RAIT problem

[ipv4]

Hi all,
I use the guide to set up RAIT ([url]http://wiki.zmanda.com/index.php/Rait[/url]) using tape and vtapes.

When i try to label slot 1 amanda show an error:

#amlabel daily daily-01 slot 1
labeling tape in slot 1 (rait:{file:/amanda/vtapes/daily/slot1,tape:/dev/nst0}):
Reading label...
RAIT array {file:/amanda/vtapes/daily/slot1,tape:/dev/nst0} isolated device /dev/nst0
RAIT array {file:/amanda/vtapes/daily/slot1,tape:/dev/nst0} DEGRADED
File /dev/nst0 is not a tape device
Reading the tape label failed:
Error was Device error.

tape not labeled

What's wrong?

Here are the amlabel log file

1231948968.278970: amlabel: pid 18039 ruid 505 euid 505: start at Wed Jan 14 17:02:48 2009

And chg-multi-mirror.conf

slot 4 rait:{file:/amanda/vtapes/daily/slot4,tape:/dev/nst0}
slot 5 rait:{file:/amanda/vtapes/daily/slot5,tape:/dev/nst0}


If i use only the tape driver in a single configuration i don't have any problem so i post the changer.conf:

firstslot=2
lastslot=14
driveslot=0
havereader=1
offline_before_unload=1
initial_poll_delay=30

In amanda.conf should not add the parameter tapetype AIT-2?(there's only HARDDISK)

Please help.

Thank you

If /dev/nst0 is indeed a tape device and can be accessed by the Amanda user, I'm not sure.

Is a log created by the chg-multi script in /var/log/amanda/server/ with any more clues?

For tapetype, I suppose you should use one that correlates to the physcial tape.

The error message is pretty clear (though admittedly buried mid-line):

ioctl(MTIOCTOP/MTNOP) failed: No medium found

was there a tape in the drive? Was the drive ready? Some drives can take quite a while to come online.
