Re: [Bacula-users] Error talking to remote storage daemon

Hi steve,

It seems we have a configuration issue. It is not a good idea to have symlinks to sg devices. They can change after a server reboot.

**************

From the /dev directory on odin:
lrwxrwxrwx 1 root root 3 Jun 5 17:42 /dev/autochanger1 -> sg3
crw-rw---- 1 root tape 21, 3 Jun 1 15:01 /dev/sg3

**************

This can be very probably causing this issue with the label command. But I can't confirm this because I have never tried this.

It is better to use the /dev/tape/by-id names and even better to create udev rules based on the tape library specific charactheristics such as serial number.

A "ls -lR /dev/tape" and "lsscsi -g" will help you.

Then you should chage:

Changer Device = /dev/autochanger1 with the by-id name for mediumx

And

Archive Device = /dev/nst0 with the by-id name for the tape drive (remember to use here the one that ends with -nst).

I noticed you have data spool configured. With an LTO6 It is very probably that you will slow down backups performance, unless you have clients with poor network performance.

Hope this helps you.

Best regards,

Ana

OK, I've got my tape drive working (thanks Ana!) but I'm having trouble connecting to the autochanger it's in using the director. This is the first time I've tried having a storage daemon on a different machine than the director. The director is a slightly lower version (7.4.3 on Debian Jessie using backports) than the storage daemon (7.4.4 on stretch) but I had understood that those versions were close enough to work.

So I'm hoping this is another configuration issue.

Right now what I'm trying to do is label all the tapes in the new library.

When I try to access the new storage from the director, it is able to get a listing of all the tapes, but it fails when it tries to actually do the labeling. I get a "3999 Device not found or could not be opened" error. These errors show up quickly, there is no delay as it tries each slot, so it's obviously not getting far enough to try. But it *is* obviously connecting to the remote storage, otherwise it wouldn't be able to obtain the slot list.

What am I missing?
