# Attach or detach object store buckets using the CLI

This page describes how to attach or detach object store buckets to or from filesystems using the CLI.

Using the CLI, you can:

* [Attach an object store bucket to a filesystem](#attach-an-object-store-bucket)
* [Detach an object store bucket from a filesystem](#detach-an-object-store-bucket)

## **Attach an object store bucket** to a filesystem

**Command:** `weka fs tier s3 attach`

To attach an object store to a filesystem, use the following command:

`weka fs tier s3 attach <fs-name> <obs-name> [--mode mode]`

**Parameters**

<table><thead><tr><th>Name</th><th width="367.3333333333333">Value</th><th>Default</th></tr></thead><tbody><tr><td><code>fs-name</code>*</td><td>Name of the filesystem to attach with the object store.</td><td>​</td></tr><tr><td><code>obs-name</code>*</td><td>Name of the object store to attach.</td><td></td></tr><tr><td><code>mode</code></td><td><p>The operational mode for the object store bucket.<br>The possible values are:</p><ul><li><code>writable</code>: Local access for read/write operations.</li><li><code>remote</code>: Read-only access for remote object stores.</li></ul></td><td><code>writable</code></td></tr></tbody></table>

## **Detach an object store bucket** from a filesystem

**Command:** `weka fs tier s3 detach`

To detach an object store from a filesystem, use the following command:

`weka fs tier s3 detach <fs-name> <obs-name>`

**Parameters**

<table><thead><tr><th width="265">Name</th><th>Value</th></tr></thead><tbody><tr><td><code>fs-name</code>*</td><td>Name of the filesystem to be detached from the object store</td></tr><tr><td><code>obs-name</code>*</td><td>Name of the object store to be detached</td></tr></tbody></table>

To [recover from a snapshot](/5.1/weka-filesystems-and-object-stores/snap-to-obj.md#creating-a-filesystem-from-a-snapshot-using-the-cli) uploaded when two `local` object stores have been attached, use the `--additional-obs` parameter in the `weka fs download` command. The primary object store should be the one where the locator has been uploaded to

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.weka.io/5.1/weka-filesystems-and-object-stores/attaching-detaching-object-stores-to-from-filesystems/attaching-detaching-object-stores-to-from-filesystems-1.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
