snf-image-creator qemu-nbd write lock issue

[Dimitris Maroulidis]

Hello,

I'm trying to use snf-image-creator and snf-mkimage to create an image
to upload to ~okeanos and I'm getting the following output.

RAN: '/usr/bin/qemu-nbd -c /dev/nbd0 -r
/home/dimitris/.snf_image_creator.RtsKLC/snapshot-c3bJRe'

STDOUT:


STDERR:
Failed to blk_new_open
'/home/dimitris/.snf_image_creator.RtsKLC/snapshot-c3bJRe': Failed to
get shared "write" lock
Is another process using the image?


I'm tried using an Ubuntu 18.04 server install on a qcow2 file, and the
official cloudimg as a raw img file from ubuntu.com as the input image
and the process is terminated during the md5 hash calculation. I'm
running the process on an Ubuntu 18.04 amd64 system with plenty of storage.

I've made sure that no one other than the executable is using the image
file by moving it to another location, and by running the command
immediately after I login to my PC, but to no avail.
