environment:
- OOD 4.0.8 unpopulated dev system
- hyper-v VM
- selinux disabled
- cgroupsv2 enabled
- no upload-limit mods in /etc/ood/config/apps/dashboard/env
I’m seeing an issue that seems very similar to [this March 2024 report](https://discourse.openondemand.org/t/large-uploads-failing-ood-3-0-1/3315) about large uploads failing with OOD 3.0.1.
However my “large” uploads are only ~1.5GB, and the problem seems isolated to uploading to our /scratch fs (which is an NFS export of a bare metal lustre mount to our Vast system).
About the error:
- filemanager’s upload dialog eventually says “Upload failed” after sitting at 100% for a long time
- the browser’s console shows 4x POST errors suggesting it tried 4 attempts (probably why it sat at 100%)
- the uploaded does seem to always be _successfully_ uploaded, despite the failure claim, as verified in a shell with md5sum
- a 1572605045 byte file seems to always generate this failure
- a 1474317229 byte file seems to _sometimes fail_ completely, _but sometimes succeed_ (meaning the filemanager sometimes says “Upload failed” and the browser’s console shows 4 POST errors… but other times the browser’s console will show fewer than 4 POST errors, and the filemanager will act as though no error occurred)
- uploading to our /home fs does not fail
(I don’t know how relevant it is but [this Jan 2025 report](https://discourse.openondemand.org/t/set-file-upload-to-inherit-permission-of-parent-directory/3819/5) also mentions a similar quasi-failure-quasi-success mechanic related to a lustre fs.)
The nginx/PUN’s log doesn’t seem to show any errors, but Apache indicates it’s timing out, and not much more.

We’ve had a couple of reports come through about this lately as well, but with files ~2.5GB, and seem to fail no matter where they’re uploaded in our storage
