Reboot login node?


My login node on the the AWS console is failing some tests and I can’t connect via ssh anymore. Will the compute nodes be affected by a reboot of the login node?



Hi JJ,

Thanks for your interest in Alces Flight!

By default on a Flight Solo cluster, the login node provides the shared storage for your compute nodes, so rebooting it may affect any running jobs. This will depend on what the nodes are currently doing, and why the login node is failing AWS checks.

Did you make any changes on the login node that might cause it to be un-contactable?



Hi Will,

Sorry to take so long to answer. I found that the communication between the node failed and no jobs ran, so I started a new cluster from scratch and that worked.
