samba - Nov 2003 - Backup from Linux onto Win2K-share

Hi.

I'm running Kernel 2.4.19 and Samba 2.2.5.

I'm in need to do a backup out of big SAPDB database (60 GB)
onto a share on a Win2K-box (all my databases have to backup
onto this w2K-box where they get saved on tape).

This works fine as long as it comes to 2 GB. Than it stops with
the message "file size exceeded". Obviously there is a file size limit
somewhere in Samba.

How can I get rid of it? I've tried to use a different kernel (2.4.22)
and I compiled as well as new Samba 3.0.1 from source (on a
different machine). But I still have the problem. Whats wrong?

(PS: NFS has a limit as well; 4 GB. But I need "unlimited" sizes)

Seems like you hit the limit of the filesystem on the w2k-box.
Not that of Samba.

Hi guys,

I'm sorry, but you're wrong.

I'm using NTFS (its a Win 2000 Advanced Server with ~ 1 TB Harddrive)
because of security.

I'm backing upwith SAP DB from a Windows-server to Windows-server without
any of this problems. All other servers (except Linux) can backup tons
of Gigabyte (the largest one is 120 GB) to that Windows-2000.

I only have this problem with my Linux boxes. And I can resolve on any
other Linux box running any distribution (Mandrake, RedHat, Suse ...).


Regards,
Carsten L?ffler

Are you tar-ing onto the remote drive? tar is limited to 2gb unless you use the
'gnu format' archive option....

No, I'm not really "taring". Right now I'm using following
command to mount
a share on the windows box:

smbmount //ntsrvsr3/cmdhp5 /mnt/backupsmb -o username=kwhadm,dmask=777

I also tried "mount -f smbfs ...."; but this failed as well.

Some more descriptions:
I have a Windows-2000-domain with ten W2K servers. One of the servers is my
backup server which has a share for each of the other servers where they
can put
their database-backups. As well I have a Linux box running a database; it
also
has to put its database backup to a share (named above).

A few words on my database: I'm running SAP DB 7.3. It has the option to
backup the database either on a tape or on into a file. If using
"file-backup" this
file can be anywhere on the linux, either in the local file system or in
NFS or in
SAMBA. SAP DB does not care on that as long as it can use a mount.
In Windows this works out perfectly for me (same technique).

Ive tried FTP, SAMBA and NFS: nothing can backup more than 2 or 4 Gigabyte.
Ive tried Suse Enterprise 8, Suse 8.2, Mandrake 8.1: same problem
everywhere.
At home I tried to manage it with XP-Professional and Suse Linux 8.2; there
I've tested a new compiled kernel and samba 3.0.1: same problem.

Sorry, but I'm getting "frustrated".

Carsten L?ffler

Hi.

Stefan, thanks for your ongoing support. I believe your mothertongue
is German as well but I will go on writing in English so everybody
can participate

In meantime I found in several other newsgroups that I'm not the only
one, but I did not find a solution)

Good idea. I did not know that there are any logfiles.
Can you give me a hint how to switch them on or switch
them to level 2? Thanks.

% Off topic: Why not use Linux w/ Samba as backup-server?

Yippie. I was wondering how long it might take before this question
will come up. Yes, I did. And: the other way around may work (see a
little later in that mail).
BUT: I HAVE TO USE WINDOWS. (to many arguments in this company to tell).

% I understand. Have you already thought of the possibility that the
% limit lies in the Linux-Version of your SAP DB? AFAI understand the
% problem occurs ONLY with that one DB.

Yes I did. I have SAP support and asked them:
they dont have any limit inside.

% Can you create a db-backup-file on a local partition of that machine?

Not yet anymore. The db exceeded the 50 % limit of the harddrive 2 weeks
ago. Right now the only backup I can do is on tape. This is not
working as well; but that's a different story. But before that date
(it was shortly after installation of the db) we made a backup on
harddrive. That worked out fine. With samba I've created a share on
LINUX to access the backup's folder and we were able to squeeze the
55 GB out of the box. But that option is not available to me anymore.

% Consult your manuals and support to make sure SAP has no limit on
% doing that so we can focus on the problem.

I did. SAP has no limit (un/fortunately).

Stefan, do you think there may be a "switch" in the kernel, or
something with my GLIBC? I've found some people telling others to
create a new kernel with a new GLIBC?!?! I dont know if that really
makes sense. In my eyes I would have made more sense to choose a
newer version of SAMBA.

Ive tried NFS as well. Same situation but it stops at a different
size; I think it was 2 GB (4 GB with Samba)
I dont know which process gives me the "filesize exceeded"; how
can I find out? I get this if try to use a "cp" (copy) with a
file larger than 4 GB exactly in that Moment when it reaches the
magic border. In case of using SAPDB I get an error from the
database saying "Broken Connection". When I examine the datafile
already backed up on the Windows box it has - surprisingly - again
the magic filesize.
I think that SAP Backup uses some kind of "internal TAR" because in
case running SAPDB under Windows there is no OS-driven "TAR". But
may be you are right. Right now I dont know how to figure out.
Anyway: I cannot tell SAPDB to use a different TAR. Ive already
thought about using STAR.

OK. But to let you know: I'm using EXT3. At home Ive tried REISERFS
and there it happened too.

Can you give your SAP DB backup program name of a pipe file
as destination? Then you can read from that pipe through a
decent "rsh" or "rexec" from W2K.
