Installs lvm2 package and ensures it stays upgraded.
There are three LWRPs in the LVM cookbook that can be used to perform operations with the Logical Volume Manager.
Manages LVM physical volumes.
:create- Creates a new physical volume. Default.
nameThe device to create the new physical volume on. Required, name parameter.
Manages LVM logical volumes
:create- Creates a new logical volume
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_groupblock (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.
dumpfield for the fstab entry.
passfield 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'
lvm_logical_volume 'home' do group 'vg00' size '25%VG' filesystem 'ext4' mount_point '/home' stripes 3 mirrors 2 end
Manages LVM volume groups.
:create- Creates a new volume group. Default.
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_volumedefinition. The logical volumes will be created in the order they are declared.
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
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.
