Still backup errors with backup of iSCSI machines

[bemar]

Hello, I have the following problem with snapshot backup of running KVM machines stored on iSCSI - Destination NFS share:

 INFO: starting new backup job: vzdump 102 --remove 0 --mode snapshot --compress lzo --storage NFSData --node vmhost1
INFO: Starting Backup of VM 102 (qemu)
INFO: status = running
INFO: backup mode: snapshot
INFO: ionice priority: 7
INFO:   Logical volume "vzsnap-vmhost1-0" already exists in volume group "lvm.iscsi.lun0"
ERROR:  Backup of VM 102 failed - command 'lvcreate --size 1024M --snapshot  --name 'vzsnap-vmhost1-0' '/dev/lvm.iscsi.lun0/vm-102-disk-1'' failed:  exit code 5
INFO: Backup job finished with errors
TASK ERROR: job errors

Any ideas?

Thank you and best regards

Ben

Output of pvdisplay:

90% of the iscsi target is free

Why does the backup wants to create a logical volume on the iscsi device when I've defined the nfs as target?
