Mount storage over SSH using sshfs

To exchange data quickly between your laptop and our clusters, you can mount your cluster home directory on your laptop or workstation with sshfs. It then behaves like a local folder. Phoebe and Koios have separate home directories; the examples below mount your Phoebe home.

Prerequisites

• configured key-based authentication
• a phoebe host entry in ~/.ssh/config, as described in SSH:

Host phoebe
        Hostname phoebe.fzu.cz
        User <username>

Create mount aliases

LinuxmacOS

Into your local ~/.bashrc (if you use bash), insert this snippet. Replace johndoe with your cluster username.

phoebe_username='johndoe'

alias mount_phoebe="mkdir -p ~/phoebe_mount && sshfs -o reconnect,ServerAliveInterval=2,ServerAliveCountMax=3 phoebe:/home/${phoebe_username} ~/phoebe_mount"
alias umount_phoebe='fuser -Mk ~/phoebe_mount; fuser -Mk ~/phoebe_mount; fuser -Mk ~/phoebe_mount;  fusermount -u ~/phoebe_mount'

Load the changed ~/.bashrc:

source ~/.bashrc

sshfs on macOS needs macFUSE and its sshfs package.

Open ~/.zshrc in your favorite editor (or create it when missing) and insert this snippet. Replace johndoe with your cluster username.

phoebe_username='johndoe'

alias mount_phoebe="mkdir -p ~/phoebe_mount && sshfs -o reconnect,ServerAliveInterval=2,ServerAliveCountMax=3 phoebe:/home/${phoebe_username} ~/phoebe_mount"
alias umount_phoebe='umount ~/phoebe_mount'

To make sure that ~/.zshrc is loaded in every new shell, edit ~/.zprofile and insert:

[[ -s ~/.zshrc ]] && source ~/.zshrc

Mount and unmount

In a new shell, type mount_phoebe to mount your cluster home directory into ~/phoebe_mount. Type umount_phoebe to unmount it.
