In order to prepare future improvements of the parallel
/scratch file system, as well as performing some required work on the scheduler, Sherlock will not be available during the following times:
Wednesday, October 16th, 2019 - from 8:00am to 6:00pm
Access to Sherlock will be unavailable, logins will be disabled and jobs won’t run during that period.
Note: if you submit a job on Sherlock before the downtime and the time you request exceeds the time remaining until the maintenance begins, your job will run when the maintenance is over. The hours leading up to the maintenance are often a good time to submit shorter, smaller jobs that can complete before the maintenance begins: as the queues drain there will be many nodes available, and your wait time may be shorter than usual.
Oak storage will stay online during Sherlock’s maintenance, including all its gateways. If you need to access files on Oak during that time, you can use Globus, the shared DTN (eg. SSHFS), or other private NFS/SMB Oak gateways if you have any.
