{{Warning box|This howto is intended as a guide to set a new server which has no existing data, do NOT run this on a live server without a backup of that system.}}
===Installing required tools===
You will need to install some additionally tools
yum Install parted
yum install xfsprogs
It’s usually a good idea to run… but not required
Signal-event post-upgrade;
Signal-event reboot;
When new disks are added, existing raid partitions can be grown to use the new disks. After the new disk has been partitioned, the RAID array 1/4/5 may be grown. Assuming that before growing, it contains four drives in Raid5 and therefore an array of 3 drives (3*10G) and 1 spare drive(10G). See this [[Raid#Hard_Drives_.E2.80.93_Raid|HowTo]] for understanding the automatic raid construction of SME Server
