Description

This puppet profile installs LVM software and configures LVs on a node.

It sets NCSA-defaults for certain configs.

It generally assumes you will set up PVs and VGs manually but they could be configured with the underlying lvm Puppet module.

Setup

Include profile_lvm in a puppet profile file:

include ::profile_lvm

Usage

Define LVs (logical volumes) using the lvs param, which takes raw data in the format that the lvm module expects. For example:

profile_lvm::lvs:
  "slurm":
    mountpath: "/slurm"
    size: "100G"
    size_is_minsize: true
    volume_group: "data"

Optionally define non-standard required packages or a custom default filesystem type:

profile_lvm::default_fs_type: "ext4"
profile_lvm::required_pkgs:
  - "lvm2"
  - "lvm2-devel"

Optionally define bindmounts from LVs (or sub-directories contained in LVs):

profile_lvm::bindmounts::map:
  "/var/log/slurm":
    src_lv: "slurm"
    src_path: "/slurm/log"
  "/var/spool/slurmctld.state":
    src_lv: "slurm"
    src_path: "/slurm/slurmctld.state"
