Hi.
I am searching for hours, but I am not able to figure out, why I get this
error...
Yes, I know, it must be a permission setting but I am too stupid to find it even
after years on linux.

This is my setup:
Device {
  Name = nas2016
  Media Type = File
  Archive Device = /nas2016
  LabelMedia = yes;                   # lets Bacula label unlabeled media
  Random Access = Yes;
  # AutomaticMount = no;               # when device opened, read it
  # RemovableMedia = no;
  AutomaticMount = yes;
  RemovableMedia = yes;
  AlwaysOpen = no;
  Maximum Volume Size = 295GB;
  Requires Mount = no;
  Mount Point = /nas2016
#
#  nicht notwendig, NAS wird per /etc/fstab beim Booten gemountet.
#
#  Mount Command = "/bin/mount /nas01_backup";
#  Unmount Command = "/bin/umount /nas01_backup";
}

The Mount Point looks like that:
Notice, it is 777...
drwxrwxrwx.   3 nobody nobody  4096 19. Mai 16:14 nas2016

I am able to touch a file there using:
sudo -u bacula touch /nas2016/test
I can even see (when using vi instead of touch) the contents of the file using
the nas gui.

The nas is mounted via fstab and looks like this:
cat /proc/mounts | grep nas
nas2016.privat.i-concept.de:/volume1/backups /nas2016 nfs4
rw,relatime,vers=4.0,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.50,local_lock=none,addr=192.168.1.15
0 0

Storage {                             # definition of myself
  Name = backnix05-sd
  SDPort = 9103                  # Director's port
  WorkingDirectory = "/var/spool/bacula"
  Pid Directory = "/var/run"
  Maximum Concurrent Jobs = 5
}

I am on CentOS 7, running backnix05-dir Version: 5.2.13 (19 February 2013)

The error is triggered when doing this:

*label

Label command failed for Volume bkp-nas-0422.
Do not forget to mount the drive!!!

Bacula tries to open the file, but with an ls -l I am not able to see the file
/nas2016/bkp-nas-0422 either. Is it not there, because bacula is not able to
produce and is this caused by the permission error? Or is the error triggered at
a earlier point?

Just in case: Yes, sd and dir are running as user bacula.

ps axf | grep bacula
 1305 ?        Ssl    0:00 /usr/sbin/bacula-dir -f -c
/etc/bacula/bacula-dir.conf -u bacula -g bacula
 1315 ?        Ssl    0:00 /usr/sbin/bacula-fd -f -c /etc/bacula/bacula-fd.conf
-u root -g root

 2963 pts/1    S+     0:00  |       \_ vi /etc/bacula/bacula-sd.conf
 1336 ?        Ssl    0:00 /usr/sbin/bacula-sd -f -c /etc/bacula/bacula-sd.conf
-u bacula -g tape

Please help, my backups are not running.

Thanks.
Stefan
