  1. I've been running Emby in a VM on Hyper-V for a couple of years now. Recently I've been trying to resolve some disk activity/latency issues that have been causing delays while loading and moving around in Emby from various clients. I think I've finally found my solution and wanted to share what I learned on the off chance it might help someone else. Long story short, move the cache/metadata/transcode-temp directory to a separate virtual hard disk (vhd). I noticed that when an Emby client would take a long time to load or start to timeout, disk activity on the server would jump noticeably. I also found that running the disk cleanup task would cause the same kind of usage. While monitoring the disk performance in task manager and resource monitor I would see that disk activity would max out, the disk queue length would be around .90 - 1.5 and average response time for the disk would hit 500ms. All this even though the disk throughput was only being reported at about 500kbps. I had two vhdx's on the VM, a Fixed size Disk for C: and another Fixed size disk for D: which is where shows are recorded. The first thing I did to try and improve the situation was reconfigure my Hyper-V's host storage as a Raid 10 array instead of Raid 5. This helped a little but not significantly and the issues were still present. I kept monitoring disk usage and noticed that the cache directory was being accessed rather frequently so I decided to move the Emby cache to a different disk. I added a third 10gb Fixed size disk and changed the cache path. This helped a little but I would still see performance issues when the Library.db was being accessed heavily. After looking into if I could move the Library.db to a different directory (and finding out it would be rather difficult) I noticed that the Metadata directory would show up frequently so I decided to move that instead. I moved the metadata location to the same drive as the cache and after refreshing the metadata in my libraries I finally noticed a significant improvement in performance. I also decided to move the transcoding-temp directory to the third drive as well just to cover all my bases. I originally did not think that moving the cache/metadata directories to a different virtual disk would make a difference since all the VHD's were on the same physical volume. But doing just that appears to have resolved my issue and now I regret not doing it sooner, I've been running performance tests since making the changes and so far I have not been able to re-produce my original performance issues with a variety of different clients including FireTV/Web/Theater. My Emby clients are much more responsive and not having to sit around and wait while browsing my music library is refreshing. And if I never see that VolleyError timeout message again I'll be very happy. I'm going to keep a close eye on my disk utilization and performance for the next few days but wanted to share what I was experiencing and what I did in case anyone else runs into the same issue. Also, on a side note, I did try enabling Quality of Service Management on the Virtual Disks but it ended up making the situation worse. I'm also not sure if this solution applies to only Hyper-V or also VMware. I'm not running VMware ESXi at home so I can't say for certain. But if you are running Emby in VMware and are having a similar issue then maybe this will help you as well.
  2. Hi All, What does the following indicate? 2019-08-15 17:29:22.135 Error App: Error resolving path \\dondersteendc\Media_DSdcTiered\TV Series\TV Series - Ended\Avatar The Last Airbender\Season 02 *** Error Report *** Version: 4.2.1.0 Command line: C:\Shares\Emby190814\system\EmbyServer.dll -service Operating system: Microsoft Windows NT 6.2.9200.0 64-Bit OS: True 64-Bit Process: True User Interactive: True Runtime: file:///C:/Shares/Emby190814/system/System.Private.CoreLib.dll Processor count: 8 Program data path: C:\Shares\Emby190814\programdata Application directory: C:\Shares\Emby190814\system System.IO.IOException: System.IO.IOException: An unexpected network error occurred : '\\dondersteendc\Media_DSdcTiered\TV Series\TV Series - Ended\Avatar The Last Airbender\Season 02' at System.IO.Enumeration.FileSystemEnumerator`1.GetData() at System.IO.Enumeration.FileSystemEnumerator`1.FindNextEntry() at System.IO.Enumeration.FileSystemEnumerator`1.MoveNext() at System.Linq.Enumerable.SelectEnumerableIterator`2.ToArray() at System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source) at MediaBrowser.Controller.Providers.DirectoryService.GetFileSystemEntries(String path) at MediaBrowser.Controller.IO.FileData.GetFilteredFileSystemEntries(IDirectoryService directoryService, String path, IFileSystem fileSystem, IServerApplicationHost appHost, ILogger logger, ItemResolveArgs args, Int32 flattenFolderDepth, Boolean resolveShortcuts) at Emby.Server.Implementations.Library.LibraryManager.ResolvePath(FileSystemMetadata fileInfo, IDirectoryService directoryService, IItemResolver[] resolvers, Folder parent, LibraryOptions libraryOptions) at Emby.Server.Implementations.Library.LibraryManager.ResolveFileList(List`1 fileList, IDirectoryService directoryService, Folder parent, IItemResolver[] resolvers, LibraryOptions libraryOptions) Source: System.IO.FileSystem TargetSite: Boolean GetData() I’m working on a VM with Emby and I'm currently in the testing phase. Most of it working well except that Emby seems to get stuck scanning a certain directory. As far as I can understand it must be folder permission related. Running the latest version What do you think? More info on request and thank for any help or suggestions, Peran embyserver.txt
  3. Does hardware acceleration with Hyper-V RemoteFX work? I have tried with the following setup, but it does not appear as an option: Setup: Emby version: 4.1.1.0 Host: Windows 10 1903 Enterprise VM: Windows 2019 Server Standard Graphics Cards: 1080ti and P2000
  4. Been using MB2 for a few years and looking to move to MB3. What do most recommend for the OS if you could pick from Win 7, 8 or Server 2012? I think I would like to maybe even run it has a Hyper-V, which would mean Win 8 or server 2012. That way I could take snapshots before changes and roll back if I didn't like the results. Also I could possibly do a P2V on my current Win 7 machine running MB2 and run them side by side until I get MB3 setup or figure out if I even want it over MB2. My setup if that helps at all is that I have my HTPC setup with my TV and stereo, so it would be the MB3 server and also need to be a client. Then I would like to use say an android tablet (not yet purchased) to remote control this setup with the output going to my TV. I browsed a thread already on that part so I think it can be done. Thanks
