disk-init
disk-init
This role adds complete disks in to LVM Groups. It is aimed to be idempotent and just adds new disks. It currently does not remove disks from a diskgroup nor cleans up disks that do have a valid LVM signature on the disk (created by pvcreate)
Requirements
It is tested on RHEL EL7, but should work on Centos 6,7, EL7 and Fedora. The system must be properly subscribed to install the required packages for diskmanagement (gdisk, sg3_utils, lvm2)
Role Variables
To define the disk setup of s system the follwowing variables need to be set in your playbook:
disks:
<devicepath1> : <volumegroup>
<devicepath2> : <volumegroup>
...
logvols:
<logical_volume_name1>:
size: <size>
vol: <volumegroup>
mountpoint: <mountpoint>
pvs: <devicepath> (optional, if you want to place vol explicitly)
fstype: xfs (optional, defaults to xfs)
opts: -b 4096 (optional paramters for mounting)
<logical_volume_name2>:
size: <size>
vol: <volumegroup>
mountpoint: <mountpoint>
pvs: <devicepath> (optional, if you want to place vol explicitly)
fstype: xfs (optional, defaults to xfs)
opts: -b 4096 (optional paramters for mounting)
....
