Really thanks Andrea.. That is a side of Linux I never investigate from my side and I guess I'll have a good time digging inside.

If your system supports udev, you can write your own rule. This is for
a debian etch system.
/etc/udev/rules.d/010-local.rules
SUBSYSTEM=="scsi_generic", SYSFS{model}=="T40A",
SYMLINK+="NEC-T40A", GROUP="tape", MODE="0660"
KERNEL=="st*", GROUP="tape", MODE="0660"
KERNEL=="nst*", GROUP="tape", MODE="0660
VU0EM005:~# ls -l /dev/NEC-T40A
lrwxrwxrwx 1 root root 4 2007-02-09 15:18 /dev/NEC-T40A -> sg11
VU0EM005:~# ls -l /dev/sg11
crw-rw 1 root tape 21, 11 2007-02-09 15:18 /dev/sg11
VU0EM005:~# ls -l /dev/nst*
crw-rw 1 root tape 9, 128 2007-02-09 15:18 /dev/nst0
...
You can get the necessary information with udevinfo.
udevinfo -a -p $(udevinfo -q path -n /dev/$YOURDEVICE)

I suppose you're using a recent (>2) version of fedora, so your system should be running udev. If that's the case, you just need to tell udev which owner/group/permissions you want that device node to be created with. Create a file named "10-tape.rules" in /etc/udev/rules.d with the following line in it: KERNEL=="nst0", OWNER="foo", GROUP="bar", MODE="0660" If you don't need to set the owner or group simply leave out the corresponding section. Taking a look at the udev documentation on rule writing might also be a good idea, since there is much more you can do with it. Andrea - Take Surveys. Earn Cash.

Re: [Bacula-users] Cannot label tape from bconsole
I agree and your position is true. Can you tell me what method you have in mind for changing permissions? A shell line inside /etc/init.d/bacula-sd.conf (I use Fedora) with the chmod previously said or a different command?

Re: [Bacula-users] Cannot label tape from bconsole
Changed permission of /dev/nst0* into 660 and works correctly! I suggest
to add the "chmod " line into the Brief tutorial while testing not on
file but on real tape.
Thanks alot Adam!

Check permissions on /dev/nst0.

[Bacula-users] Cannot label tape from bconsole
While setting up Bacula and following "Brief Tutorial", I see a strange
problem: after the command "run" asking me for labelling the tape, I
give the command "label", and bconsole gets lock for some 2 minutes,
than says:
3910 Unable to open device "DAT72" (/dev/nst0): ERR=dev.c:424 Unable to
open device "DAT72" (/dev/nst0): ERR=Permission denied
The most strange thing is that if I use btape /dev/nst0 and issue a
command "label", it works correctly and the "read" command says the tape
has been correctly labelled.
The Linux Box is a FC4.
bacula-sd.conf file about device is:
Device {
Name = DAT72
Media Type = DSS-3
Device Type = Tape
Archive Device = /dev/nst0
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
Label Media = yes;
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}
and in the bacula-dir.conf:
Storage {
Name = Tape
Address = backupserver.pippo.local #existing address resolved
SDPort = 9103
Password = ""
Device = DAT72
Media Type = DSS-3
}
Any help?
Thanks
