failed to write (No space left on device) error in image creation via DIB

It is probably trying to build in a tmpfs? See https://docs.openstack.org/diskimage-builder/latest/user_guide/building_an_image.html#speedups

I suggest exporting DIB_NO_TMPFS=1 into the environment to stop this

This has been a point of confusion before. I'm wondering if we should turn this off by default

Used following in dib virtual env

sudo DIB_NO_TMPFS=1 ./disk-image-create -no-tmpfs -a ppc64el -o ubuntu-vm1 -t raw -x vm ubuntu --logfile diblogvm1.txt

Still running into same error of disk space.

Attaching log?field.comment=Used following in dib virtual env

sudo DIB_NO_TMPFS=1 ./disk-image-create -no-tmpfs -a ppc64el -o ubuntu-vm1 -t raw -x vm ubuntu --logfile diblogvm1.txt

Still running into same error of disk space.

At this point in the build its just running in a chroot so either the tmpfs disabling must not be working and you are running out of space there or you are actually running out of disk space on a fs.

Can you try running with check_break=after-error set as well? This should drop you in to a shell at the point of failure. If this works could you check / paste the output of 'df -h'.

 sudo DIB_NO_TMPFS=1 ./disk-image-create -a ppc64el -o ubuntu-vm1 -t raw -x --no-tmpfs vm ubuntu --logfile diblogvm2.txt

I see --no-tmpfs not to be working
It needs 547MB and 4GB RAM

check_break=after_error doesnt seem to work @greghaynes

--no-tmpfs doesnt work

I pointed my /tmp to a bigger volume space and continued
