Re: [Bacula-users] How to use Bscan - Segmentation Fault

Kern Sibbald Thu, 12 May 2016 12:31:30 -0700

Something is clearly broken here. dcr is a pointer so it should never be zero as it is in your case.

There are two things you can do:

1. Execute: thread apply all bt
rather than just a bt command.

2. Run bscan with a debug level of 200 and capture the output.

Best regards,
Kern

Hello Kern

If I have volumes written with bacula 5.2.x I can't use bscan, bls or bextract of bacula 7.x in a new installation?

Because I can have volumes with an long retention and during this time I will upgrade bacula.

Waww...

This is a fedora 23,

I'll try now.

Thank you

Carlo, are you using a Linux system here with SELinux enabled and enforcing? If so, would you consider disabling it temporarily for a test run?

Now it's at 7% of 530Gb of volumes.. we will see!

Sorry, Carlo,

Didn't notice the backlash that can also be used to "escape" the pipe.
Anyway ai think there is a very small possibility that bscan is messed by dashes (-) in you volume names or by another syntax problem that is not being acused.

Hi,

can you explain better what you want to say?

I'm reading the Bacula's document (The Leading Open Source Backup Solution - Utility Programs - August 14, 2015)
and find
    bscan -c bacula-sd.conf -v -V Vol001\|Vol002 /dev/nst0

so I think that this is not the problem.

Thank you

Carlo: scape the list of volume names with quotes you must. Pipe is a special shell character.

What does it means?

Hello, Carlo: what is the version of this bscan? How do you installed Bacula? What is the exact bscan command are you using to fetch the error? Can you post the error output?

Btw: Ana is right. Both MySQL and Postgresql have also replication features that might perform what you want with lesser computational effort and storage stress.

Regards,

Thanks

Hi all,

I'm trying to create a secondary site using the bscan feature to recreate the Catalog.

I use this command:

bscan -V V-Daily-0005 -d1 -dt -m -v -s -S -c /etc/bacula/bacula-sd.conf /data/bacula/data/ >> /var/log/bacula_import 2>&1

When I user little volumes I don't have any problem running a test

bscan -V V-Daily-0005 -v -c /etc/bacula/bacula-sd.conf /data/bacula/data/ >> /var/log/bacula_import 1>&2

I have the output:

Records would have been added or updated in the catalog:
     1 Media
     1 Pool
    23 Job

If I use a big Volume (700Gb) I receive

Errore di segmentazione (core dump creato)

Error segmentation fault (core dump created)

Why?

What can I do?

Thank you
