Rolling reboots on owens and pitzer starting 26 July 2021
We will have rolling reboots of Owens and Pitzer cluster, including login and compute nodes, starting from 9am on July 26, 2021. The rolling reboot is for urgent security updates. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. User will also expect about a 10 minute outage of login nodes during the reboot of login nodes. If there are interactive jobs started from a login node and that login node is rebooted, then the job will be killed.
Please review your usage of /fs/ess
Recent improvements to a routine OSC accounting process resulted in larger adjustments to file counts and quota usages than anticipated for some accounts. The updated metrics are more accurate but some users may now have less free space than expected. Please review your usage closely and, if necessary, remove unneeded data or request a quota expansion via OSCHelp to avoid exhausting your available space.
Multi-factor authentication
MyOSC now supports multi-factor authentication (MFA).
User opt-in
Users can now opt-in to using multi-factor authentication in MyOSC.
On a user's profile page, there will be a button Enable DUO MFA.
