Past Incidents

9th July 2021

Holyscratch01 (Global Scratch) holyscratch01 slowness over LNET

holyscratch01 is under heavy load making it slow over the LNET routers (anything connecting via ethernet or FDR fabric, this would include the login nodes). Nodes connected via the HDR fabric (test and shared partitions) look to be fine though a little slow at times.

ncf_bigmem down

Jobs currently cannot be started on ncf_bigmem partition.
