Task:
Create a logical volume via Ansible/AAP.
Notes:
- The lvol module is in the community.general collection.
- The active parameter is true, active and visible, by default, to the host.
- The resizefs expansion is supported for ext3, ext4, XFS, and a couple others.
- If shrinking a LV, ensure there is enough free space, and include the force parameter.
- Use thinpool paramter if using a thin provisioned volue.
- vg: volume group to use
- lv: logical volume name of the new LV to create
- size: the disk space, in MBs, by default, to give the new LV
- pvs: the physical disk volume(s) to span the LV across
Examples:
Code snippet 1:
- name: Create a logical volume of 8 GB within the volume group apps for the Domino app
community.general.lvol:
vg: apps
lv: notesdata
size: 8192
Code snippet 2:
- name: Create a logical volume using all space within the volume group apps for the Domino app
community.general.lvol:
vg: apps
lv: notesdata
size: 100%FREE
Code snippet 3:
- name: Extend an existing logical volume notesdata to consume all remaining space in a volume group
vg: apps
lv: notesdata
size: +100%FREE
Code snippet 4:
- name: Create a logic volume of 16 GB using physical disks/volumes
vg: apps
lv: notesdata
size: 16384
pvs:
- /dev/sdb
- /dev/sdc
Code snippet 5:
- name: Reduce an existing logic volume of 16 GB to 8 GB
vg: apps
lv: notesdata
size: 8192
force: true
Code snippet 6:
- name: Remove a notesdata logical volume from a volume group
vg: apps
lv: notesdata
state: absent
force: true
Code snippet 7:
