No filesystem backend exists for type 'cifs' errors - but all seems to work anyway

  • I get the error below when I visit a couple of services.


    I guess there is some settings thats got lost during the last week, when I have had problems during the upgrade.


    This time it came when I opened the nginx service in the GUI. But I get this from other as well.


    Code
    No filesystem backend exists for type 'cifs'.
    Error #0:
    OMV\AssertException: No filesystem backend exists for type 'cifs'. in /usr/share/php/openmediavault/system/filesystem/backend/manager.inc:103
    Stack trace:
    #0 /usr/share/openmediavault/engined/rpc/sharemgmt.inc(147): OMV\System\Filesystem\Backend\Manager->assertBackendExistsByType('cifs')

    #4 /usr/sbin/omv-engined(536): OMV\Rpc\Rpc::call('ShareMgmt', 'enumerateShared...', Array, Array, 1)
    #5 {main}
  • The system do work but I cant really change things as this exception prevents pages to load properly, Like "File Systems".


    I can see that there are items /etc/openmediavault/config.xml under fstab that is missing from /etc/fstab.


    But as I accidentaly removed OMV and succeeded to reinstate it, I had presumed it to be the other way around. That things would be gone from omv setting but in place for fstab...


    For instance this section is from config.xml but no UUID starts with "fd9" is fstab.


    Code
    <mntent>
            <uuid>fd900769-c5d8-447d-b1c1-d803216edaa0</uuid>
            <fsname>c95301c0-9790-48c6-ab1f-17da8e3c3538</fsname>
            <dir>/media/c95301c0-9790-48c6-ab1f-17da8e3c3538</dir>
            <type>cifs</type>
            <opts></opts>
            <freq>0</freq>
            <passno>0</passno>
            <hidden>1</hidden>
          </mntent>



    What steps should I do to realign my system so that everything works as expected again?
    Any specific config files I can add that would help the troubleshooting or logs?


    On the File system page I get this exception:
    Error #0:exception 'OMV\Exception' with message 'No filesystem backend exists for 'cifs'.' in /usr/share/openmediavault/engined/rpc/filesystemmgmt.inc:390Stack trace:#0 [internal function]: OMVRpcServiceFileSystemMgmt->getList(Array, Array)#1 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)#2 /usr/share/php/openmediavault/rpc/rpc.inc(86): OMV\Rpc\ServiceAbstract->callMethod('getList', Array, Array)#3 /usr/sbin/omv-engined(536): OMV\Rpc\Rpc::call('FileSystemMgmt', 'getList', Array, Array, 1)#4 {main}

    Sounds like the remotemount plugin isn't installed or partially installed.

    omv 7.0-32 sandworm | 64 bit | 6.5 proxmox kernel

    Please try ctrl-shift-R and read this before posting a question.

    Please put your OMV system details in your signature.
    Please don't PM for support... Too many PMs!

  • Thanks. That was the clue I needed.


    I had not enabled omv-extras testing this time (planning on keeping it as basic as possible).
    But enabling that and installing the remoteMount plugin solved the issue.
