Hello,

I've a problem to adding lvm storage i follow this guide http://pve.proxmox.com/wiki/Storage_Model and i did all command successfully.

Code:

# pvdisplay  --- Physical volume ---
  PV Name               /dev/sda4
  VG Name               imagen
  PV Size               905.32 GiB / not usable 4.00 MiB
  Allocatable           yes
  PE Size               4.00 MiB
  Total PE              231760
  Free PE               231760
  Allocated PE          0
  PV UUID               LeY2lS-B1Ey-LZSP-lCQj-wknb-3AEe-FCceFh

Code:

# vgdisplay  --- Volume group ---
  VG Name               imagen
  System ID
  Format                lvm2

  VG UUID               37v8NN-6cL7-1tun-apm4-UNSx-wMZP-Pc7dRI

In proxmox gui web also show the information:

The problem come where when i try to add vm no show the lvm storage

Hi,
looks ok! But shows also that you don't have an standard-installation. Perhaps there is an pve-packages missing?

Are all packages installed?

Hi,
no - that's not the same problem. In your cast there isn't an entry for the lvm-storage.

See Datacenter -> Storage -> Add LVM -> Existing volume groups -> named and select your pve2

jorge_jvm · May 7, 2014

Hi, thanks for answer and for your time.

that's really the problem does not appear pve2 not know why, any ideas?

Hi,
you added the VG on pmx2 but your web-gui is from pmx1. pmx1 don't see the new VG!

Udo

jorge_jvm · May 7, 2014

hello, thanks for reply, is correct, but only in the cluster in datacenter is where I may not create lvm nodes, am I right? only shows me a local only.

I still do not understand how it works whether the cluster with Proxmox, since it is more logical to show me the two datacenters and not just one, but also creates the Proxmox not?

before finding this thread I posted here.

https://forum.proxmox.com/threads/18455-Add-HDD-in-node-proxmox?p=94413#post94413

best regards

udo · May 7, 2014

Hi,
simply login on the right node: https://pmx2:8006 and define on Datacenter -> storage the lvmstorage. Not shared and only accessible for node pmx2.
Thats all.

Udo

jorge_jvm · May 7, 2014

hello, I thanks deeras much your time, right, works as you mention, what happens is that being in a cluster, I thought that all these functions are managed from a single page and not entering into each individual, there is way to manage all nodes from a single console?

best regards

jorge_jvm · May 8, 2014

hello again, I've done what you mention as lvm and I can see, but only gives permission to post images, I can not install a system on that disk? I followed another statute and assume that the amount and add it as a disk directory, but this directory I see in the two (pmx1 and pmx2) with different capasidades, what is the correct way to do this I want to do?

Hi,
new problem, new thread please.

In short - for uses on both hosts, you need "shared" storage. And for backup/templates/CTs you need an filesystem - e.g. NFS.
For kvm only drbd or ceph is an good solution.
