be enough to buy a samsung pro ssd?
  8. I used two used Samsung EVO 256 GB SSDs as SSD Cache for about one year and a half. Now DSM notified me about the SSDs estimated lifetime reaching end. When looking at the values of my SMART tests I am unsure what to believe. As far as I know DSM predicts the lifetime based on the Wear_Leveling_Count. However when comparing the SMART values those two SSDs makes it unclearer for me. DSM reports this SSD is OK, although the "raw value" is way higher than the limitthreshold whereas this SSD should be replaced So is there a possib
  9. At the start I didn't saw the advantage of docker but a few month later I can't imagine running DSM without it. In the screenshot you can see just a few containers I run. The containers with lan- as prefix are for developing websites. One of the biggest pros which got me into docker was pi-hole and lancache. If you would like to know more about those two you can have a look at this:
  10. Your CPU supports 25 TDP-down and I think @IG-88assumed you actived it since you want to lower power consumption. IF your Mainboard supports undervolting you need to be carefully. I reduced my voltage in 10 mv steps until it got my system unstable when CPU stress testing and added 40 mv to this value. E.g. 1,1 volt is default value, 910mv is where it gets unstable and you set it to 950. This method assumes you have a fix Vcore. But in theory it also works with adaptive or offset. BTW I forgot to mention that my NAS runs lots of docker containers and one of the
  11. I don't think so. I am running DSM baremetal on an i3-8100 and as far as I know the hardware choices is where you can save energy most easily. Meaning you can lower comsumption mostly by choosing a power efficient CPU and put only drives in your NAS you need, because every HDD needs power as well. You could however undervolt your CPU slightly if the motherboard allows it. I hooked a power consumption measuring device (MyStrom wifi) between my NAS and my wall socket. It is a pretty cool device which offers an API to grab the current power draw and can be integrated in Netdata (if you are into t
  12. I only had once an incident where someone from russia tried to login in my NAS in Austria multiple times and then got blocked automatically by DSM. After that I changed my firewall settings inside DSM so that only ports from the services I need are allowed and restricted it just to my country. My point is as @IG-88 already mentioned when you follow the instructions you should be safe.
  13. I didn't need all 30 till today, but in case anyone is interested and doesn't want to fiddle around with docker try ssh on your NAS and editing the openvpn.conf of your server/NAS. I guess you could increase the clients by setting max-clients 30 to something higher. See for yourself: vi /var/packages/VPNCenter/etc/openvpn/openvpn.conf
  14. @IG-88glad I could help. Yeah I don't like noisy server either
  15. I am not sure if it fit your needs but have a look at those:
