I have server and there is one 1TB drive in it and I guess it's not running any raid, I'm thinking if it's possible to add another 1TB HDD and setup RAID1 somehow?(software raid1)Server is running CentOS 6.4Is it possible to do that?Would it occur any downtime, perhaps data loss?How simple is it?
Possible to get RAID1, by simply adding HDD?
linux;centos
