Disabling short circuit write

This section describes how to disable short circuit write.

Note: By default, the short circuit write is enabled only if the short circuit read is enabled.
  1. Go to Ambari GUI > Spectrum Scale > Custom gpfs-site, add the gpfs.short-circuit-write.enabled=false property, and save the configuration.
  2. Restart IBM Spectrum Scale service.
  3. Restart HDFS service.
  4. Restart any services that are down.
    Note: If gpfs.short-circuit-write.enabled is disabled, there will be a lot of traffic over the local network lo adapter when you run a teragen job.
