Thank you Dan, here's all information I have
Before posting, it's an evidence, I searched on my friend google, but
the only concrete solution I found was to change permission on /dev/nst0.
before : crw-rw---- 1 root tape 9, 128 2006-05-03 17:51 /dev/nst0
after : crw-rw---- 1 bacula tape 9, 128 2006-05-03 17:51 /dev/nst0
I found this solution dirty because at every reboot /dev/nst0 recover
root owner. but, it's true, this solution works.
So I was wondering if there were an elegant answer. like using sudo?
Do you think using sudo with something like that is pretty ?
# /etc/sudoers
Host_Alias MES_ORDIS = localhost
User_Alias MES_USERS = bacula
Cmnd_Alias MES_COMMANDES = /bin/mt
root ALL=(ALL) ALL
MES_USERS MES_ORDIS=(root)NOPASSWD:MES_COMMANDES
in fact it seems that this sudo config isn't sufficient : I have this
message 2 times :
1) at beginning of backup but I don't know which binary try to access
/dev/nst0
2) at ending of backup but I know : my after_backup_script do a mt
rewind and mt eject...
But you're right, my question was too short I didn't give you
anything. So :
--------------------------------------------------------------------------------
My configuration is :
- Dell poweredge 1850 / Certance Ultrium LTO2 (powervault 110T)
- Debian Sarge 3.1 stable with custom kernel 2.6.12.6
- bacula installation by apt-get (1.36)
--------------------------------------------------------------------------------
id bacula returns :
uid=108(bacula) gid=108(bacula) groupes=108(bacula),26(tape)
(why bacula can't do mt correctly??? he's in tape group??!!)
--------------------------------------------------------------------------------

What does it mean?
Does this Google search help? http://tinyurl.com/lyvps
Failing that, you need to show us the job output, tell us what OS
you're using, and the version of Bacula. It'll also help to know
what UID/GID each bacula daemon is using, and the permissions on st0.
