Hi Thorsten,
Did you reboot the box recently and did by any chance your devices get
reordered?
What does lsscsi -g show and does that correspond to your
bacula-sd.conf entries?
Best regards, Udo
Hi Udo,
yes, I regularily reboot the system for maintenance:
sudo lsscsi -g
[0:0:0:0] disk Areca ARC-1883-VOL#000 R001 /dev/sda /dev/sg0
[0:0:0:1] disk Areca ARC-1883-VOL#001 R001 /dev/sdb /dev/sg1
[0:0:0:2] disk Areca Data6 R001 /dev/sdc /dev/sg2
[0:0:0:4] disk Areca VOL_Data4 R001 /dev/sdd /dev/sg3
[0:0:16:0] process Areca RAID controller R001 - /dev/sg4
[1:0:0:0] enclosu ATTO VirtualSES 0001 - /dev/sg6
[1:0:1:0] tape IBM ULTRIUM-HH9 R3G1 /dev/st0 /dev/sg7
[1:0:1:1] mediumx BDT FlexStor II 6.21 /dev/sch0 /dev/sg8
That looks very susual and it worked in the last months with sg7
Now, just for the fun of it I used mtx -f /dev/sg8 status additionally
and got:
mtx: Request Sense: Long Report=yes

As this surprisingly looked more like a changer, despite the error
code=70, I changed the changer path in bacula-sd.conf to /dev//sg8
Then I ran a backup (catalogue to make it quick):
*And to my surprise - the backup worked again. *
Now, this is a big surprise. I would not check the devices if despite
many reboots (both, host and changer) all of a sudden the device is not
correct. To be honest, that would probably be something I would not have
looked into....
Thanks. You made my weekend.
Cheers
T
