I'm trying to install XenAPINFS driver for the XCP(hypervisor)/Havana, but it's not working:

cinder getting error from XAPI, that's xapi log:

info|xen2|53787 INET X.X.X.X:80|SR.introduce R:eb1788fd7ae0|audit] ('trackid=9cf839d9639a04fb3243a0234264a930' 'LOCAL_SUPERUSER' 'root' 'ALLOWED' 'ERROR:INTERNAL_ERROR: [ Db_exn.Uniqueness_constraint_violation(\"SR\", \"uuid\", \"b6aa2c0a-9d7d-7d5a-6c0c-adb55f2c7b45\") ]' 'API' 'SR.introduce' (('uuid' '' 'b6aa2c0a-9d7d-7d5a-6c0c-adb55f2c7b45' 'OpaqueRef:1305beef-5848-852a-382b-09c34ce627bb') ('name_label' '<string/>' '' '') ('name_description' '<string/>' '' '')))

I'm not sure what I did wrong, had somebody else the same issue?

Actually one update: This is only for snapshoting of some volumes, volumes creating just fine and snapshots (sometimes) also fine, but most of the time, they are immediately in Error state (without possibility to remove(wont remove, Error-Deleting)

One more update: it's happening only when snapshot is calling with Forced=True and volume attached to the instance.

P.S. I have cinder-api and cinder-scheduler on the controller node and cinder-volume is started on the storage/compute node.
