Storage -> File Systems : infinite loading issue

  • Clean system:
    Storage -> File Systems -> it show list of filesystems, as expected

    How to reproduce the issue:
    1) install ZFS plugin via OMV-Extras
    2) open ZFS admin section
    3) click Import pool, type the correct name of the pool; the pool is found and mounted (I can see files with SSH)

    issue 1: I can no longer open Storage -> File Systems section (no error, just infinite loading)
    issue 2: I can no longer open Storage -> ZFS section ("Invalid RPC response. Please check the syslog for more information.")

    any ideas?

    Thanks in advance!

  • Syslog was completely empty. I tried it again and there is now an error message in it:

    Feb 7 15:57:00 server omv-engined[11697]: PHP Fatal error: Interface 'OMV\System\Filesystem\IFilesystem' not found in /usr/share/php/openmediavault/system/filesystem/ on line 5

    That file looks like this:

  • That means that after upgrade to OMV4, I need to uninstall OMV-Extras and download a different version for OMV 4.x.


    1) uninstall openmediavault-zfs 3.x plugin
    2) uninstall openmediavault-omvextrasorg 3.x
    3) install openmediavault-omvextrasorg 4.x
    3) install openmediavault-zfs 4.x plugin
    4) Storage - ZFS - import all pools

    Working again.

    Thanks Volker!
