Description

Installs lvm2 package and ensures it stays upgraded.

Requirements

• Debian/Ubuntu
• RHEL/CentOS

Resources/Providers

There are three LWRPs in the LVM cookbook that can be used to perform operations with the Logical Volume Manager.

lvm_physical_volume

Manages LVM physical volumes.

Actions

• :create - Creates a new physical volume. Default.

Attribute Parameters

• name The device to create the new physical volume on. Required, name parameter.

Example

lvm_physical_volume '/dev/sda'

lvm_logical_volume

Manages LVM logical volumes

Actions

• :create - Creates a new logical volume

Attribute Parameters

• name - The name of the logical volume. Required, name parameter.
• group - The volume group in which to create the new volume. Required unless the volume is declared inside of an lvm_volume_group block (see below).
• size - The size of the volume. This can be any of the size specifications supported by LVM—SI bytes (e.g. 10G), physical extents, or percentages of all the extents in the volume group, all the free extents, or of the physical volumes assigned to the volume.
• filesystem - The filesystem to format the volume as. The appropriate tools must be installed for the filesystem.
• mount_point - Either a string containing the path to the mount point, or a Hash containing the following keys:
  • location - the directory to mount the volume on. Required.
  • options - the mount options for the volume.
  • dump - the dump field for the fstab entry.
  • pass - the pass field for the fstab entry.
• physical_volumes - An array of physical volumes that the volume will be restricted to.
• stripes - the number of stripes for the volume.
• stripe_size - the number of kilobytes per stripe segment. Must be a power of 2 less than or equal to the physical extent size for the volume group.
• mirrors - the number of mirrors for the volume.
• contiguous - whether or not volume should use the contiguous allocation policy. Default is non-contiguous.
• readahead - the readahead sector count for the volume. Can be a value between 2 and 120, 'auto', or 'none'

Example

lvm_logical_volume 'home' do
    group 'vg00'
    size '25%VG'
    filesystem 'ext4'
    mount_point '/home'
    stripes 3
    mirrors 2
end

`lvm_volume_group` ------------------

Manages LVM volume groups.

Actions

• :create - Creates a new volume group. Default.

Attribute Parameters

• name - The name of the volume group. Required, name parameter.
• physical_volumes - A device or list of devices to use as physical volumes. If they haven't already been initialized as physical volumes, they will be initialized automatically. Required.
• physical_extent_size - The physical extent size for the volume group.
• logical_volume - A shortcut for creating a new lvm_logical_volume definition. The logical volumes will be created in the order they are declared.

Example

lvm_volume_group 'vg00' do
    physical_volumes [ /dev/sda, /dev/sdb, /dev/sdc ]
    logical_volume 'logs' do
        size '1G'
        filesystem 'xfs'
        mount_point :location => '/var/log', :options => 'noatime,nodiratime'
        stripes 3
    end
    logical_volume 'home' do
        size '25%VG'
        filesystem 'ext4'
        mount_point '/home'
        stripes 3
        mirrors 2
    end
end

Usage

Make sure the lvm package is always up to date with this recipe. Put it in a base role that gets applied to all nodes.
