SUMMARY:Monthly maintenance Dec 5th 2022 7am-11am
DESCRIPTION:Regular monthly maintenance will take place Monday Dec. 5th, 2022 7-11am\nNOTICES\n\nGPU PARTITIONS\nDue to failed nodes, the gpu_test partition is down to 2 nodes and the (single node) remoteviz partition is down at the moment. We are working with the vendor to replace hardware, but this is still unresolved and no ETA at this time. Additionally, when it rains it pours, some nodes in the gpu queue are offline but we hope to be able to revive them with a visitto the data center tomorrow (12/1/22)\nGLOBUS PERSONAL CLIENT - UPDATE BY DEC 17\nIf you are using the Globus Connect Personal client on your machine, please ensure you have updated and are running version 3.2 or greater by December 17th, 2022. You will not be able to use version 3.1 or below after that date.\nhttps://docs.globus.org/ca-update-2022/#globus_connect_personal ( https://docs.globus.org/ca-update-2022/#globus_connect_personal )\nHOLIDAY NOTICES NOVEMBER: \nOffice Hours will be held on 11/23 prior to the Thanksgiving break, but will run only from 12-2pm.\nFASRC staff will be unavailable Nov. 16th from 12-3pm for a staff event.\nThur/Fri Nov. 24th and 25th are university holidays (Thanksgiving).\nHOLIDAY NOTICES DECEMBER:\nOffice Hours will not be held on Dec. 21st and will resume Jan. 4th, 2023.\nWinter break runs Dec. 23 - Jan. 2nd. FASRC will monitor for emergencies during this time, but general questions/tickets will be held until we return on Jan. 3rd, 2023. \n\n\nSlurm scheduler update notes: \n\nGiven a bug in the previous versions of Slurm, this upgrade will create a situation where jobs launched on the previous version will get stuck in COMPLETING state until the node is rebooted (see: https://bugs.schedmd.com/show_bug.cgi?id=15078). This means in the week(s) following the upgrade there will rolling reboots of the nodes to clear these stuck jobs.\nUsers should be aware that any jobs stuck in COMPLETING state will remain so until the node the job lives on is rebooted, and any node that is labelled COMPLETING will not be able to receive jobs until it is rebooted. This is due to a Slurm bug and nothing to do with the users code or jobs and thus the users cannot do anything to clear this state faster. FASRC admins will reboot nodes as soon as they are clear of work to fix this issue.\n\n\n\nGENERAL MAINTENANCE \n\nSlurm scheduler update (22.05.x) - See notes above\n\nAudience: All cluster job users\nImpact: =See notes above.= The scheduler and job will be paused during upgrade. \n\n\nPartition decommissioning\n\nAudience: narayan and holymeissner partition users\nImpact: This partition(s) will no longer be available\n\n\nDomain controller DHCP updates\n\nAudience: All users\nImpact: No impact expected\n\n\nFASRC ticket system maintenance\n\nAudience: All users\nImpact: The ticket system and it's database  will be offline during maintenance, but\nany ticket emails will queue and be delivered once maintenance is complete\n\n\nHolyscratch01 firmware updates\n\nAudience: All users of scratch\nImpact: Scratch will be unavailable for short periods\n\n\nLogin node and VDI node reboots and firmware updates\n\nAudience: Anyone logged into a a login node or VDI/OOD node\nImpact: Login and VDI/OOD nodes will be unavailable while updating and rebooting\n\n\nScratch cleanup ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ )\n\nAudience: Cluster users\nImpact: Files older than 90 days will be removed.\nReminder: Scratch 90-day file retention purging runs occur regularly not just during maintenance periods.\n\n\n\nUpdates on our status page: https://status.rc.fas.harvard.edu ( https://status.rc.fas.harvard.edu )\nThanks!\nFAS Research Computing\nDepartment and Service Catalog: https://www.rc.fas.harvard.edu/ ( https://www.rc.fas.harvard.edu/ )\nDocumentation: https://docs.rc.fas.harvard.edu/\nStatus Page: https://status.rc.fas.harvard.edu/\n \n
