[one-users] how to use lvm datastore for virtual machine disks

[Denis J. Cirulis]

Hi Marlok,
maybe I'm giving too few details of the problem:

lvm datastore:
[oneadmin at master ~]$ onedatastore show 104
DATASTORE 104 INFORMATION

ID             : 104
NAME           : production-ds
USER           : oneadmin
GROUP          : oneadmin
CLUSTER        : production
TYPE           : IMAGE
DS_MAD         : lvm
TM_MAD         : lvm
BASE PATH      : /var/lib/one/datastores/104
DISK_TYPE      : BLOCK

PERMISSIONS

OWNER          : um-
GROUP          : u--
OTHER          : ---

DATASTORE TEMPLATE

CLUSTER="production"
DS_MAD="lvm"
HOST="compute01"
TM_MAD="lvm"
VG_NAME="prod-vm"

IMAGES
[oneadmin at master ~]$

compute01 is a kvm node where lvm operations will be held, cause backing
storage for that is fibre channel lun, which then will be accessible on all
compute nodes.

Then, I imported ttylinux image to production-ds datastore and all I got in
Images section of the Sunstone UI is :
   Tue May 28 17:19:53 2013 : Error copying image in the datastore: Error
registering compute01:/dev/prod-vm/lv-one-7
User oneadmin is in sudoers and is able to launch any lv* command through
sudo.
