Describe the differences among RAID 0,1,4, and 5
Select from among the RAID levels given a set of performance, cost, and risk mitigation criteria
Install the requisite packages and kernel patches/modules for RAID (software and hardware) and LVM
Configure soft-RAID, LVM and possibly combinations of them as appropriate to specific needs
Understand limits and mitigate the risks posed by RAID (i.e. monitor for and recover from “degraded mode”)
Configure Linux systems to support booting on a soft-RAID set as its root filesystem
Understand LVM terms such as VG (volume group), PV (physical volume) LVM (logical volume) and concepts such as resizing and “online resizing”
Chapter 7: File Sharing and Services – NFS Create an exports and specify filesystems to be exported
