[Xen-users] LVM access problem

["Novaes, Reynaldo" <reynaldo.novaes@xxxxxx>]

I'm using LVM to create CoW disk on my Xen box. The problem is that the VMs are 
not able to access the LVM devices after running for some hours. 

I have the folowing LVM configurations (result of a lvscan):
  ACTIVE   Original '/dev/xen-vg/RH-EL.WS.4' [4.00 GB] inherit
  ACTIVE   Snapshot '/dev/xen-vg/RH-EL.WS.4-01' [200.00 MB] inherit
  ACTIVE   Snapshot '/dev/xen-vg/RH-EL.WS.4-02' [200.00 MB] inherit
  ACTIVE   Snapshot '/dev/xen-vg/RH-EL.WS.4-03' [200.00 MB] inherit
  ACTIVE            '/dev/xen-vg/SWAP01' [512.00 MB] inherit
  ACTIVE            '/dev/xen-vg/SWAP02' [512.00 MB] inherit
  ACTIVE            '/dev/xen-vg/SWAP03' [512.00 MB] inherit

Each machine has a separate SWAP device and uses a snapshot device (listed 
above). The Original volume is not used.

In xen configuration file the disks definition are:
disk = ['phy:xen-vg/RH-EL.WS.4-%02d,sda1,w' % vmid,
        'phy:xen-vg/SWAP%02d,sda2,w' % vmid]

Did anybody see this problem before? Is there any solution for it?

Regards,
Reynaldo
