Migration Minio to Local Storage

[clementthenard]

Hi,

I tried to migrate Minio to local storage in a self-host environnement. But I've an error when I try to download old files.

What I've done :

• Download bucket's data
• Move bucket's data on specific folder
• Change .env variables to use local storage

What works :

• Upload file / images
• Download new file / images uploaded

What doesn't work :

• Download old files / images uploaded before migration on local storage

When I click on a file to download it, this is what it returns to me :

• Client side :

• Server side :

0|outline  | [Error: EISDIR: illegal operation on a directory, read] {
0|outline  |   errno: -21,
0|outline  |   code: 'EISDIR',
0|outline  |   syscall: 'read'
0|outline  | }

Best regards,
Clément.

Interesting, you should check the key column in the database matches up to the path on disk. That's clearly not the case here for some reason

[clementthenard]

I don't understand because key column's value is uploads/8a3d1ea1-f43e-42c3-a686-b3919e018b83/0788e1ee-4de5-4b97-ab6c-bee8dca025e4/Font Awesome Pro.zip and FILE_STORAGE_LOCAL_ROOT_DIR value is /var/lib/outline/data.

Obviously file exists in the directory.

It could also be a permissions issue, those moved files having different permissions to newly uploaded ones

This is because you copied the MinIO bucket data directly to the local filesystem. You must use the mc cp utility (be sure to reference your MinIO bucket alias and not the local dirs) to copy the files otherwise Outline will attempt to access directories as if they are files -- hence the illegal operation on a directory error.

Shouldn't the documentation (quoted below) be updated to mention this?

This is particularly useful when migrating from previously using Minio, as you can point the app at where the files were previously stored and everything will continue to work.

This is a little misleading and is exactly what I did until I found this thread.

Happy to update the docs, are you able to articulate the steps that were needed? I haven't done the migration myself.
