Title:
LXC termination fails using LVM for root
Status in OpenStack Compute (Nova):
Triaged
Bug description:
Hello,
Terminating an instance running on LXC with LVM as instance root
storage fails with an exception.
The LVM volume is wiped using dd, but it is not disconnected from
qemu-nbd before the LVM volume gets removed.
The instance in itself on the compute node is stopped but still marked as
Active, Deleting in nova. qemu-nbd is sill running.
After first failure, disconnecting the qemu-nbd process manually and
relaunching the instance termination works
Log file in debug attached
Environment:
