partx: /dev/sdd: error adding partition 1

  • 772

I'm wanting to add a Swap partition to a CentOS 7 machine (running in VirtualBox). However, when I try and add it I get this error:

partx -a /dev/sdd1
partx: /dev/sdd: error adding partition 1

Here's the output of fdisk /dev/sdd

Command (m for help): p

Disk /dev/sdd: 8589 MB, 8589934592 bytes, 16777216 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 label type: dos
Disk identifier: 0x1b359154

/dev/sdd1            2048     4196351     2097152   83  Linux

Any suggestions?

  1. Try to load the nbd module with max_part parameter:

    modprobe nbd max_part=16

    It fixed this issue for me.
