  1. I have the processor iGPU enabled in the bios. unRAID boots off that and I can see the output fine for the unRAID log from that HDMI connection. The 780ti is in the first PCIe x16 slot and is not assigned to unRAID. I simply make it available to the VM on the template screen along with its sound card. It all works fine in my Win10 VM (which is stopped at the moment). It is just the Linux Mint VM which is giving the typical Mint/nvidia black screen boot problems that were usually resolved by adding nomodeset parameter to the grub boot screen. I simply cannot get past the black screen when I give the 780ti to Mint in the Linux template. I can see output from grub - I can edit the grub options... I just can't get the Mint installer to load through the 780ti.
  2. I have erased that VM and started again. 1. When I assign the VNC GPU, I can complete the installation properly but of course have no nvidia drivers available for the discrete GPU. 2. If I assign the discrete nvidia GPU and try to create a new VM, I see the bios splash, get the grub menu and can 'e' to add the nomodeset parameter to the options. Regardless of whether I try the main or compatibility boot, if I 'ctrl-x' to proceed with the boot, I just get a solid black screen with no blinking cursor. Pressing ctrl-alt-del will reboot the session and bring me back to the bios then grub screen. Nothing I have tried will allow me to proceed. Any help please? EDIT : Adding nvidia.modeset=0 to the options in grub menu passes the solid black screen, shows the small Mint logo with dots for a few seconds then gives the blank screen with blinking cursor. It doesn't get past that though.
  3. Could someone point me to a guide to install a Linux Mint VM when you have an nVidia GPU please? I am hitting the "black screen on boot" issue that seems to plague nVidia cards. If I pass the nVidia GPU to the VM I don't even get the grub menu to add the nomodeset parameter. If I use the VNC GPU then I do get grub and can get into the desktop and install but cannot add the nVidia drivers. I am stumped.
  4. I would appreciate some advice on which specific sound card is recommended for use with unRAID and a gaming VM using headphones. I have a small under monitor sound bar which works perfectly in the VM and is fine for casual stereo sound when my wife and I are listening to a YouTube video together but the majority of my listening and gaming is done with a pair of Grado SR60 headphones. The reason I am asking is that first I noticed that my onboard sound would not break out into its own IOMMU group. From a forum search I understand this is an issue on some Skylake and Kabylake boards (ASUS Maximus IX Formula in my case). The warning when starting the VM is clear that it is the group the onboard sound is in. Next I thought to try my external Roland Quad Capture over USB since it has a headphones monitor socket. I quickly discovered that the audio was faint and very, very distorted. I checked the Roland support site and saw the disclaimer of "This driver cannot be used in a virtual Windows environment, such as Hyper-V or Virtual PC." Damn, there goes that idea. I am now at the position of needing a PCIe sound card. I do have a spare PCIe 3.0 x1 slot on the motherboard so please could you suggest something. The main brands I have in front of me at Scan in the UK are ASUS and Creative. ===================================== EDIT : Thread title changed and method for solving detailed below I have managed to pass through my Roland Quad Capture successfully to the VM and get rid of the poor, choppy sound from it. Thanks to gridrunner in his YouTube video on how to pass a USB controller to the VM, it works perfectly. In the video he makes a comment about how external sound cards generally prefer to be on a stubbed USB controller that has been passed to the VM rather than just being handed to the VM directly. This was the key to getting the Roland working. Once I stubbed my PCIe USB controller in the syslinux file, rebooted, set the USB mode in the VM to XHCI (3.0) and gave the whole controller to the VM, all issues with the Roland ceased and it behaved as expected. Thanks, gridrunner - you saved me from buying a sound card!
  5. If you have the share as "cache prefer" it will fill the cache first then overflow to the array until Mover can sort it out. If the share is "cache only" it will only use the cache until it is full then stop.
  6. Lee - SpaceInvaderOne covers this in his unRAID Introduction to VMs video... I have just started this video myself as I am working through setting up a Win10 VM for the first time.
  7. It was really hard to measure the temperature in the X2M case as the card was just above the PSU and facing downwards. I have moved the card over to the main machine now and can get a better look at it through the side panel.
  8. Good suggestions, thanks. I have one spare SATA port on the old machine that I can use to put the new cache SSD temporarily.
  9. FOR SALE : Six WD Red 3Tb (WD30EFRX) drives CLEARED : Yes, all drives have been cleared and zeroed SMART : See attached LOCATION : United Kingdom only POSTAGE : FREE (Royal Mail Special Delivery) COST : All six drives are being sold as a set. I will not split the set. I would like £50 each, so a total of £300 secures all six drives. PAYMENT : PayPal only, email on request. Returns accepted within 14 days in appropriate packaging, buyer pays return shipping. These drives have been pulled from my current NAS due to an upgrade and have been lightly used with between 7600 and 7800 Power On hours. They have been owned by me since new and were purchased from Scan.co.uk. They are all zeroed and are ready for your array. Also included in the package will be two extra FREE drives that I no longer require - a WD Green 1Tb and a WD Green 500Gb. Any questions, just ask. Daniel. TAKEN : No Longer available.

  10. Doesn't Plex have some sort of metadata file with the thumbnails and tags that you picked for your movie collection? Where does that reside? So far I have moved over the movies themselves and installed a fresh Plex docker onto the new NAS.
  11. I am in the process of setting up a duplicate of my unRAID NAS and would like to know how to move my Plex settings and metadata over from the old array to the new one. Both machines are running unRAID 6.3.5. Both have the movies in exactly the same folder structure as I have already duplicated the media. Both are actually running the exact same Dockers (Plex and Krusader). Once I have migrated Plex over to the new array, the old one will have the Plex Docker stopped. Is there a guide or FAQ that has this information?
  12. I am trying to get my head around how the user interface on an unRAID machine with VMs is used when you want to change from one VM to another and how the machine handles sleep, both of the VM and the unRAID machine itself. Given the following configuration, could you answer any of the questions below please? Hardware : i7 7700K with iGPU, one 780ti GPU, one monitor with multiple inputs, keyboard with sleep key (fn-F12), iPad unRAID setup : NAS serving Plex stream, VM1 as lightweight Linux machine on virtual iGPU, VM2 as Windows 10 gaming machine on main GPU, only one active VM at a time. Sleep rules : the unRAID machine must be available to serve Plex when asked but can spin down HDDs when not in use and should sleep using the sleep plugin after 30 mins when no Plex user and no VM user. The active VM should be able to sleep when not in use for a short while or be hibernated if not needed for a long time. Note : while the monitor has multiple inputs (HDMI from iGPU, DP from main GPU), I have to select them via a button on the monitor bezel and an onscreen menu. Monitor will wake to the last used input. I have space in the machine for a secondary physical GPU and also a spare input on the monitor. === Situation A : Stop and Start usage. I am using VM1 for light browsing but get called away from the PC for a while. On a bare metal machine I would normally press the keyboard sleep key to force sleep, deal with the situation then return and press a key to wake. What do I do here to achieve the same result? Situation B : Stop using for long interval. I am using VM1 for light browsing and get to the end of the day. I would like to sleep the VM and also allow unRAID to enter sleep after a while. I will not resume usage till the end of the day. Assuming unRAID is asleep when I return, what do I have to do to wake up both unRAID and the VM? Situation C : Switch to gaming VM. I am using VM1 for browsing then decide to change over to the gaming VM2. What do I have to do in order to hibernate VM1 (so that it releases CPU cores and RAM) and then activate the gaming VM2? === Thanks in advance for the help. If you think I should rearrange my machine or would benefit from different hardware (such as second discreet GPU or a KVM), feel free to make suggestions. This will be running on my main PC in the sig below where I have 4x8Tb drives and an unRAID USB ready to go. The SAS9201-8i will probably move over to this machine.
  13. It is a good suggestion but I actually have a second bank of four 8Tb drives going through preclear now. In a few days I will have my main machine acting as the active NAS/VMs with the "old" NAS acting as backup. Both machines will have 4x8Tb and an SSD cache. The active machine will also have an NVMe in bare metal passthrough for the VMs.
  14. Thanks. Since the drives are now likely to be sold rather than passed on to family (dad didn't want them), I will zero them using the middle part of the preclear tool.
  15. Having just upgraded my array to use fewer but larger drives, I am left with a stack of smaller, older ones. Since these drives have no business or confidential information on them, what steps would you take to prepare them for selling or passing to a family member? Do I simply format? Should I zero? They are all currently sitting on the array in my Unassigned Devices group.
  16. It is just really just the preclear that I was needing to know about. I agree that the first parity build is the critical one and that is running now while I wait for the warranty replacement drive to arrive. Once that parity is completed at least I know I can let the array start and I can do the preclear of the drives I need. Thanks.
  17. Can I perform other tasks on an array such as running Mover or building Parity while new disks are going through the preclear script? The situation is that my array healthy but is currently stopped. I have three out of four new 8Tb disks coming to the end of their preclear (using the preclear plugin) but I now have even more disks that will need to be precleared (shortly to be followed by the warranty replacement for the one failed disk). I would like to remove some small but empty drives, incorporate the first three successfully cleared disks into the array, start the array and rebuild parity but also want to have the next batch of disks running through the preclear. Can I do this all at the same time?
  18. On the subject of VMs and GPU passthrough... I have seen the suggestions that you enable the iGPU (if your CPU has one) for unRAID's use and leave the main PCI GPU free for your VMs but what do you do in the use case where your CPU (say a Xeon) has no iGPU? I presume you would have a quick look at the PassMark performance of a typical iGPU of the current generation and pick up a lightweight PCI GPU for unRAID, yes? Would general "browsing and YouTube" VMs need their own light GPU too or can they make use of the emulated version of the one unRAID had access to? I mean this situation... say the board has GPU1 (lightweight) and GPU2 (gaming). Say you have unRAID for NAS and Plex Docker (to a viewer on the network), VM1 for browsing/Youtube and VM2 for Win10 gaming. Can VM1 make use of GPU1 or does it need its own discrete card?
  19. The same drive failed the preclear in only 15 minutes and gave a yellow SMART warning on the Dashboard. It is going back.

  20. I have just received four new WD 8Tb Reds from Scan.co.uk in the UK and run the Quick SMART Test on them while they are unassigned devices. This is their first power up since they were all removed from sealed packaging. While three are totally perfect with zero hours and only one spin up, the fourth drive has an extremely high Spin Retry Count as shown in the SMART report below. Is it even worth me preclearing this drive? Since it is brand new, should I return it immediately or is it possible that the SMART report itself is in error rather than the drive? WDC_WD80EFZX-68UW8N0_VK1DYR5Y-20170905-1235.txt EDIT : The issue is solved. Powering down the array and bringing it up again has cleared and correctly displayed the SMART report, both on-screen and in the text file. See the second SMART report for the same drive a few minutes later... Is this an unRAID GUI defect I need to report or is something else at play here? WDC_WD80EFZX-68UW8N0_VK1DYR5Y-20170905-1305.txt
  21. That is good to know. I just checked the other 840PRO I bought at the same time and which has been used for Win10 gaming and it has the Wear levelling Count at 96% so that is the one which is showing more use. Five times the amount of data written too. I think I will retire the Windows one and keep the drive I showed above as an addition to the cache pool on the backup server so it can digest bigger backups at a time before filling its cache.
  22. I have had a Samsung 840PRO 256Gb since 2013 and while it still passes a SMART check, the Wear Levelling Count has left zero at last. I know these SSDs have an overprovision but how concerned should I be about the health of this SSD? In summary, we have 3240 hours, 14667 power cycles, 34 reallocated sectors, 150 Power Recoveries and 8879245966 LBAs written. Samsung_SSD_840_PRO_Series_S12RNEAD213826E-20170904-1458.txt
  23. Cheers. They should arrive tomorrow along with cables, cache ssds, fans and a new UPS. I've been shopping!
  24. Fantastic, thanks. Just what I wanted to hear. Next question... do you think an Intel i3 3.6GHz and 16Gb of RAM can do all four at once or should I do them in pairs?
  25. I am about to set up my second unRAID box with 4x 8TB WD Reds and would like to know if I can preclear the new drives on the old array then move them to the new array once the preclear is complete? The old array is accessible, only in light use and has spare SATA ports. The new array is being changed from my main dual boot Linux/Win10 PC to unRAID with VMs and storage. While I have the SATA ports free, I don't want to tie up the new machine for the couple of days that the preclear will probably take as it is in frequent use.
