Greetings My raid 10 array was the subject of a number of exchanges on this board a few months ago. With the generous assistance of members here things were reestablished and have been working well. Today I had a VirtualBox VM crater and in the process cause other system issues. In process to clear the mess a number of hard stops (shutting the system off using the button on the case) were used. In rebooting I found that one of the drives in the array is no longer responding issuing a number of clicks in the boot up process with nothing else happening. Even though it is a RAID 10 array the array is no longer mounted nor available. I have removed the faulty drive already. I have an appropriately sized drive available that I could place into the machine. 1. should I reformat the drive (to be placed into the machine)? 2. what sequence of commands should I be using for this new drive to be included into the array? 3. what sequence of commands should I use to remount the array?
