This article describes one of the possible reasons for slow boot times observed on some Linux based servers.
Symptom:
Slow Boot times / Target appears to be stuck and might not boot.
Before you Begin:
During the migration planning phase, identify VMs configured with services like ypbind
Use case:
Applicable to BOTH Migration and DR SYNC's using RMM for Linux servers
Applicable To:
VMs with network services like ypbind / NIS configured to start on boot
Preparation/Pre-Req:
You will need 'root' level access to the ORIGN server and 'ADMIN' level access to RMM GUI, or 'root' access to RMM CLI
Steps:
Disable ypbind on ORIGIN prior to migration - chkconfig ypbind off
OR
Use the --no-reboot RMM SYNC option to perform initial migration and delta syncs.
For the final cut-over sync, disable the ypbind service using "chkconfig ypbind off" command on the ORIGIN server and uncheck --no-reboot option from RMM SYNC options.
Important Note(s):
Re-enable the service after migration cutover on the target using "chkconfig ypbind on"
