lvg/jinja issue

[Mikael Sandström]

Hi,

ansible --version 

ansible 2.1.0.0

  config file = /Users/miksan/.ansible.cfg

  configured module search path = Default w/o overrides

I've got this gist where I'm attempting to create a volumegroup with multiple devices.

If I just debug the output it looks ok, 

"msg": "vg=vgtest pvs=/dev/sdb1,/dev/sdc1,/dev/sdd1 "

and if I copy-paste the debug message and run that as-is, it works as intended and the volume group is created ( I removed parts of the -vvv output).

ansible hostfs -m lvg -a "vg=vgtest pvs=/dev/sdb1,/dev/sdc1,/dev/sdd1 state=present" -s -i ~miksan/Applications/vagrant/hostfs/inventory -vvv

hostfs1 | SUCCESS => {

    "changed": true,

    "invocation": {

        "module_args": {

            "force": false,

            "pesize": 4,

            "pvs": [

                "/dev/sdb1",

                "/dev/sdc1",

                "/dev/sdd1"

            ],

            "state": "present",

            "vg": "vgtest",

            "vg_options": ""

        },

        "module_name": "lvg"

    }

}

But if I run the playbook, it fails at the lvg step with the following error.

TASK [filesystem | Create vg] **************************************************

failed: [hostfs1] (item={u'vgname': u'vgtest', u'disk': [{u'device': u'/dev/sdb', u'pvname': u'/dev/sdb1'}, {u'device': u'/dev/sdc', u'pvname': u'/dev/sdc1'}, {u'device': u'/dev/sdd', u'pvname': u'/dev/sdd1'}], u'filesystem': [{u'mntp': u'/vgtest', u'fstype': u'ext4', u'lvname': u'lvtest'}]}) => {"failed": true, "item": {"disk": [{"device": "/dev/sdb", "pvname": "/dev/sdb1"}, {"device": "/dev/sdc", "pvname": "/dev/sdc1"}, {"device": "/dev/sdd", "pvname": "/dev/sdd1"}], "filesystem": [{"fstype": "ext4", "lvname": "lvtest", "mntp": "/vgtest"}], "vgname": "vgtest"}, "msg": "Device /dev/sdd1  not found."}

It doesn't matter if I just use 1 device as well, the result is the same.

So, I'm not sure if the jinja-part does something to the string that I can't see or if there is something else going on.

Any ideas?

regards

I seems to be a spaces at the end of /dev/sdd1

Try removing the space at the end of host_fs_layout_vgdisks under vars.

Yep - that did the trick. 

Thanks for the extra set of eyes!
