Unmount LUKS not possible

    Hello all,

    I have a problem unmounting an (external) LUKS encrypted harddisk. I would like to remove the disk from my system.

    Current configuration: HP N54L running OMV 4.1.36-1

    Several internal HDs and 1 external HD connected via USB


    The external HD is LUKS encrypted and is currently mounted.

    -Filesystem unmount in OMV is greyed out

    -LUKS Plugin "Lock disk" is greyed out

    - 1 sharedfolder pointing to this HD cannot be deleted (Greyed out)


    How can I safely remove this disk?

    Quote from MarcS

    1 sharedfolder pointing to this HD cannot be deleted (Greyed out)

    Then this folder is probably used in a service (smb, nfs, scheduled job, ...)

    Remove it from that service.

    If you do not find the service, install the resetperms plugin which shows you which sharedfolder is used where.

    Thanks for the tips.

    I have no service linked to that drive.

    I also cannot find the restperms Plugin. When I press "Check" under Plugins I get the following error:

    For OMV4:

    The commands work up until:

    apt-key add omvextras2026.asc which results in error

    ..but the Plugin is now installing -> worked. Thanks!

    The issue was the fact that a disabled SMB share was pointing to the external HD.

    So it is not enough to disable an SMB share before unmounting the underlying drive, the share must be deleted.
