How to Mount Folders from the Large Scale Storage System

Page

We will discuss mounting the LSS systems from the following system types:

  • Mac OS X
  • Windows
  • Research IT and/or Biology IT Linux Servers
  • Condo Research Cluster
  • Linux GUI Desktop (Gnome)

The following examples will use the values:

  • jones, as your P.I.'s Net-ID, and
  • you, as your ISU Net-ID.

This means you will need to substitute your PI's Net-ID for jones and your NetID for you. The naming convention for all LSS research folders is based on the Net-ID of your PI and has the format netid-lab. Thus, our example LSS folder is called jones-lab.

If you have problems, please contact your local departmental IT support technician, or email lss-help@iastate.edu

Mounting from Mac OS X

  • From the Finder application menu item "Go" select "Connect to Server"
  • Enter smb://iastate/lss/research/jones-lab as shown here:

Mac dialog box for connecting to LSS

​If a login prompt is received:

  • Enter IASTATE\you in the username field.
  • Enter your Net-ID password in the password field.

Mac OS X likes to write small metadata files named .ds_store to every filesystem it encounters. These files are used to store things like icon position in the Finder. The writing of these files can slow down your experience with LSS significantly, and we recommend that you tell your computer to not write these files to network drives by issuing the following command in Terminal:

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true

You only need to do this once on your computer.

Mounting from Windows

1. Open a Windows Explorer window

2. Type this: \\iastate\lss\research\jones-lab

Connecting to LSS with Windows Explorer

​If a login prompt is received:

  • Enter IASTATE\you in the username field.
  • Enter your Net-ID password in the password field.

Mounting from BigRam, BioCrunch, Speedy, Legion, RIT1/2, etc.

When you log into biocrunch, bigram or speedy for the first time, create a short symlink to the LSS path to your lab. For example, if the netid of your PI is jones:

$ ssh you@bigram.ent.iastate.edu

​$ cd ~

$ ln -s /lss/research/jones-lab jones-lab

​From then on, you can access the LSS from the jones-lab directory in your home folder.

Note: Do not run jobs against data in the jones-lab directory, as it is just a mount of a remote volume. Instead, copy files from from the jones-lab directory to your home directory, which is local storage to the machine. You can then run jobs against the data in your home directory.

Mounting from Condo cluster

  • Login to the condo cluster head node using the regular procedure.
  • Use ssh to access condodtn from the Condo cluster head node.
  • Navigate to your research folder, which is under /lss/research.
    • Remember that the folder is named for your PI's Net-ID (netid-lab)
    • You should always copy files from this location into /work/LAS as needed to run your jobs. Results should be copied back to your research folder when finished.

$ ssh condodtn

​$ cd /lss/research/netid-lab

Mounting From Linux GUI

  1. Choose "Windows Share" from the Type dropdown.
  2. Connection Information:
    • Server: las-dfs-01.las.iastate.edu
    • Share: lss
    • Folder: research/jones-lab.
  • First, open the Files application and choose the "Connect to Server" option in the left-hand access bar.
  • In the "Connect to Server" dialog box,
    • The connection string is in the format smb://<server>/<share>/<folder>.
      • Using our example values, the connection string would be smb://las-dfs-01.lasf.iastate.edu/lss/research/jones-lab
    • Click the "Connect" button
  • In the authorization box, type in your ISU Net-ID, Domain, and Password.
    • Domain: IASTATE
    • Username: you
    • Password: your-password

Mounting over VPN:

There is currently an issue with using the default address over VPN, and often from personally owned or non-domain joined devices.  If you are mounting LSS over VPN you will need to use this alternate address:

las-dfs-01.las.iastate.edu/lss/research/jones-lab

Instead of:

iastate/lss

The other steps for your operating system remain the same as listed above.

Regarding Permissions:

Permissions to the shared folders are controlled on the server back-end and may not display correctly on your client. This has no impact no the enforcement of permissions. Your files are only accessible by people in the group that you have authorized.
