[Bacula-users] Doesn't want to recycle tape in the drive

[Adam Cécile]

Hi,

Here is my problem:
I have five tapes (Dailly-00[1-5]).
Let's assume Daily-005 is purged and Daily-001 is used (but data expired).
If Daily-001 is in the drive, Bacula won't recycle it, instead it will 
keep asking for Daily-005.
If I set Daily-005 as disabled, bacula automatically purge Daily-001 and 
recycle it.

Any tips ?

Best regards, Adam.

(tested with bacula 2.2.0 and 2.2.5 on a Debian Etch system, with only 
one external LTO2 Dell tape drive).

For the single-spindle tapes, like DLT and LTO, retensioning should 
never be needed. Thus it's only reasonable for the drive firmware to 
not accept this command.

[Bacula-users] What is the strategy for MaximumPartSize?

[Hydro Meteor]

Hello all,

This question probably has an obvious answer that I'm missing, but with
regard to DVD backups, the Device Resource in the Storage Daemon
Configuration has an optional Directive named "MaximumPartSize". From the
Bacula Usesr's Guide, I think I understand that setting a value for this
Directive (e.g., 800 MB) is a way of controlling how many bytes (from the
Client backup target) ends up in the Bacula spool directory at one time
(before the bytes get copied to the DVD optical disc). Is this a correct
assessment that MaximumPartSize in essence acts as a sort of flow control
from backup target on the client to the spool to the DVD disc that requires
mounting?

Thanks,

-H

Thank your for your feedback, there is really nothing to apologize for.  We 
need to keep all our discussions open to all points of view. The only request 
that I make is to keep the conversation civil, which certainly was the 
case  -- if you want to count mistakes (I'm not counting), just look at 
bugs.bacula.org and about 90% are mine :-)  

Thanks to David and you for the link, I have now added it to the web site on

It appeared that instead of a simple flag, the director uses an MD5 hash of
the fileset definitions which it stores in the FileSet database, which it
creates only if 'ignore fileset changes' is set to no (and upon the first
full backup of a fileset, obviously). That hash is compared to the state of
the fileset before every non-full backup job. 

Deleting the last entry there caused Bacula to consider my FileSet as the
newest version again, and thus to continue doing incremental updates.

[Bacula-users] ClientRunAfterJob Problems

[Dep, Khushil (GE Money)]

Hey all,
 
I've my jobs setup with the line ClientRunAfterJob = "rm -rf
/path/to/source/*" which as I understand it should issue that command on
the client after job runs? Looking at the job log on the director, it is
issuing the command and yet, it does not seem to be executing on the
client as the files are still present. Any ideas? The bacula process on
both the dir and fd are running as root.
 
Khush.

Well, your request is a bit general, so I am not sure what you want us to do 
as you did not suggest any specific solution. I did take a look at the bugs 
list, and in the beginning very few people filled in the Bacula version or 
other information that we request.  However, recently, nearly everyone fills 
it in.

It is unpleasant and not very practical for us to constantly request users to 
put in information if it is not really critical, because it just delays the 
response and makes more work for us.  I think our Bugs web page is pretty 
clear on what we need, and if we don't find the information we need, we 
sometimes either request it or close the bug and send the reporter back to 
the web page documentation. The ideal situation would be that everyone fills 
in everything and provides *all* the info we need, but this is not the case, 
and the problem is rather universal.

When we supply a patch, the patch is very clearly labeled as to what version 
it applies, and if we fix a bug generally specify in which version it is 
fixed when we close the bug -- sometimes in the specific field provided, and 
sometimes as a bugnote, and sometimes both.

A good resource for finding problems and fixes is the technotes or ChangeLog 
that are released with every version and kept current in the SVN.  The SVN 
technotes are typically up to date, and it is really rare that we fail to 
mention a problem or a bug fix.

As part of our effort to develop extensive professional support, at some time 
in the future we will have a more complete knowledge base, and I expect that 
to be much more easily searched.  However, a knowledge base is very expensive 
to create and maintain (you have to pay people to do it), so I am not sure 
whether it will be available only to customers who pay for its creation and 
maintenance or to the general public.

I'm not sure what more we can do.

I can think of a number of instances when retensioning is needed - 
particularly if the cartridge has been dropped and the tape pancake has 
likely slipped slightly.

Still struggling with why this feature isn't working for me, I have set
the following in bacula-dir.conf for the job in question:

Re: [Bacula-users] Bacula doesn't see tape in drive after label barcodes

[Arno Lehmann]

Hi,

ok, I captured some debug output regarding the issue when the SD can't 
detect a usable volume in the tape drive.

This only happens (in my installations) when the pool requested is 
changed. In this case, the full backups from one pool ran fine, and 
the incremental backups for the week started. The former use the pool 
"Archive", the latter the "Daily" one.

The state in which I found the system was as follows:
- A usable tape from pool "Daily" had been loaded into the libraries 
tape drive (coming from slot 8, having the name 000974L2). This volume 
was selected according to the retention periods, and loading obviously 
worked.

The debug trace output (this one at level 1000, I believe) shows the 
following when I usse a mount command:

This is one of the reasons callbacks are evil (apart from the extra 
network loading). They just don't scale.

There are a bunch of supposed "antispam" measures which are bigger 
problems than that which they purport to solve. C/R and callbacks fall 
into this camp - especially if someone really is the victim of envelope 
forgery attacks (Callbacks and C/R have been known to effectively cause 
DDoS on smaller mailservers)

Probably there is no file or directory named '*' .
I think you dont have wildcard expansion here.

...snippel
In addition, the command string is parsed then fed to the OS, which means that
the path will be searched to execute your specified command, but there is no
shell interpretation, as a consequence, if you invoke complicated commands or
want any shell features such as redirection or piping, you must call a shell
script and do it inside that script.

Re: [Bacula-users] Bacula doesn't see tape in drive after label barcodes

[Shon Stephens]

So far so good. I can just post this as a workaround. For me, its only
happened when labeling from
barcodes.

[Bacula-users] bat: client list jobtotals

[João Henrique Freitas]

Hello,

Anybody has the same issue in bat when:

1- Client -> Rigth click on any client
2- Select "List Jobs of Client"
3- Select (on left panel) "JobList of Client xxx" and right clik on it
4- Select "List Jobs Totals in Console"

On this time the bat show a error about list jobtotals4 command.

In bacula documentation, the command in question (list jobtotals) has no
argument.

On the file src/qt-console/joblist.cpp, in function:

void JobList::consoleListJobTotals()
{
   QString cmd("list jobtotals");
   cmd += m_currentJob;
   if (mainWin->m_longList) { cmd.prepend("l"); }
   consoleCommand(cmd);
}

If I comment out the line cmd += m_currentJob; bat works.

Thanks

[Bacula-users] Bacula speed limitations?

[Shon Stephens]

I was just wondering what the factors limiting the speed with which
Bacula writes to tape are? I performed some testing on my LTO-3 drive
and found that the theoretical limit is 276G/hr, while my backups are
writing at around 174G/hr. The client is the Bacula system itself. The
FD is reading files from a filesystem that resides on a SATAbeast FCA
attached storage array. The files are Oracle dumps, and the options I
have specified are:

signature = MD5
verify = pins5
sparse = yes
noatime = yes

The only compression I am using is the tape devices compression, which
at 2:1 compression should be over 500G/hr. I wrote a 3.4T job in
19h30m. At what seems to be a compression of 1.5:1. This should still
be faster than the 174G/hr its acheiving.

Would using MD5 signatures slow this up?
Are any of these settings tunable and do they affect Bacula performance?

[Bacula-users] Bacula backup running amok with "not configured to autolabel Volumes" messages

[Win Htin]

Hi folks,

I have a RedHat EL4 server connected through FC to an IBM TS3200 tape
changer with single LTO4 drive with 44 slots. The bacula version is 2.2.5. I
have set the label to use the barcode labels and wiped all 25 tapes in the
changer clean with the command "mt rewind && mt weof && mt rewind" to make
sure all previous label and data entries from earlier tests are completely
gone.

Entry from bacula-sd.conf:

Label Type = IBM
Check Labels = yes
LabelMedia = no;

Following is the sequence of my test run:

1. Checked status of the autochanger just before the job was started.
Confirmed NO tapes loaded in the tape drive.

message spitted out incessantly.
06-Nov 14:10 nfsserver-sd JobId 1: Warning: Device "LTO4_1" (/dev/IBMtape0)

Any ideas why Bacula is unhappy with the tape(s)? Am I doing something wrong
with the labels? I've been testing Bacula for the plus 1+ month and it
consistently gets messed up with the tapes. Help is much appreciated.

Re: [Bacula-users] Autochangers over Fiber Channel

[Mike Seda]

Hi Flak,
I use mtx all the time with my Quantum PX502 Autochanger (LTO-3, FC, One 
Drive) on RHEL 4 AS (32-bit). The only gotcha is that FC AL does not 
work with the autochanger, and I was forced to use FC Point-to-Point.

If you are doing FC Point-to-Point you need to have an FC switch or a 
multi-port FC HBA. My FC HBA only has one port. I was lucky enough to 
have extra ports on my FC switch. I used these three extra ports on the 
FC switch to make the connection between my HBA, the autochanger 
robotics, and the one drive.

I hope that helps.

Best,
Mike

There are problems with the embedded Python:

1. Very few people use it.
2. I think most people would prefer Perl
3. It doesn't function perfectly since it is impossible to call certain 
functions.  I forgot the details but it is pretty annoying.
4. The links always print warning messages because they continue for something 
like 4 versions now to use deprecated code for temp files that has security 
problems.
5. The linking code is really quite complicated.
6. Python is single threaded, which means that if multiple Bacula threads try 
to use Python at the same time, I have to block them allowing only one to run 
at a time.
7. Given the above I would rather not support it -- and no one else is likely 
to come forward and do so.

I don't have any intention of doing away with the basic labelformat.  However 
the vars code will eventually go, because it is mind bogglingly complicated 
and doesn't really have all the functionality that the user wants.  I was 
hoping to replace it with the Python code, but Python just didn't work out.

Yes, so use Python for the moment.  At some point you may have to change, 
though I hope to provide you a way to get to Python without having it linked 
in -- since I don't yet have it running, I cannot say what changes it may 
need to the scripts.

Yes, I have a good idea, am working on it, but aside from a dummy little demo

Version 3.0, probably won't be out until June of 2008 at the best.  I hope it 
will have a better alternative.  Once I am sure I have a better solution, all 
the old stuff will be removed in the following version -- after announcing 
it.

Yes, 2.2.6 is due out in a week or so, and is a pure bug fix.  The current 
2.2.5 is looking really stable, and most of the bugs I have been fixing for 
the last few months are long standing one ...

Both Python and variables for LabelFormat are likely to remain in in the 
initial 3.0 release.  Unless I have a Python replacement, which is unlikely.

The key question is: When do you get these lines?

At program shutdown, there's not much to worry about them as they all 
show small chunks of memory.

You forgot another quite important piece of information: The version 
of Bacula you're running.

Re: [Bacula-users] multiple autochangers

[Mike Seda]

All,
I am interested in purchasing another autochanger.

I am under the impression that the only way to conveniently (without the 
annoyance of manual shuffling) use two autochangers is to have different 
MediaTypes assigned to them. Is that correct?

Thx,
Mike

Ignore the warning for now, it's not an error.

The problem is that this volume is not recognized.

I think you should do the following:

1. umount the device from bconsole
2. issue 'setdebug level=400 trace=1 sd=LTO4_1',
3. wait for any messages, then 'setdebug level=0 trace=0 sd=LTO4_1'
4. find the lines in the resulting nfsserver-sd.trace file in the
SD's working directory where the tape is not accessible (you might
see something regarding a "rewind error".
5. use mtx to unload the tape from the drive
6. use mtx to load that same tape to the drive again (don't ask...)
7. in bconsole, issue 'mount sd=LTO4_1 slot=21'

According to my theory, your job should run then.
If it does, report back, please - it seems as this is a problem that 
affects several installations.

If I'm guessing right, you'll find that everything works ok as long as 
tapes from among one pool are exchanged, but once you use another 
pool, Bacula doesn't accept the tape because it can't rewind it.

For me, this looks really weird.

If I get this confirmed by others, I'll file a bug report - unless 
someone beats me at it :-)

Yes, that's still correct.

You can - and probably should - also set up different pools for use on 
the devices, so that you don't have volumes from one pool assigned to 
both devices, but that's an extra feature :-)

One filesystem would be enough - you don't have to foresee the space

It should work, at least.

Of course, using one filesystem for several storage devices can limit 
the overall throughput. If that's limited by network speed, yozu won't 
have a problem. If you're backing up several FC-connected drive 
arrays, this will be more of a problem :-)

 You allow only one job per Volume.

 You either need another storage device, or have to allow more

If you want to have different retention times for full, differential, 
and incremental backups, for example. You can set up your pool sizes 
in a way that you minimize the space occupied by jobs that are already 
pruned, but are stored on volumes still in their retention periods.

[Bacula-users] Auto-labeling volumes from Python

[Ben Beuchler]

The example DirStartup.py shows an example NewVolume method that just
assigns a generated volume name to job.VolumeName.  Is that all that's
needed for the system to label a new volume?  Does it just label a new
volume using the defaults defined in bacula-dir.conf?

Thanks!

Possible. I wouldn't claim to know this, though :-) I suppose there

Actually, I start to prefer python - much more readable after a while,

Yes, that's something I and others noticed. In fact, this would need

Hmm. I've been playing with embedding python into a C program, and 
found it reasonably straightforward. And that's from someone who

That's a serious problem, I think.

The support issue is probably the thing with the most weight here. But

No. Either you use the "plain" variant with LabelFormat, or you use 
the python hooks, but the samples should be heavily modified. You 
probably want a new volume name for each label you create, for example...

In fact, to implement a simple auto-labeling mechanism, you don't need 
python. Just use "LabelFormat=Poolname-" and you get names like 
"Full-0001", "Diff-00123" etc.

There's no real significance... nothing is mode 0, the default settings,
l is mode 1, m is mode 2 and a is mode 3. For some drives this allows
you to set the compression ratio (mode 1 being the lowest, mode 3 the
highest) some others use it for density settings etc etc but usually
it's not supported and unused.

Michel

[Bacula-users] Last piece of the puzzle...

[David Gardner]

Hey folks,

I have four servers I want to backup to a single volume, e.g., one file on BU 
server or one tape (drive). It looks to me that I simply need the volume to be 
appendable but I don't see a configuration setting to make this happen.

Currently, when a server's file set is backed-up, Bacula wants an appendable 
volume or a new media. I'm so close, I can taste it

Re: [Bacula-users] Bacula using one drive in a Vchanger

[Elie Azar]

Hi Josh,

I have upgraded to bacula 2.2.5 and I'm still having the same problems.

It seems like drive-1 in the vchanger is never used. Have you ever seen it
used, and if so, what kind of configuration do I need; I followed the
instruction in the HowTo document (Rev 0.7.4 2006-12-12). I tried many
configurations but I still can't get it to run more than one job. If I start
a second job it will fail.

What I'm trying to accomplish is the following: I created an LVM disk using
2x500GB disks. I created a vchanger with 2 virtual disks to backup to the
LVM. Originally I created the vchangers with multiple 500GB disks, but I
changed to use the LVM; that setup didn't work either. Even with one
vchanger per 500GB disk, I still couldn't start more than one job at a time.
I can the relevant parts of my conf files if that helps.

I would like to run concurrent jobs to backup to different volumes on the
LVM disk. Bacula doesn't seem to be able to do that. Every time I start more
than one job, each one after the first fails.

Here is a sample console output illustrating this problem:

Well, I was quite sure I saw a technical document once where it was 
stated that, for single reel cartridges, retensioning was not 
necessary because tape tension was actively controlled when moving the 
tape.

Thus, once a tape is loaded and used, the tension would always be 
correct (implying that, once you read a tape to its (physical) end and 
rewound it, the tape on the cartridge reel would have the normal 
tension again).

Unfortunately, I can't locate this document any more :-(

But IBM, for example, in 
http://www-1.ibm.com/support/docview.wss?uid=ssg1S7001798&aid=1 states 
that the Retension bit in the SCSI commands where it could be used is 
not supported.

HP and Quantum don't have corresponding information available.

So, even while it might seem a good idea to have retensioning 
procedure for single reel systems, there are reasons to assume you 
don't need them. Furthermore, all the manufacturers agree how to 
handle cartridges you dropped: don't use them (personally, I wouldn't 
be that strict...)

Re: [Bacula-users] Can't run concurrent jobs to the same resource

[Elie Azar]

Hi,

I implemented a setup with one LVM disk (2x500GB drives) and an autochanger
with 2 virtual disks (disk-0 and disk-1) following the instructions in the
Vchanger HowTo document (rev. 0.7.4 2006-12-12).

I created the conf file for the vchanger, and I updatd the bacula-dir.conf
and bacula-sd.conf files with the approrpiate entries. I also setup "Max
Concurrent Jobs = 20" in the director conf file for the directives:
Director, Storage, Client, and Job, and in the storage deamon conf file for
the directive: Storage.

I can start one job at a time, and things work fine. But, if I start more
than one job, then there is no concurrency and every new job will fail.

Is there some trick for getting concurrency to work in bacula; I thought it
would just fall into place once things are setup properly. It seems to
always use disk-0 to bind to the volume it is backing up to; it never uses
disk-1, even though it part of the changer. Have you seen disk-1 used in
similar situations.

Thanks you for your help,
Elie

 The intention is to have a single job per volume. What I would like
 is for Bacula to pick up a new volume for the new job, even if it's
 on the same storage device. I would imagine that it should be able

[Bacula-users] can't restore ACL of /tmp/bacula-restores/*

[Doug Sampson]

I am testing the restore function of Bacula 2.2.5 on FreeBSD 6.2 and in the
process of restoring ~20,000 files recursively from the /var directory, I am
seeing numerous error messages as follows:

Is the Bacula database corrupted? Why aren't the ACLs not being restored?

Re: [Bacula-users] Bacula speed limitations?

[Ryan Novosielski]

It is quite possible that your catalog database cannot keep up with your 
backups. I'd start there.

What if the incremental and full backups are to different media?

My practice is to have separate Incremental and Full pools, and
to run the daily Incremental even on Full Backup day, so that if
there is a media error on the Full tape, I still have a
reasonable hope of restoring everything to the state of that day,
using the combination of the previous Full tape, and the
intervening Incrementals.  

In my setup, the Incrementals usually complete before any of the
Fulls start, but if something should prolong the Incremental so
it is still running after the Full starts, I could still see a
point to letting the Incremental run (unless its start time is
delayed to the point where it is basing its choice of what to
back up on the time of the concurrently running Full, rather than
the previous Incremental).
