Some issue not addressed yet in this guide

• Account synchronization between FE - What will happened if a user change password on a FE? It will not reflected to the 2nd FE immediately until “rocks sync frontend” is run.

• NAS storage fail-over - I think you should get some idea already after following this guide.

• Compute node re-installation on any FE - The cluster that I set can install a custom appliance node from FE1 successfully. However, I don’t sure if this also apply to 2nd FE. Seems that some configuration is not yet generated correctly.
