Now that the device mapper is all happy (see this article), let’s install the LVM software. Grab the source from here. Extract, configure, compile, and install:
sv-1# tar -xzf LVM2.2.01.15.tgz
sv-1# cd LVM2.2.01.15
sv-1# ./configure --prefix=/usr
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking for gawk... gawk

Set up the partitions as type Linux LVM using fdisk:
Hex code (type L to list codes): 8e Changed system type of partition 4 to 8e (Linux LVM) Command (m for help): p Disk /dev/hda: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 62 497983+ 83 Linux /dev/hda2 63 124 498015 82 Linux swap /dev/hda3 125 1341 9775552+ 83 Linux /dev/hda4 1342 30401 233424450 8e Linux LVM Command (m for help):w . . . |
Run lvmdiskscan to see what disks are available:
sv-1# lvmdiskscan /dev/hda1 [ 486.31 MB] /dev/hda2 [ 486.34 MB] /dev/hda3 [ 9.32 GB] /dev/hda4 [ 222.61 GB] 0 disks 4 partitions 0 LVM physical volume whole disks 0 LVM physical volumes |
Create a physical volume and volume group:
sv-1# pvcreate /dev/hda4 Physical volume "/dev/hda4" successfully created sv-1# vgcreate volgroup /dev/hda4 Volume group "volgroup" successfully created sv-1# vgdisplay --- Volume group --- VG Name volgroup System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 1 VG Access read/write VG Status resizable MAX LV 0 Cur LV 0 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 222.61 GB PE Size 4.00 MB Total PE 56988 Alloc PE / Size 0 / 0 Free PE / Size 56988 / 222.61 GB VG UUID qauL7L-rO53-5EBU-6jgj-49CN-xJwL-sun5C0 |
Create a logical volume:
sv-1# lvcreate -L200G -nlogicalvol volgroup Rounding up size to full physical extent 200 GB Logical volume "logicalvol" created |
This is how the block device looks:
sv-1# ls -l /dev/volgroup/logicalvol lrwxrwxrwx 1 root root 31 Jun 24 17:56 /dev/volgroup/logicalvol -> /dev/mapper/volgroup-logicalvol sv-1# |
