multipath disks get device paths duplicated

  • Hi fellas,
    I'm using OMV 3.x distro as a VM, I provided some HDDs via iSCSI (I need volumes larger than 2TB each).
    Everything good via Debian 8.8: I performed manual setup via iscsiadm, multipath labels them correctly /dev/dm-x
    The problem with OMV is that duplicated the devices, even though they do have obviously the same Serial Number:




















    For that reason /dev/dm-x ought be supported.



    How to deal with that? Do you use OMV as a VM?
    Any advice? Thanks

  • I cannot use the /dev/dm-0 disk
    I had to create a New Filesystem via gui, on a blank iSCSI disk.
    The device selection is right, iSCSI disks are listed via Device mapper, excluded the already existing partition i created maually
    I have to sync files via terminal from dm-0 to dm-1
