Singularity fails to build image on disk with sufficient space

[jhlegarreta]

Hi,
thanks for developing and maintaining this tool.

I am trying to build a singularity image following https://qsiprep.readthedocs.io/en/latest/installation.html#singularity-container:

singularity build /mnt/data/containers/qsiprep/qsiprep-0.19.0.sif docker://pennbbl/qsiprep:0.19.0

However, the build is systematically failing with the following error:

INFO:    Creating SIF file...
FATAL:   While performing build: while creating squashfs: create command failed: exit status 1: Write failed because No space left on device
FATAL ERROR: Failed to write to output filesystem

I have set my SINGULARITY_CACHEDIR to point to a hard drive that I have mounted and that has 4 TB of capacity. The variable reads

/mnt/data/containers/.singularity

The disk capacity reads

$ df -H
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           3.4G  2.5M  3.4G   1% /run
/dev/nvme0n1p2  135G  106G   22G  83% /
tmpfs            17G  318M   17G   2% /dev/shm
tmpfs           5.3M  4.1k  5.3M   1% /run/lock
/dev/nvme0n1p4  333G  183G  134G  58% /home
/dev/nvme0n1p1  1.1G  6.4M  1.1G   1% /boot/efi
/dev/sda1       4.0T  316G  3.5T   9% /mnt/data
tmpfs           3.4G  181k  3.4G   1% /run/user/1001

So the disk at issue has only 9% of its capacity used; the usage of the disk at issue reads

$ du -hs /mnt/data
295G	/mnt/data

Version of Singularity:

singularity-ce version 3.11.3

Expected behavior

I would expect the singularity image to be built without issues.

Actual behavior

The image build process fails apparently due to a disk space problem.

Steps to reproduce this behavior

Run

singularity build /mnt/data/containers/qsiprep/qsiprep-0.19.0.sif docker://pennbbl/qsiprep:0.19.0
