Post-Installation Tasks
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.
