CentOS 7. I have a server with four drives. 1 is /, and the other three are in RAID5. I need to pull a drive, so I can test whether the server can read > 2TB drives. I've been googling, but don't want to screw the server up.... I think I'd like to 1. stop the RAID 2. pull a drive 3. put in a large drive, and run parted, and mkfs 4. pull the large drive 5. replace the RAID drive 6. fire up the RAID. So, can I do it in that order? Do I need to fail something? mark
