Dear JASMIN user,
This is the final reminder to please note the upcoming maintenance day Tomorrow, Tuesday 11th July. The following system work/enhancements are also planned for that date in order to minimise disruption:
Disable write access to the old scratch area
The old volume
/work/scratch-nopw has previously been announced as out of service but the following steps will now implement this:
/work/scratch-nopwwill be made read-only from 11th July with no access after 18th July 2023
/work/scratch-nopwshould be copied from that location before 18th July 2023
Increase the size of the current SSD scratch area
The size of
/work/scratch-nopw2 will be expanded from 90TB to 200TB. The per-user quota limit of 5TB will be increased.
Slurm configuration update
As part of the continuous improvement to the Slurm scheduler, new features will be enabled on the scheduler to manage the load and control resources allocation for accessing the queues.
Changes to network routing
Some network changes are planned to enable new storage hardware to be accessible throughout JASMIN.
Changes to the cloud firewall
The firewall serving the JASMIN community cloud is to be replaced.
The LOTUS batch processing cluster will be unavailable for the duration of the work on the day, to avoid running jobs being adversely affected. A reservation will start at 05:00 am on 11th July till 23:59 pm on the day, but any job submitted before 04:00 am with a running time that goes over the reservation period will not start until after the reservation has finished.
Please note all the above updates and plan your work accordingly to minimise any inconvenience caused.
Thank you for your attention.
