Troubleshooting CRSP Issues

The following sections have information on how to solve most common problems. If they did not resolve your issue, contact CRSP support at hpc-support@uci.edu

1. WebDrive

As of Spring 2021 we no longer support WebDrive. Please see this guide for CRSP Desktop installation instructions for Windows or Mac.

2. CRSP Desktop

Please note that RCIC does not provide Windows OS or macOS support for the campus. If there is an operating system related issue, RCIC will refer you to you get support to address your systems issue first before installing CRSP Desktop.

2.1. Unable to install CRSP Desktop on Windows

If you are having issues installing RCIC provided CRSP Desktop, check the following:

  • Make sure your system meets minimal requirements listed in the install guide for Windows

  • If previous version of CRSP Desktop (or Mountain Duck) is installed, uninstall it. Go Windows → Add or Remove Programs, check for CRSP Desktop (Mountain Duck). If found, uninstall any previous installations, reboot the system and retry installation using RCIC provided version.

  • Check for any obvious errors or warnings on the computer

2.2. Unable to install CRSP Desktop on macOS

If you are having issues installing RCIC provided CRSP Desktop, check the following:

  • Make sure your system meets minimal requirements listed in the install guide for Mac

  • Make sure you have Admin rights in your system. If your system is managed by OIT, ask your support team to give you Admin rights.

  • If previous version of CRSP Desktop (or Mountain Duck) is installed, uninstall it. Under Applications, look for any CRSP Desktop or Mountain Duck installations. If found, drag the App to trash, and retry installation using RCIC provided version.

2.3. Share not visible or share is empty

This could be caused by several reasons:

  • disconnect from share after computer came back from sleep, or hibernation mode

  • not connected via UCI VPN

  • network connectivity is poor or network is down

Resolution:

  • Ensure your system is connected to UCINET or home internet. Restart system if necessary, to restore internet connectivity. If you are off campus, make sure you are logged onto UCINET with VPN.

  • If the above does not solve your issue, try deleting the share bookmark from CRSP Desktop, and recreate it anew

2.4. Authentication failure, unable to login

This could be caused by one or more reasons:

  • You don’t have an account created for CRSP. [red]* Please note that HPC3 and CRSP * accounts are separate*. You may have an HPC3 account and may not have CRSP account.

  • Your UCINET password is incorrect

  • Your CRSP home directory is over quota

  • There might be a technical issue at CRSP infrastructure systems

Resolution:

  • If you don’t have an account for CRSP, apply for one.

  • Make sure your UCINET password is correct.

  • Make sure you are on UCINET or connected via UCI VPN

3. SSHFS

When a user is unable to access share via sshfs, it may be caused by:

  • Network issues. For example, slow network connection, unstable network connections

  • CRSP share is unavailable

Resolution:

  1. First step: unmount the share

    $ fusermount -u ~/<sharename>
  2. Second step: remount the share

    $ sshfs <username>@crspssh.crsp.uci.edu:/mmfs1/home/<username> ~/<sharename>

4. Browser Based Access

Please note that Browser based access is for lightweight use cases. Typical use case would be for someone who does not have access to CRSP Desktop, or SSHFS. The following are the known limitations of Web based access method:

  • It may take longer to populate the file browser if there are lots of files in a directory. In our lab tests, we were able to load around 2000 files in the file browser.

  • Uploading large size files with file browser can be hectic if you have slow internet connection, or if your connection is interrupted. If you have large data sets, use:

  • Running the File Browser in Firefox does not provide the best user experience. Chrome or Safari seems to work better.

  • Since the File Browser works with campus shibboleth authentication, it will timeout and expire as soon as browser authentication expires. That means a re-authentication will be required.

  • If you encounter UCI DUO authentication issues, you will not be able to logon to CRSP web based access. For more information on UCI campus DUO authentication questions or issues, visit OIT DUO authentication page.
