Messed up HDD upgrade

  • I bought two 4 TB HDDs to replace my 5 TB external hard drive (of which only 3 TB was used). I thought the best way to transfer over the data was to clone the disk using dd. Now, however, everything has gone wrong and I can no longer excess, nor remove either of the new or old drives. blkid gives a hint about the problem, but I don't know how to fix it.

    Code
    root@CerpacNAS:/srv# blkid
    /dev/sdc1: LABEL="Backup" UUID="3c216b51-0d7b-414c-a860-a2f62898174b" TYPE="ext4" PARTUUID="455b4be9-fb7c-4ac5-ade2-634cba8d647a"
    /dev/sdb1: LABEL="MediaInternal" UUID="ac71b6fb-516d-469c-bb86-3f065030bb68" TYPE="ext4"
    /dev/sda1: UUID="04d61ad6-45c6-4d9e-b6e7-eab0fcea3acf" TYPE="ext4" PARTUUID="9976099b-01"
    /dev/sda5: UUID="010109e8-70cc-461b-9bc9-dcc08316ef9e" TYPE="swap" PARTUUID="9976099b-05"
    /dev/sdd1: LABEL="Media" UUID="e92a6b8f-0dae-40d7-9805-b5b38985f161" TYPE="ext4" PARTUUID="2c28ae74-e280-45d1-b19e-e68897b656ba"
    /dev/sde1: LABEL="Media" UUID="e92a6b8f-0dae-40d7-9805-b5b38985f161" TYPE="ext4" PARTUUID="5022ebbc-697e-4a54-905f-a6ebca12f4c7"
    /dev/sdf1: PARTUUID="7eae4410-b55e-4441-86ae-d57668ee9a82"

    sdd is the old external drive, and sde and sdf the two new ones. Thanks for the help.

  • When I try to mount the drive, this error appears. And I don't seem able to unmount the old drive because it has the same UUID.

    And how did you copy one drive on two new drives using dd?

    Change the UUID of the new one.

    I only cloned it to one of the new drives with dd.

    And where is sdf1 coming from? I understood it is the second new drive.


    I would wipe the two new drives. Add them to OMV and create filesystems on them and mount them.

    Then rsync the data from the old drive to one of the new ones. From CLI or with a scheduled job from the GUI
