Install Genders and PDSH
A combination of genders and pdsh can allow for management and monitoring of multiple nodes at a time.
This only needs to be done on the head node.
Swap to the head node (unless already on it).
dnf install -y flight-pdsh
Navigate to the genders file at
/opt/flight/etc/genders, and open it.
Add a gender in the following format to the genders file. Then save and close the file.
Log out and log back in for the environment to load.
If all was successful, then the following should be the case on the head node:
The following commands should run without errors:
nodeattr -s nodes
pdsh -g nodes uptime
/opt/flight/etc/gendersshould contain genders for use with the installed commands.
