[SOLVED] Can't start new VM with proxmox 4.3 !

[hregis]

Hi,

after upgrade proxmox with the latest 4.3, I have an error message when starting a new VM :
(the VMs created before the update works fine)

kvm: -drive file=/dev/drbd/by-res/vm-502-disk-1/0,if=none,id=drive-virtio0,cache=writethrough,format=raw,aio=threads,detect-zeroes=on: Could not open '/dev/drbd/by-res/vm-502-disk-1/0': No such file or directory

the volume and resource "vm-502-disk-1" is ok, but it does not appear with "drbdsetup show", and it does not appear with "drbd-overview" !!

what is the problem please ?

thanks

Ok I found it! The update crashed the configuration of drbdmanage.

replace:
storage-plugin = drbdmanage.storage.lvm_thinlv.LvmThinLv

by:
storage-plugin = drbdmanage.storage.lvm.Lvm

• Modify config with
  
  

  drbdmanage modify-config

• 
  
• Choose a storage plugin, and insert it in the config like
  
  

  storage-plugin = drbdmanage.storage.lvm.Lvm
