Issue/Introduction

The imexutil script takes a long time to import/export artifacts in new OS.

Environment

Release : 12.x

OS: Linux / UNIX

Cause

The level of available entropy on the server may be extremely low. This is common on VMs that are not heavily utilized.

Resolution

Run the following command to monitor the available entropy on the server.

watch -n 1 cat /proc/sys/kernel/random/entropy_avail

Ideally, the available entropy on the server should be at a minimum of 1000 to avoid issues with the agent initializing the encryption routines. 

 

Consult System Administrator to enable 'rngd' service to increase the entropy.

 

E.g.

systemctl enable rngd.service
