Bug description
Copying folders with files and subfolders when object storage as primary storage is configured is unreliable and very slow.
Installation details:
helm chart nextcloud-3.5.21
image: tag: 26.0.5-apache
db: mariadb
redis: enabled
Object Storage as primary storage: MinIO
Configured according to the following documentation: https://docs.nextcloud.com/server/13/admin_manual/configuration_files/primary_storage.html#simple-storage-service-s3
Steps to reproduce
- Create a folder with a subfolder. The folder should be around 600 MB. Create 10 files in the folder, 10 files in the subfolder. Some of the files should be around 100 MB, others only 2 MB
- Copy the folder via API (https://docs.nextcloud.com/server/19/developer_manual/client_apis/WebDAV/basic.html#copying-files-and-folders-rfc4918) or via Nextcloud UI.
- Depending on the
overwriteflag the following responses are returned:- overwrite
true: 423 Locked, Exception: OCA\DAV\Connector\Sabre\Exception\FileLocked, message: "xxx" is locked, existing lock on file: exclusive - overwrite
false: 412 Precondition Failed, Exception: Sabre\DAV\Exception\PreconditionFailed, message: The destination node already exists, and the overwrite header is set to false
- overwrite
- In > 90% of the requests the folder is not copied completely. Some files are not copied at all, others have the ending
.partand are incomplete. - The requests take > 60s
Expected behavior
The COPY command should function reliable. What also is remarkable is the overall latency of the UI and the COPY command. The UI is nearly unusable due to latency issues (showing folders and files in the overview, copying them, ...). For example the COPY command takes > 60s. On a similar installation without object storage as primary storage the requests take < 5s and work reliable. Also the overall latency of the UI is much better.
