Create a Logical Volume using Linux LVM
\nThis example uses a local hard disk to create a logical volume.<\/p>\n
1. partition the disk as normal using fdisk. I new the fdisk options ahead of time from having done this before.<\/p>\n
EDS etldev1 ~ # FDISK_CMDLIST=”n\\np\\n1\\n\\nt\\n8e\\nw\\n”
\nEDS etldev1 ~ # echo -e -n “${FDISK_CMDLIST}” | ( fdisk \/dev\/sdc )
\nThis is the same thing as doing it from the fdisk menu as follows:<\/p>\n
EDS etldev1 ~ # fdisk \/dev\/sdc<\/p>\n
WARNING: DOS-compatible mode is deprecated. It’s strongly recommended to
\n switch off the mode (command ‘c’) and change display units to
\n sectors (command ‘u’).<\/p>\n
Command (m for help): n

\n e extended
\n p primary partition (1-4)
\np
\nPartition number (1-4): 1
\nFirst cylinder (1-17769, default 1):
\nUsing default value 1
\nLast cylinder, +cylinders or +size{K,M,G} (1-17769, default 17769):
\nUsing default value 17769<\/p>\n
Command (m for help): t
\nSelected partition 1
\nHex code (type L to list codes): 8e
\nChanged system type of partition 1 to 8e (Linux LVM)<\/p>\n
Command (m for help): w
\nThe partition table has been altered!<\/p>\n
Calling ioctl() to re-read partition table.
\nSyncing disks.
\n2. Initialize the partition for use by LVM using pvcreate.<\/p>\n
3. Create a volume group using the block device specified in pvcreate<\/p>\n
4. Create a logical volume in the volume group from step 3<\/p>\n
Steps 2, 3, 4 are illustrated below<\/p>\n
EDS etldev1 ~ # pvcreate \/dev\/sdc1
\n Physical volume “\/dev\/sdc1” successfully created<\/p>\n
EDS etldev1 ~ # vgcreate vg_dwstore \/dev\/sdc1
\n Volume group “vg_dwstore” successfully created<\/p>\n
EDS etldev1 ~ # vgs
\n VG #PV #LV #SN Attr VSize VFree
\n vg_dwstore 1 0 0 wz–n- 136.11g 136.11g
\n vg_etldev1 1 8 0 wz–n- 135.62g 124.00m
\n vg_etldev1_data 1 1 0 wz–n- 136.12g 0 <\/p>\n
EDS etldev1 ~ # lvcreate -L 136.11g -n lv_dwstore vg_dwstore
\n Rounding up size to full physical extent 136.11 GiB
\n Logical volume “lv_dwstore” created<\/p>\n
