lvm-management

Manage lvm volume groups and volumes with their respective fstypes and mountpoints

Requirements

None (yet...)

Role Variables

lvm_management_default_fstype: ext4

Default filesystem to use to format logical volumes unless otherwise stated

lvm_management_default_fstab_dump: 0

Default value for dump field (5th) in fstab. See man fstab

lvm_management_default_fstab_passno: 0

Default value for passno field (6th) in fstab. See man fstab

lvm_management_default_vg: vg01

Default volume group for logical volume creation unless otherwise stated

lvm_management_vgs: []
# Example vg definition
# - name: vg01
#   pvs: /dev/sdb,/dev/sdc

List of logical volumes groups to create. Empty by default. Each VG in the list must define:

• name (required): the name of the Volume Group
• pvs (required): coma separated list of physical volumes to use. PVS will be automatically initialized for use with lvm (pvcreate) when needed.

# List of logical volumes to be created
# List higest mountpoints firts (i.e. /mount before /mnt/sub/mount)
lvm_management_lvs: []
# Example lv definition
# - name: lv_01
#   size: 1G
#   mountpoint: /mnt/volume1
#   vg: vg_02
#   fstype: xfs
#   fstab_dump: 1
#   fstab_passno: 2
#   fstab_opts: noauto

List of logical volumes to create. Each lv in the list defines:

• name (required): Name of the logical volume
• size (required): The size of the logical volume (see -L option of lvcreate). Resizing volumes has not been tested yet.
• mountpoint (required): The path to the mount point. It will be created if it does not exist. If you have submounts, make sure to list the highest mountpoints first in the list (i.e. /rootmount before /rootmount/submount).
• fstype (optional): Filesystem to use. Volume will be formated when needed. defaults to lvm_management_default_fstype. Resizing and/or changing fstype has not been tested yet.
• fstab_dump (optionnal): Value of dump field (5th) in fstab. See man fstab. Will default to lvm_management_default_fstab_dump
• fstab_passno (optionnal): Value of passno field (6th) in fstab. See man fstab. Will default to lvm_management_default_fstab_passno
• fstab_opts (optionnal): Value of mount option field (4th) in fstab. See man fstab. Will default to "defaults".

Dependencies

• Must be ran on a physical machine or a VM
• OS with lvm support
