Nextcloud reports "disk space is low" when uploading large files, even though there is plenty of free space on the TrueNAS server and the Nextcloud user quota.

Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud App version: 30.0.0
Nextcloud Chart version: 2.0.17
Operating system and version : TrueNAS-SCALE-24.04.2.2
Apache or nginx version : Nginx (version not readily available in TrueNAS interface)
PHP version : (PHP version used by Nextcloud container not readily available in TrueNAS interface)

The issue you are facing:
I have 3TB of free space remaining (out of 4TB total) on my hard drive. However, when I try to synchronize files via the Nextcloud desktop app on Windows, I’m unable to transfer a file named MyVM.vdi (approximately 50GB in size). I get the error: “Disk space is low: Downloads that would reduce free space below 238 MB were skipped.”

Strangely, I was able to successfully upload around 100 videos totaling 80GB. I still have plenty of space left on my user quota: “374GB/1TB”. Additionally, my laptop, where the Nextcloud desktop app is installed, has approximately 30GB of free space.

Here are the different configuration points, with their values ​​defined from the truenas interface:

  • Max Upload Size (Giga Bytes) = 100
  • Max Execution Time (Seconds) = 120
  • PHP Memory Limit (Mega Bytes) = 256
  • Opcache Memory Consumption (Mega Bytes) = 512
  • Nginx Conf : Proxy timeouts (Seconds) = 60
  • Command : ffmpeg

Key points:

  • Ample HDD storage: 3TB free on TrueNAS Scale (4TB total)
  • User quota: 374GB used out of 1TB
  • Successful smaller uploads: Recently uploaded 80GB of videos without issue
  • Laptop free space: Approximately 30GB available
  • Laptop OS : Windows 11 23H2
  • Nextcloud desktop client : 3.14.1

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Attempt to upload a file larger than 50GB via the Nextcloud desktop app.
  2. Observe the “Disk space is low” error message.

There are some errors regarding your setup.
Some files have not passed the integrity check. List of invalid files… Rescan… For more details see the documentation ↗.
Could not check that the data directory is protected. Please check manually that your server does not allow access to the data directory. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its `trusted_domains` or the `overwrite.cli.url`. This failure may be the result of a server-side DNS mismatch or outbound firewall rule.
This server has no working internet connection: Multiple endpoints could not be reached. This means that some of the features like mounting external storage, notifications about updates or installation of third-party apps will not work. Accessing files remotely and sending of notification emails might not work, either. Establish a connection from this server to the internet to enjoy all features.
Your webserver is not set up to serve `.js.map` files. Without these files, JavaScript Source Maps won't function properly, making it more challenging to troubleshoot and debug any issues that may arise.
Unable to run check for JavaScript support. Please remedy or confirm manually if your webserver serves `.mjs` files using the JavaScript MIME type. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its `trusted_domains` or the `overwrite.cli.url`. This failure may be the result of a server-side DNS mismatch or outbound firewall rule.
Could not check if your web server properly resolves the OCM and OCS provider URLs. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its `trusted_domains` or the `overwrite.cli.url`. This failure may be the result of a server-side DNS mismatch or outbound firewall rule.

Server has no maintenance window start time configured. This means resource intensive daily background jobs will also be executed during your main usage time. We recommend to set it to a time of low usage, so users are less impacted by the load caused from these heavy tasks. For more details see the documentation ↗.
One or more mimetype migrations are available. Occasionally new mimetypes are added to better handle certain file types. Migrating the mimetypes take a long time on larger instances so this is not done automatically during upgrades. Use the command `occ maintenance:repair --include-expensive` to perform the migrations.
Detected some missing optional indices. Occasionally new indices are added (by Nextcloud or installed applications) to improve database performance. Adding indices can sometimes take awhile and temporarily hurt performance so this is not done automatically during upgrades. Once the indices are added, queries to those tables should be faster. Use the command `occ db:add-missing-indices` to add them. Missing indices: "dav_shares_resourceid_type" in table "dav_shares", "dav_shares_resourceid_access" in table "dav_shares", "fs_storage_path_prefix" in table "filecache", "fs_name_hash" in table "filecache", "schedulobj_lastmodified_idx" in table "schedulingobjects", "systag_by_objectid" in table "systemtag_object_mapping". For more details see the documentation ↗.
Could not check that your web server is properly set up to allow file synchronization over WebDAV. Please check manually. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its `trusted_domains` or the `overwrite.cli.url`. This failure may be the result of a server-side DNS mismatch or outbound firewall rule. For more details see the documentation ↗.
Could not check that your web server serves `.well-known` correctly. Please check manually. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its `trusted_domains` or the `overwrite.cli.url`. This failure may be the result of a server-side DNS mismatch or outbound firewall rule. For more details see the documentation ↗.
Could not check for WOFF2 loading support. Please check manually if your webserver serves `.woff2` files. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its `trusted_domains` or the `overwrite.cli.url`. This failure may be the result of a server-side DNS mismatch or outbound firewall rule. For more details see the documentation ↗.
Could not check that your web server serves security headers correctly. Please check manually. For more details see the documentation ↗.
Your installation has no default phone region set. This is required to validate phone numbers in the profile settings without a country code. To allow numbers without a country code, please add "default_phone_region" with the respective ISO 3166-1 code of the region to your config file. For more details see the documentation ↗.
