====== Mounting with SSHFS ======

===== Create SSH Public Key =====

Create a public key on you workstation:

  aceadmin@ace-ws-17:~$ ssh-keygen
  Generating public/private rsa key pair.
  Enter file in which to save the key (/home/aceadmin/.ssh/id_rsa): 
  Enter passphrase (empty for no passphrase): 
  Enter same passphrase again: 
  Your identification has been saved in /home/aceadmin/.ssh/id_rsa.
  Your public key has been saved in /home/aceadmin/.ssh/id_rsa.pub.
  The key fingerprint is:
  6d:22:99:96:82:c4:7a:e9:53:47:d0:78:24:d7:67:be aceadmin@ace-ws-17
  The key's randomart image is:
  +--[ RSA 2048]----+
  |    o+o.         |
  | .  .+o . o      |
  |  o  ..  +       |
  | o o . + ..      |
  |. + o B S o.     |
  | o . + . oE      |
  |  o              |
  |   .             |
  |                 |
  +-----------------+

===== Copy the public key using ssh-copy-id =====

Copy the public key to ace-storage-2 using ssh-copy-id

  ssh-copy-id -i ~/.ssh/id_rsa.pub <your_user>@ace-storage-2.cbrain.mcgill.ca
  
===== Test SSH login =====
  
You should be able to login without requiring your password

===== Install SSHFS =====

  sudo apt-get install sshfs

===== Mount Points =====

A mount point is a directory on your system where the content in a remote directory appears on your workstation. The standard location for mount points on linux and unix systems us `/mnt`.

IMPORTANT: To ensure that mount points continue to work and are still available (not clobbered) when LDAP mounts users home directories to `/home/username` we will avoid mounting file systems to users current home directories and use the standard convention of mounting file systems to the designated temporary mount point `/mnt` as described in the [[https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard]] and illustrated in the examples below:

Syntax

(using all lower case)

  /mnt/<user name>/< short host name >-< directory >

==== Mount Point Examples ====

  /mnt/asmith/storage-2-home
  /mnt/asmith/storage-2-shared
  /mnt/asmith/storage-2-datasets

===== /etc/fuse.conf =====

Ensure that `user_allow_other` is in /etc/fuse.conf and that it is uncommented so that users are able to mount file systems. (Our current LDAP configuration requires this as well).

  user_allow_other

2. Connect it to the data directory on ace-storage-2

Syntax

  sshfs < user name >@< server name >:/path/to/some/data <mount point>
  
Example

  sshfs asmith@ace-storage-2.cbrain.mcgill.ca:/home/users/asmith /mnt/asmith/storage-2-home
  
More information and options are described in [[https://wiki.archlinux.org/index.php/sshfs]]

===== Mount Directories Permanently =====

[[https://wiki.archlinux.org/index.php/sshfs]]

Edit the **fstab** on your workstation

  sudo vi /etc/fstab
  
Add the following

  <your_user>@ace-storage-2.cbrain.mcgill.ca:/home/users/<your_user> /mnt/<your_user>/storage2-home fuse.sshfs defaults,_netdev,identityfile=/home/<your_user>/.ssh/id_rsa,uid=<your_UID>,gid=<your_GID>,user,allow_other  0   0
  <your_user>@ace-storage-2.cbrain.mcgill.ca:/data1/ACElab_Shared /mnt/<your_user>/storage2-shared fuse.sshfs defaults,_netdev,identityfile=/home/<your_user>/.ssh/id_rsa,uid=<your_UID>,gid=<your_GID>,user,allow_other  0   0
  <your_user>@ace-storage-2.cbrain.mcgill.ca:/data1/Raw_Study_Data /mnt/<your_user>/storage2-datasets fuse.sshfs defaults,_netdev,identityfile=/home/<your_user>/.ssh/id_rsa,uid=<your_UID>,gid=<your_GID>,user,allow_other  0   0
