GeeseFS

Last update: May 10 2026

GeeseFS is a program with which you can mount a bucket on a device or server and work with it like a normal folder.GeeseFS is suitable for working with a large number of objects, up to 1 MB each.With GeeseFS you can work on Linux, Windows and macOS.

Customize GeeseFS

1. Configure access to S3.
2. Install the client.
3. Create a configuration.

1. Set up access to S3

Access can be configured by the Account Owner or a user with the role of iam.admin.

1. Create a service user with a role with access to S3.If you use a service user with the role of s3.user, object_storage_user or s3.bucket.user, an access policy must be configured in the bucket and its rules must allow access to this user.
2. Issue an S3 key to the user.

2. Install the client

Linux

1. Make sure that the FUSE utilities are installed by default:

   apt list --installed | grep fuse

2. If the utilities are not installed, install them:

   sudo apt-get install fuse

3. Download and install GeeseFS:

   wget https://github.com/yandex-cloud/geesefs/releases/latest/download/geesefs-linux-amd64
   chmod a+x geesefs-linux-amd64
   sudo cp geesefs-linux-amd64 /usr/bin/geesefs

Windows

1. If you do not have WinFSP installed, download and install it.

2. Download the geesefs-win-x64.exe file, but do not install it.

3. Optional: rename the file to geesefs.exe for convenience.

4. Create a geesefs folder.

5. Move the geesefs.exe file to the geesefs folder.

6. Add the geesefs folder to the PATH variable:

   6.1 In a Windows search, type Change System Environment Variables.

   6.2 Click Environment Variables.

   6.3. Select the PATH parameter.

   6.4. Click Edit → New.

   6.5 Add the folder path to the list.

   6.6. Press OK → OK.

7. For the variable environment settings to be applied, reboot the device.

Mount the bucket

One-time mounting

Linux

1. Create a folder to mount:

   mkdir /mnt/<folder_name>

   Specify <folder_name> - the name of the folder to which the bucket will be mounted.

2. Mount the bucket:

   sudo geesefs
   --endpoint https://<s3_domain>
   --region <pool>
   --profile <profile_name>
   <bucket_name> /mnt/<folder_name>

   Specify:

   • <s3_domain> - S3 API domain depending on the pool in which the bucket is located;
   • <pool> - pool where the buckets are located;
   • <bucket_name> - name of the bucket to be mounted;
   • <profile_name> - profile name, default default;
   • <folder_name> - name of the folder you created in step 1.

3. Make sure the buckets are mounted:

   df -hT /mnt/<folder_name>

   Specify <folder_name> is the name of the folder you created in step 1.

Windows

1. Open PowerShell.

2. Mount the bucket:

   geesefs --endpoint <s3_domain> --region <pool>
   <bucket_name> <destination>

   Specify:

   • <s3_domain> - S3 API domain depending on the pool in which the bucket is located;

   • <pool> - pool where the buckets are located;

   • <bucket_name> - name of the bucket to be mounted;

   • <destination> - the name of the new disk or the path to the folder in Windows where the bucket will be mounted. To mount the bucket:

     • as a disk - use a value like S:;
     • as a folder - use the path to the folder in quotes, e.g. "C:\Data\GeeseFS".

macOS

Once mounted, the folder will be mounted in Finder as an external disk.

1. Open the Finder or Terminal.

2. Create a folder to mount:

   mkdir -p "<local_folder>"

   Specify <local_folder> - the path to the folder.

3. Copy and save the path to the folder.

4. Mount the bucket:

   geesefs -o volname="<volume_name>"

Repair the tank

The method of unmounting depends on how the bucket was mounted - one-time or automatically.

One-time mounting

Linux

Unmount the bucket:

sudo umount /mnt/<local_folder>

Specify <local_folder> - the path to the folder to which the bucket is mounted.

Windows

1. Open PowerShell.

2. Press Ctrl + C.

3. Make sure the response appears on the command line:

   main.INFO Flushing all changes
   main.INFO Successfully exiting

macOS

1. Open Terminal.

2. Unmount the bucket:

   umount "<local_folder>" 2>/dev/null || diskutil unmount force "<local_folder>"

   Specify <local_folder> - the path to the folder to which the bucket is mounted.

Automatic mounting

Linux

1. Check the mount list:

   systemctl list-units --type=mount

2. In the row of the desired mount, copy the value of the UNIT column.

3. Disable automatic mounting:

   sudo systemctl disable mnt-<folder_name>.mount

   Specify <folder_name> - the name of the folder to which the bucket was mounted.

4. Make sure the buckets are unmounted:

   df -hT

Windows

1. Open PowerShell.

2. Uninstall the service with auto-mounted bucket:

   schtasks /Delete /TN "<task_name>" /F

   Specify <task_name> is the name of the task in the Windows service that starts the mount bucket at system startup.

3. Reboot the device.

4. Make sure that the buckets are no longer automatically mounted.

macOS

1. Open Terminal.

2. Check the mount point:

   mount | grep geesefs

3. Copy the address of the mount point.

4. Forcibly unmount the bucket:

   diskutil unmount force "<folder_path>"

   Specify <folder_path> - the path to the folder.

5. Stop the mount agent and delete the configuration:

   launchctl bootout gui/$(id -u) "$HOME/Library/LaunchAgents/<agent_name>.plist"
   rm "$HOME/Library/LaunchAgents/<agent_name>.plist"

   Specify <agent_name> - the name of the autorun agent file.

6. Make sure that the mounted bucket does not show up as a disk in Finder.
