I have a problem while I try to create the new volume:

Connecting to Director localhost:9101

     Device "FileStorage" requested by DIR could not be opened or does not exist.

Do not forget to mount the drive!!!

I'm really not sure what is wrong. The dir and sub-dirs bacula user and tape group is owner and for test purpose I've gave full access to the dir tree:

drwxrwxrwx  4 bacula tape       4096 lut  4 14:10 bacula_backup

root@rpi1backup:/etc/bacula# ls -al /media/backup/bacula_backup/
razem 16
drwxrwxrwx  4 bacula tape 4096 lut  4 14:10 .
dr-x------ 11 pi     pi   4096 lut  4 12:36 ..
drwxrwxrwx  2 bacula tape 4096 lut  4 14:10 bootstrap
drwxrwxrwx  2 bacula tape 4096 lut  4 14:05 restores

the Device part of bacula-sd.conf looks like this:

Device {
  Name = FileStorage
  Media Type = File
  Archive Device =  /media/backup/bacula_backup/
  LabelMedia = yes;                   # lets Bacula label unlabeled media
  Random Access = Yes;
  AutomaticMount = yes;               # when device opened, read it
  RemovableMedia = no;
  AlwaysOpen = no;
}

What is wrong?
