Introduction to Storage System - 2

* Storage File Syetem: Adding hard disk (hdd)
        - physical hard disk add: /lost+found
#fdisk -l
#mkfs.ext3 /dev/sdc1
        - adding new partition, file system type: ext3
#mkdir /mydata
#mount /dev/sdc1 /mydata
# vi /etc/fstab
        - fstab file modifying
#e2label /dev/sdc1 /mydata


* Logical Volume Manager (LVM)
        - physical volume -> volume group -> logical volume
        - adding partition -> setting LVM (from <t> to <fe>) -> physical volume (#pvcreate /dev/sdc1) -> LV creation (#vhcreate VolGroup01 /dev/sdh /dev/sdi    #vgdisplay) (type: exxt3) (#mkfs.ext3 /dev/VolGroup01)
-> LV partition creation (#lvcreate --size=xxMB --name [LV_name] [VG_name]    #lvdisplay    #lvscan) -> file system mounting (#mount /dev/... /data2)

* Increase LV Size
#lvextend --size ...
#e2fsck -f /dev ...
#resize2fs /dev/.../Log01

* Setting hdd Raid Level
distribute partition
#fdisk /dev/... ID=Fd
#ls -l /dev/md*
#mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/... /dev/...
#mdadm -scan
#mkfs.ext3 /dev/md0
#mount
#vi /etc/fstab
