Original GitHub issue: https://github.com/Mintplex-Labs/anything-llm/issues/3877

How are you running AnythingLLM?

Docker (local)

What happened?

When tried to embed and save any file to the workspace:

addDocumentToNamespace lance error: LanceError(IO): Generic LocalFileSystem error: Unable to copy file from /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest-f1f9a61a-bd25-4b7e-ab0e-558da26181e4 to /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest: Operation not supported (os error 95), /home/build_user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/lance-table-0.22.0/src/io/commit.rs:888:54 Caused by: LanceError(IO): Generic LocalFileSystem error: Unable to copy file from /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest-f1f9a61a-bd25-4b7e-ab0e-558da26181e4 to /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest: Operation not supported (os error 95), /home/build_user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/lance-table-0.22.0/src/io/commit.rs:888:54 Caused by: Generic LocalFileSystem error: Unable to copy file from /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest-f1f9a61a-bd25-4b7e-ab0e-558da26181e4 to /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest: Operation not supported (os error 95) Caused by: Unable to copy file from /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest-f1f9a61a-bd25-4b7e-ab0e-558da26181e4 to /app/server/storage/lancedb/finlaz.lance/_versions/1.manifest: Operation not supported (os error 95) Caused by: Operation not supported (os error 95)

Are there known steps to reproduce?

1- Run docker image using the following command to install storage location to an external SSD, example:

export STORAGE_LOCATION=/Volumes/YourExternalDriveHere/anythingllm &&
mkdir -p $STORAGE_LOCATION &&
touch "$STORAGE_LOCATION/.env" &&
docker run -d --restart=always -p 3001:3001
--cap-add SYS_ADMIN
-v ${STORAGE_LOCATION}:/app/server/storage
-v ${STORAGE_LOCATION}/.env:/app/server/.env
-e STORAGE_DIR="/app/server/storage"
--name anythingllm
mintplexlabs/anythingllm

2- Attach and save any file to the workspace.

This has been reported before, and it is out of scope for AnythingLLM That being said, the technical reason is exactly as reported - the filesystem on the external disk blocks the copy op typically solved by permission changes on the directory you are using

I resolved the issue by reformatting the external drive to APFS. It was previously formatted as exFAT, which is known to have problems with hard links.

Thanks again!
