Hello.
I cannot backup over 2 volumes simultaneously.
Errors:

greenlet.error: cannot switch to a different thread
I tried to change but it wont work:
- connection time in mariadb to 120
- backup worker in cinder.conf to 2
My env:
Kolla Ansible Yoga on Ubuntu 20.04
My Cinder backend is SAN powerstore5000T
Thank you. |
