Utilizing SSHFS for Distributed Computing

What is SSHFS

• SSHFS allows you to mount data through an ssh connection. – http://fuse.sourceforge.net/sshfs.html

– http://wikipedia.org/wiki/SSH_Filesystem• Simple command line

– sshfs remoteuser@remotehost:/path/to/remote_dir local_dir

• Performance is as fast as your ssh connection.

• Works on Linux. (i386, x86_64, ia64)

mailto:remoteuser@remotehost

Why use sshfs?

• Allows you to use local applications on remote data.– using Paraview to look at data processed on

the TeraGrid and stored on the GPFS-WAN.• Directly accessing the remote file. Your

changes are seen by everyone. • SSHFS allows you to tune performance.

Easy to install on Linux

• Ubuntu – sudo apt-get install sshfs

• CentOS (x86_64 example)– download fuse (http://fuse.sourceforge.net)

• ./configue --prefix=/usr --libdir=/usr/lib64

– download sshfs• ./configure –prefix=/usr –libdir=/usr/lib64

– /etc/rc.d/rc.local• mknod /dev/fuse -m 0666 c 10 299

Advanced Sys. Adm. Tricks

• Utilize SSHFS with autofs to mount remote data for local users

• Utilize samba to share SSHFS with windows users

• Utilize SMBWebClient to share data through a web portal.
