Linux Configuration Settings
Certain Linux configuration settings should be set on each node to run the installation.
We recommend the following settings, which should be performed on each node.
• (Optional) Check that the Linux OS allows overcommitting of virtual memory:
cat /proc/sys/vm/overcommit_memory # Should return 1
ulimit -v # Should return unlimited
• Check the number of open files set by the installer:
ulimit -n
This number should be large, for example, 30,000.
