RAID

Check the Raid installed lspci | grep RAID     Software Raid ============== Linux Support For Software RAID Currently, Linux supports the following RAID levels (quoting from the man page): LINEAR RAID0 (striping) RAID1 (mirroring) RAID4 RAID5 RAID6 RAID10 MULTIPATH, and FAULTY. MULTIPATH is not a Software RAID mechanism, but does involve multiple devices: each device is a path to one common physical storage device. FAULTY is also not true RAID, and it only involves one device. It provides a layer over a true device that can be used to inject faults. Install mdadm Type the following command under RHEL / CentOS / Fedora Linux: # yum install mdadm Type the following command under Debian / Ubuntu Linux: # apt-get update && apt-get install mdadm How Do I Create RAID1 Using mdadm? Type the following command to create RAID1 using /dev/sdc1 and /dev/sdd1 (20GB size each). First run fdisk on /dev/sdc and /dev/sdd with " Softwa...
