VM Losing Access to physical drives while running RRS feed

  • Question

  • I have a hyper-v based vm that I use as a media server. It is connected to 5 physical hard drives that it serves data from. After it is left running for some time the OS on the VM (Ubuntu server 18.04.1 LTS) starts giving IO Errors on all the drives. When I check in hyper-v settings all of the physical hard drives show up as drive not found. shutting down the vm and re-selecting each of the drives from the drop down fixes the problem temporarily. This has been happening with increased frequency with the VM sometimes lasting less than a few hours before the problem arises.

  • What version of Hyper-V?  Is the host system a supported system for the version of the host operating system? (www.windowsservercatalog.com)  Are you running the vendor recommended drivers/firmware/etc. for the version of the operating system?

  • Windows 10 Pro version 1809, Hyper-V manager version 10.0.17763.1. All the drivers and firmware are up to date. The issue has been present for over a year through multiple windows updates.

  • This forum is for questions on Windows/Hyper-V server.  Your question is about Hyper-V on Windows 10.  That forum is located at https://social.technet.microsoft.com/Forums/en-US/home?forum=win10itprovirt

    Though the Hyper-V engine is the same on all platforms, the implementation varies from client to server.  In order to reach the experts on the Windows 10 implementation, you would be better served to ask the experts in the above reference forum.

  • Hi

     

    Good day!

     

    Here is a list of reasons that may cause this error on your external hard drive or other storage devices not initialized with I/O device error:

    ·         Virus attack,

    ·         Corrupted Master Boot Record,

    ·         Partition Loss,

    ·         Bad sectors on hard drive,

    ·         File system corruption.

    when any one of the above situations occurs, your hard drive or external hard drive would all become not initialized or unknown with I/O device errors.

    Could you give a more specific description on your issue? Please include but not limited to the following information

    >> It is connected to 5 physical hard drives that it serves data from.

    What kind of way that you used to connect to physical hard drives?

     

    >>After it is left running for some time the OS on the VM (Ubuntu server 18.04.1 LTS) starts giving IO Errors on all the drives.

    Could you provide the error in detail?

     

    >> When I check in hyper-v settings all of the physical hard drives show up as drive not found.

    Could you provide the screenshot for the Hyper-V setting?

     

    Best Regards,
