Home Directories

All user home directories for the department are now stored on ZFS storage located in the “003” server room in Rice Hall. ZFS is a widely used, industry-standard storage platform that offers modern features such as backups/snapshots. User data is stored on a Nexsan E-Series storage appliance capable of scaling to 6 petabytes in a single 42U server rack. The disk arrays in this device are connected to a SAN (storage area network) via 8Gb fiber-channel and served over NFS by servers running Solaris.

There are four servers serving ZFS partitions:

ServerPartitions, /zf20-zf25, /if1-if6, /af1-af5, /af11-af12, /af25-af26
NFSCS filesystems are exported via NFS to department-managed Unix systems - Linux and Solaris interactive and compute nodes. Filesystems are mounted consistently across all nodes so the paths are identical no matter what node you are working on. If you have root on your own desktop or laptop, we do not export NFS to your machine, you'll need to use SMBFS/CIFS.
Samba/CIFSUsers logging into their “CSDOM” Windows account will automatically find their home directory mounted as their “K:\” drive.
Anyone can mount their home directory using Samba on their personal computers. Windows, Linux and Mac OS all have clients that will allow you to mount your CS department home directory over Samba.
SCP/SFTPFor truly remote access, we recommend using an SCP/SFTP client: the openssh package available on almost all *nix based systems - Solaris, Mac OS-X and the Linuxes. For Windows platform users, openssh is part of the cygwin packages, and ITS also provides SecureFX at ITS Software Central. For these connections, you should use the hostname to access the files; direct access to all file servers is restricted to Samba and NFS services.

You can use scp or sftp to access our filesystems through any given CS Linux server. We recommend that you use the host for scp or sftp connections.

We have a new central Samba server that everyone can use to connect to their home directory. To connect to your home directory, use the following network share:


When asked to authenticate please format your usename like this:


GUI Programs

Graphical file managers under Linux and Mac OS (e.g. Nautilus, Finder, Caja, etc.) allow you to enter your network path using the following formatting

smb://     or     smb://

You may be required to specify a user name in this path. If you are not asked for a username and password, try adding your username like in the second example. If you are asked for a domain or workgroup, use CSDOM.

CLI Mount

You can mount your directory from the command line. First, make sure that you have the cifs-utils package installed.

For Debian/apt based distributions:

sudo apt-get install cifs-utils

For Red Hat/yum based distributions:

sudo yum install cifs-utils

And then run the following command to mount your home directory

sudo mount -t cifs -o username=ktm5j //zfs3/zf15_smb/ktm5j /mnt/
