Freezer-agent cinder restore not working

[vivek shrivastava]

Hi team,

I am using Freezer-agent for restore Cinder storage but getting below Critical error during restoration .

Freezer-agent version 8.1.0

Centos - RHEL -openstack / storage -local

command - freezer-agent --action restore --cinder-vol-id 35fada73-f02b-47c0-88ff-4095f16c291a --storage local --container /home/stack/cinder-bkp --backup-name bootable_volume-bkp --mode cinder --log-file cinder-restore.log

Kindly re-test codecs.py

Error---File "/usr/lib64/python3.6/codecs.py",
data = self.bytebuffer + newdata TypeError: can't concat str to bytes.
