Shared Image storage with Intel Modular Server

[mbraun]

Hi all,

i'm running a Intel Modular Server with a couple of compute nodes and some disks. We got the IMS as Proxmox host since it was advertised at the documentation. I'm having trouble using shared LVM storage for my disk images. Here's what i did:

1. Created a storage pool at IMS
2. Created a 800GB virtual disk
3. Assigned that disk to all compute nodes
4. Created a partition table, a physical LVM volume and volume group
5. Added the LVM group to Proxmox 2.0 at one server and ticked the "shared" checkbox

Now i see the volume group at both machines, but only the machine where i created the pv and vg shows its actual content. The other machine doesn't even show the partition i created.

Machine 1:

cat /proc/partitions
   8       32  838860800 sdc
   8       33  838858041 sdc1

All other machines:

cat /proc/partitions
   8       32  838860800 sdc

Did anybody face a similar issue and may have a hint in what direction to research further?

Thanks!
Martin
