Quest and Kellogg Linux Cluster Downtime, March 22 - 31.
Quest, including the Quest Analytics Nodes, the Genomics Compute Cluster (GCC), the Kellogg Linux Cluster (KLC), and Quest OnDemand, will be unavailable for scheduled maintenance starting at 8 A.M. on Saturday, March 22, and ending approximately at 5 P.M. on Monday, March 31. During the maintenance window, you will not be able to login to Quest, Quest Analytics Nodes, the GCC, KLC, or Quest OnDemand submit new jobs, run jobs, or access files stored on Quest in any way including Globus. For details on this maintenance, please see the Status of University IT Services page.
Quest RHEL8 Pilot Environment
The RHEL8 Pilot Environment is available for use now.
Ahead of the March 2025 Downtime, Quest users have the opportunity to test their software and research workflows on CPU nodes and NVIDIA H100 GPU nodes which are running the new RHEL8 OS. Detailed instructions are available on how to submit jobs for the new Operating System in the Knowledge Base article, RHEL8 Pilot Environment.
RHEL8 Pilot Quest log-in nodes can be access via ssh or FastX through using the hostname login.quest.northwestern.edu. Please note that the new hostname login.quest.northwestern.edu will require the GlobalProtect VPN when outside of the United States.
RHEL8 Pilot Quest Analytics nodes can be access via: rstudio.quest.northwestern.edu, jupyterhub.quest.northwestern.edu, and sasstudio.quest.northwestern.edu.
Server Message Block (SMB) protocol is a communication standard that computers use to share access to files, printers and other resources on a network. Specifically, we use it to connect to shares on the Research Data Storage Service (RDSS) and fsmresfiles. The various versions (SMBv1, SMBv2, and SMBv3) are referred to as dialects. The RDSS server currently supports all three dialects. Your system also supports one or all these dialects.
Knowing which dialect you use to connect to RDSS is important because SMBv1 lacks the following features:
- It will not reconnect automatically if you are disconnected due to server maintenance or lost network connection.
- It does not support encryption, leaving your computer open to ransomware and other types of cyberattacks.
We recommend disabling SMBv1 if you can. This document describes
- how to find out if system supports SMBv2/3,
- how to check what dialect you’re using to connect to RDSS, and
- what to do if you're using SMBv1.
Does my system support SMBv2/3?
Many systems support multiple SMB dialects to increase compatibility with servers they need to connect to. Which SMB dialects are supported is determined by the operating system version on Mac and Windows and by the samba package version on Linux systems.
Systems running the following software support SMBv1 only.
If your system only supports SMBv1, we recommend upgrading your operating system or samba version to enable a newer SMB dialect if possible. Be sure to check that upgrading will not affect compatibility with software and instruments you need to use for your research.
What version of SMB am I using to connect to RDSS?
Your system typically uses the most current SMB dialect that both your machine and the server have in common. However, newer dialects may be disabled, preventing them from being used. The following system-specific instructions will show you how to determine which version of SMB you are using to connect to RDSS. If you are using major version 2 or 3, no action is necessary.
MacOSX
- Connect to your RDSS share
- Open a Terminal window (Applications > Terminal).
- Type the following command:
smbutil statshares -a
In the resulting list of information, look for the attribute SMB_VERSION. The value of this indicates your SMB version. The value is in the format SMB_X.Y.Z, where X is the major version.
Windows
- Connect to your RDSS share
- Click Start, type PowerShell, and right-click Windows PowerShell, then click Run as administrator.
- Type the following command:
Get-SmbConnection
Your SMB version is listed in the Dialect field in the format X.YZ where X is the major version.
Linux
- Connect to your RDSS share
- Open a Terminal window
- Type the following command:
sudo smbstatus --version
Your SMB version is listed in the Protocol Version field in the format SMX_YZ where X is the major version.
What should I do if I'm using SMBv1?
- If your system only supports SMBv1, consider upgrading your operating system or samba package if possible. Be sure to check that upgrading will not affect compatibility with software and instruments you need to use for your research.
- If your system supports other SMB dialects, contact rdss-help@northwestern.edu for advice on how to configure your machine to use a more current version.
