Creating LVG's and LVs in Azure

I have a post install script to partition and then add disk to Volume groups then create volumes in Azure. The parted portion of the script works fine but I get an error attempting to create the volume groups. Any help would be appreciated.

Thanks,

Dave

  • name: Partition disk
    parted:
    device: “/dev/disk/azure/scsi1/lun{{ item.lun }}”
    name: 1
    number: 1
    label: gpt
    state: present
    with_items:
  • “{{ extra_disks }}”

when: item.lun is defined

  • name: “Make U01”
    lvg:
    pvs: “/dev/disk/azure/scsi1/lun{{ u01.lun }}-part1”
    vg: “vg_{{ u01.vg }}”

when: u01.vg != “None”

  • name: Make backups logical volume group
    lvg:
    pvs: “/dev/disk/azure/scsi1/lun{{ backups.lun }}-part1”
    vg: “vg_{{ backups.vg }}”
    when: backups.vg != “None”

The disk definition file looks like this:

extra_disks:

  • { size: 512, type: Premium_LRS, lun: 0, name: u01 }
  • { size: 8192, type: Premium_LRS, lun: 1, name: backups }

I get the following error when attempting to create the U01 vg.

FAILED! => {“msg”: “The task includes an option with an undefined variable. The error was: ‘u01’ is undefined\n\nThe error appears to be in ‘/etc/ansible/playbooks/configure_disk-dave.yml’: line 25, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: "Make U01"\n ^ here\n”}

Hi,

The message is pretty clear, you have no u01 variable defined in you vars file !

So when the line ’ when: u01.vg !=“None”’ evaluate it crashed because u01 is not known…

Don’t know exactly what you want to do, but I saw ASM, so think about Oracle… Not sure mixing asm disk and LVM is a very good idea

Why use LVM in Azure/AWS/VMware, when you can just expand the disk and grow the filesystem?

LVM seems like an unneeded layer.
