datalad save on fmriprep freesurfer output fails for brainmask*.mgz files only

[lnnrtwttkhn]

What is the problem?

I created a new DataLad dataset on the freesurfer output of fMRIPrep.
A subsequent datalad save command was successful for all files except the brainmask.auto.mgz and brainmask.mgz files of all subjects (located in </freesurfer/sub-XX>/mri/).
The error message reads:

[ERROR  ] git-annex: sub-XX/mri/brainmask.mgz: rename: resource busy (Device or resource busy) [add(/path/to/freesurfer/sub-XX/mri/brainmask.mgz)]

What steps will reproduce the problem?

Unfortunately, I can't share my own data-set at this point but maybe this behavior could be reproduced with another fMRIPrep dataset's /freesurfer output? I used fMRIPrep version 1.2.2.

What version of DataLad are you using (run datalad --version)? On what operating system (consider running datalad wtf)?

datalad --version
datalad 0.13.0

operating system version (excerpt from datalad wtf):

## system
  - distribution: debian/9.12
  - encoding:
    - default: utf-8
    - filesystem: utf-8
    - locale.prefered: UTF-8
  - max_path_length: 275
  - name: Linux
  - release: 4.19.0-0.bpo.6-amd64
  - type: posix
  - version: #1 SMP Debian 4.19.67-2+deb10u2~bpo9+1 (2019-11-12)

BTW, when I run datalad wtf, I get this error but ouput is still produced:

Error initializing plugin EntryPoint(name='kwallet', value='keyrings.alt.kwallet', group='keyring.backends').
Traceback (most recent call last):

Is there anything else that would be useful to know in this context?

nothing particular comes to mind.

Have you had any success using DataLad before? (to assess your expertise/prior luck. We would welcome your testimonial additions to https://github.com/datalad/datalad/wiki/Testimonials as well)

yes, so far, DataLad has been working like a charm for me! It's a great tool, thanks!

I am using DataLad 0.13 and fMRIprep 20.1.1 -- I do not have this issue. Are you on an NFS partition? NFS is not a friendly fellow...

Thanks for your speedy reply @mih!

It's our cluster and I think it's BeeGFS storage.

Does that help? Thanks!
