Hello

I was using some scripts to create virtual machines. After latest updates on pve-storage packages qm create returns error when creating machines with more than one virtual disk on local-lvm storage.

Code: 
# /usr/sbin/qm create 101 --name test --ostype l26 --cpu cputype=host --sockets 4 --cores 1 --numa no --memory 4096 --scsihw virtio-scsi-pci --scsi0 local-lvm:20,discard=on --scsi1 local-lvm:1,backup=no,replicate=no,discard=on --net0 virtio,bridge=vmbr0 --ide2 NFS-ISO:iso/debian-9.5.0-amd64-netinst.iso,media=cdrom --boot d --onboot yes
  Using default stripesize 64.00 KiB.
  Logical volume "vm-101-disk-0" created.
Use of uninitialized value $fmt in string ne at /usr/share/perl5/PVE/Storage/LvmThinPlugin.pm line 87.
Use of uninitialized value $fmt in concatenation (.) or string at /usr/share/perl5/PVE/Storage/LvmThinPlugin.pm line 87.
  Logical volume "vm-101-disk-0" successfully removed
unable to create VM 101 - unsupported format '' at /usr/share/perl5/PVE/Storage/LvmThinPlugin.pm line 87.

Creating a VM with a single disk works fine:
Code: 
# /usr/sbin/qm create 101 --name test --ostype l26 --cpu cputype=host --sockets 4 --cores 1 --numa no --memory 4096 --scsihw virtio-scsi-pci --scsi0 local-lvm:20,discard=on --net0 virtio,bridge=vmbr0 --ide2 NFS-ISO:iso/debian-9.5.0-amd64-netinst.iso,media=cdrom --boot d --onboot yes
  Using default stripesize 64.00 KiB.
  Logical volume "vm-101-disk-0" created.

Before the pve-storage package update everything was fine.
Proxmox 5, packages up-to-date.

Makes sense (assuming recover = restore) - there the disks also get created simultaneously - resulting in the same bug.

Glad to hear the issue is resolved!
 
Same bug occur on vm cloning with multi disk.
