How to move a partition in GNU/Linux?

How to move a partition to the beginning of the disk a bit? Parted wants a filesystem for some reason (I don't know why), I want just to shift all sectors left...

  • Are you using the partitions without FS? You can just set the FS to anyone with fdisk and then move them.

  • Thus is actually a LUKS container. But I don't think a partition mover should ever look inside the filesystem.

sfdisk, which intents to be a scriptable fdisk, has since some version the --move-data option. Example from their man page:



echo '+100M,' | sfdisk --move-data /dev/sdc -N 1

    Manual way with dd and fdisk:



    # fdisk -l /dev/sdb | grep sdb3
    /dev/sdb3 73402368 1953525167 940061400 83 Linux

    # fdisk /dev/sdb
    Command (m for help): d
    Partition number (1-4): 3
    Command (m for help): n

    Last sector, +sectors or +size{K,M,G} (73385984-1953525167, default 1953525167):
    Using default value 1953525167
    Command (m for help): w
    The partition table has been altered!

    # fdisk -l /dev/sdb | grep sdb3
    /dev/sdb3 73385984 1953525167 940069592 83 Linux

    # dd conv=notrunc bs=512 iflag=fullblock if=/dev/sdb3 count=100 skip=$((73402368-73385984)) seek=0 2> /dev/null | file -s -

    Now waiting for about 2h. (more looks more like 18h...)



    Note: this only moves data back, not forward.



    Pausing:



    # pidof dd
    907
    # kill -STOP 907
    # cat /proc/907/fdinfo/1
    pos: 586921398272
    flags: 0100001

    # kill -9 907

    remember 586921398272/512 = 1146330856


    Resuming:



    dd conv=notrunc bs=512 iflag=fullblock if=/dev/sdb3  skip=$((1146330856+73402368-73385984)) seek=1146330856 of=/dev/sdb3

      why not dd conv=notrunc bs=512 iflag=fullblock if=/dev/sdb skip=73402368 seek=0 of=/dev/sdb3 ? this way it, should work even f start of old sdb3 in not inside new sdb3

      A larger bs didn't help me on its own, however bs=1M iflag=direct oflag=direct did. Went from 40 MB/s to 400 MB/s on my SSD. Also, use status=progress

    You can always use dd.




    • Boot from a liveCD (or any other way which makes sure the partition is not mounted)


    • dd if=/dev/sdc2 of=somefile bs=1M to create a copy of the partition on a file.

    • fdisk (or whatever you like) to delete the partition

    • fdisk (or whatever you like) to create the partition in your desired place.


    • dd of=/dev/sdc2 if=somefile bs=1M to restore the contents from file.

    • Might be able tom but test it first. Esp. if you have no backup of the data on the partition. (Also note that if you do have a backup then there are way simpler solutions).

            You can always use dd.




            • Boot from a liveCD (or any other way which makes sure the partition is not mounted)


            • dd if=/dev/sdc2 of=somefile bs=1M to create a copy of the partition on a file.

            • fdisk (or whatever you like) to delete the partition

            • fdisk (or whatever you like) to create the partition in your desired place.
