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

Kern Sibbald Thu, 12 May 2016 12:27:12 -0700

Hello,

Well, I was sure I saw it in one of your prior emails, but I just re-read them and cannot find it, so I must have just gotten confused. Sorry.

However, please do not try to compile Bacula without largefile support, it is very likely to break it. Bacula counts on having 64 bit file addresses.

Best regards,
Kern

Hi Kern,

in this DR machine I'm sure is 7.2.0 because it is a fresh install.

In the primary site I have upgraded from 5.2.3 to 7.2, but I'm quite sure that the upgrade was done well because I install in a PREFIX path and create a soft link to the binary:

#which bacula
/opt/bacula/sbin/bacula

where sbin is

sbin -> /opt/bacula-7.2.0/sbin

Where you have seen that I have used the 5.2?

Thank you

Carlo,

I have not looked at this in detail, but it seems to me that you are running a version Bacula 5.2.x, yet at the same time, you are doing a bscan with a bacula-7.2.x. If you are doing this, please note that this is not supported, and if you mix and match Bacula Directors with their catalogs with Storage Daemons or SD tools of a different version, you will definitely have serious problem.

Best regards,
Kern

Now I trying with 2 options:
1 - # ulimit -c unlimited

2 - ricompile bacula with "--disable-largefile"

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

Thank you

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.

Hi Heitor,

this is my information:

Version: 7.2.0 (14 August 2015)

I compile Bacula with:

./configure --prefix=/opt/bacula-7.2.0 --with-mysql --with-db-name=bacula --with-db-user=bacula --with-db-password=bacula --sysconfdir=/etc/bacula/

The command I use is:

this is the last log:

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
