I'm a first time poster so please bear with me.
I have a Redhat 9 system with a hardware Raid 5 (Dell Poweredge 2650 w/ Perc 3/di controller) with 3 drives and 2 empty slots.
The /usr partition is low on disk space due to a growing db.
I have been given the task of adding two additional drives into the two empty slots, same make/model/size HD's.
The plan is to create a Raid 1 with the two new drives then move the folder holding most of the data to the new partition then create a symbolic link to the new location.
I am not an expert in Linux so I was wondering if this a sound plan am I missing something? do I run the risk of not being able to boot , lose data?
