Error creating a KVM pool

  • Hi,


    i'm using OMV since many Years and like it very much.


    At the Moment i want to test the KVM Plugin since the Upgrade to OMV6 there is an error which occurs.

    Allways when i try to create a Storage Pool in an Directory it shows this message:


    500 - Internal Server Error

    Failed to execute XPath query '//system/fstab/mntent[uuid='79684322-3eac-11ea-a974-63a080abab18']'.


    Non of my raids, mountpoints or shared folders has this uuid

    how can i remove this error/uuid?

    I should've looked at the uuid closer. That is the sharerootfs uuid. Are you only seeing this when clicking the folder button in the web interface? Try ctrl-shift-R. What is the output of: dpkg -l | grep openme

    everytime i push this button no matter if directory, share or anything else

    That function relies on a working sharerootfs plugin. What is the output of:

    I can now Add KVM Pools

    You could before too. You would just have to type in the path and not use the directory chooser.


    is there any configuration lost that i have to reconfigure?

    Nope. It only adds one entry to mntent. Did you edit the database? I can't figure out how that entry was deleted.
