Mapping HPC drives with SSHFS

Besides mapping HPCC drives with SMB, SSHFS can also enable mounting of HPCC file systems on a local computer. Different from SMB mapping, which can only map to home or research space via the MSU campus network, this method can also work on your scratch space and uses any internet network.

Warning

You will need to generate an authentication key by following the direction of SSH Key-Based Authentication if you do not already have one set up.

Mac OSXLinuxWindows

Download and install (or upgrade) the most recent versions of the following packages: FUSE for macOS and SSHFS from https://osxfuse.github.io.
Reboot (required)

Using the Terminal, create a directory (as <local_mount_point> in step 4) for each filesystem you wish to mount. If you are creating the folder outside of your home directory, you may need to use sudo before each command (sudo = superuser do ) and may also need to open the access permission accordingly.

[MacBook-Pro:~ icer2]$ mkdir <local_mount_point>
/* begin example home directory */
[MacBook-Pro:~ icer2]$ mkdir /Users/icer2/hpcc_home
/* end example home directory */
/* begin example scratch directory in the Mac /Volumes folder where drives are mounted */
[MacBook-Pro:~ icer2]$ mkdir /Users/icer2/hpcc_scratch
/* end example scratch directory */

Mount the directory using the sshfs command. We suggest you add these additional flags to the command to make it be more "Mac-like" : -ocache=no , -onolocalcaches and -o volname=hpcc_home . For the last option, '-o volname' is the name that displays in the Finder title bar, so change it for difference file folders (e.g. use -o volname=hpcc_scratch for your scratch folder). After running the command, enter the password for logging into HPCC and the FUSE drive icon will show on the desktop of your local Mac computer.

[MacBook-Pro:~ icer2]$ sshfs <user_id>@rsync.hpcc.msu.edu:<remote_directory_to_mount> <local_mount_point> -ovolname=hpcc -o allow_other,defer_permissions,follow_symlinks,reconnect -ocache=no -onolocalcaches
/* begin example hpc's home directory, using /mnt/home/hpc/ */
[MacBook-Pro:~ icer2]$ sshfs hpc@rsync.hpcc.msu.edu:/mnt/home/hpc/ /Users/icer2/hpcc_home -o volname=hpcc_home -o allow_other,defer_permissions,follow_symlinks,reconnect -ocache=no -onolocalcaches
/* end example home directory */
/* begin example hpc's scratch directory with authorized key file ~/.ssh/id_rsa, using /mnt/gs18/scratch/users/hpc */
[MacBook-Pro:~ icer2]$ mkdir /Users/icer2/hpcc_scratch
[MacBook-Pro:~ icer2]$ sshfs hpc@rsync.hpcc.msu.edu:/mnt/gs18/scratch/users/hpc /Users/icer2/hpcc_scratch -o volname=hpcc_scratch -o allow_other,defer_permissions,follow_symlinks,reconnect,IdentityFile=~/.ssh/id_rsa -ocache=no -onolocalcaches
(No password input)
/* end example scratch directory */

If <remote_directory_to_mount> is a static link, please make sure

to put / at the end of the directory path:

-   For your home space, please use `/mnt/home/<user_id>/` instead  of
`/mnt/home/<user_id>`.
-   For your research space, please use `/mnt/research/<group_name>/`
instead of `/mnt/research/<group_name>`.

As the above example (starting from line 5), home space
`/mnt/home/hpc/` is used on line 7 instead of `/mnt/home/hpc`.

To unmount a filesystem, use the umount command.

Note

It's just the letter u before mount, NOT unmount.
```
    umount <local_mount_point>
    /* begin example */
    umount /Users/icer2/hpcc_home
    /* end example */
```
You'll see these folders in the finder if you use the Go menu, but you

won't see them listed in the left side with the other mounted drives. You must use the terminal and umount command to disconnect.
