Problem creating VM

[Jonathan Bayer]

Hi,

Trying to create a new VM using the following command:

[root@node1 ~]#bash a.sh
Fri Sep 28 11:50:16 2012 * creating instance disks...
Fri Sep 28 11:50:17 2012 - WARNING: Device creation failed, reverting...
Failure: command execution error:
Can't create block device
<LogicalVolume(/dev/xenvg/f125a43a-4e24-40ed-9a07-2d5998f3f3f7.disk0_meta,
not visible, size=128m)> on node node2.achieve3000.com for instance
ins1.achieve3000.com: Can't create block device: Can't compute PV info
for vg xenvg


and here is the output form pvs, lvs and vgs:

[root@node1 ~]#pvs
PV VG Fmt Attr PSize PFree
/dev/sda6 LvmVms lvm2 a-- 1.05t 1.05t
[root@node1 ~]#lvs
[root@node1 ~]#vgs

LvmVms 1 0 0 wz--n- 1.05t 1.05t


[root@node2 ~]#pvs

/dev/sda6 LvmVms lvm2 a-- 1.05t 1.05t
[root@node2 ~]#lvs
[root@node2 ~]#vgs
VG #PV #LV #SN Attr VSize VFree
LvmVms 1 0 0 wz--n- 1.05t 1.05t



Any ideas as to what's wrong?


Thanks in advance.

Sorry, forgot to give the environment:

RHEL 6.3
48 gig
Set up to use KVM

The cluster is looking for a VG called xenvg...

...but no PVs in that VG. Either change the cluster configuration or
change your VG.
