i am having trouble understanding how to config different nfs shares on different nfs servers, one for cinder and ANOTHER one for use for cinder-backup, this is my files:

(already check both nfs export are reachable and works fine in rw inside openstack)

(kolla latest version on ubuntu 22 hosts, all-in-one-deploy)

[globals.yaml]

...

enable_cinder: "yes"
enable_cinder_backend_nfs: "yes"
enable_cinder_backup: "yes"
cinder_backup_driver: "nfs"
cinder_backup_share: "192.168.100.100:/exports/backup"
cinder_backup_mount_options_nfs: "vers=3"

[config/nfs_shares]

192.168.100.100:/exports/backup

192.168.200.200:/exports/volumes

thank you.
