Clone OMV 4.X from larger USB drive to smaller USB drive

1. offizieller Beitrag

    Hello,


    I am trying to clone 64 GB USB flash drive with OMV 4.x to 16 GB USB flash drive. I tried clonezilla in expert mode and Acronis, but all unsuccessful. I found this thread, but got stuck on tune2fs line giving me invalid UUID format error.
    My original drive is sda and drive where I like to clone to is sdb. Here is an example of fdisk:


    root@sysresccd / % fdisk -l

    Disk /dev/loop0: 469.9 MiB, 492683264 bytes, 962272 sectors
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes




    Disk /dev/sda: 59 GiB, 63350767616 bytes, 123731968 sectors
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes

    /dev/sdb2: UUID="5cfcf1af-c0fb-4342-bddc-85aeecdb8383" TYPE="swap" PARTUUID="e9c3d89e-02"
    root@sysresccd / % tune2fs /dev/sdb1 -U uuid_from_sda1_from_blkid
    tune2fs 1.43.6 (29-Aug-2017)
    Setting UUID on a checksummed filesystem could take some time.
    Proceed anyway (or wait 5 seconds to proceed) ? (y,N) <proceeding>
    tune2fs: Invalid UUID format

    I would appreciate the solution to solve my problem.

    Assuming that the partitions on the larger drive do not exceed the total size of the smaller drive; take a look at this -> post. (If you didn't expanded the default partitions when OMV was installed, you should be fine.)


    In the cloning operation; when reading the larger drive with Win32diskimager, remember to check the box; "Read Only Allocated Partitions".

    I tried clonezilla in expert mode and Acronis, but all unsuccessful.

    Have you enabled the -icds switch in clonezille to skip checking the destination disk size?


    Edit: just noticed it is already mentioned in the other thread
