3 250 gb SSD do raid5 + 2 TB hard disk backup
Problem:
At present three SSD has been using 80%, need to upgrade solid-state drives, this is a web server, because the system Settings is complex, so it is not reshipment system to upgrade the hard disk,
So

3: it is no way out, whether the system directly ghost backup and then restore to a 1 TB of solid-state disk continue to plug up use raid5 (removed)
Key: give rewards, whether the entire guide operation? Thank you, please direct messages.
