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?
First thing I would suggest is to let everyone know the status of the current array, and how to get it working.
Can you send the output of cat /proc/mdstat and mdadm --misc --detail /dev/md?
Assuming the existing array is in a "normal" status, albeit degraded, then it should be pretty simple to just partition the new drive to match the other members, and then simply add the new partition to the array (mdadm --manage /dev/md? --add /dev/sdxy)
Try to take things slowly, as doing the wrong thing might make a simple recovery into a very sad event (loss of all the data).
