[Bacula-users] Which side to start an upgrade?

2007-02-28 Thread MaxxAtWork

Hello,

when upgrading a bacula backup environment with many clients
from which side is wiser to start? Clients or director/sd ?
In other words which of these two situations is less likely to be troublesome:
- old client talking with new director/sd
- new client talking with old director/sd

I'm thinking of an environment where at least some of the machines have bacula
installed with e.g. Linux distro packages, so 'installing in an
alternate directory'
is not an easy option to follow, and the upgrade cycle is not
applicable all-at-once
on all the machines involved, otherwise some important backups would be skipped.

Thank you
-- 
Maxx

Re: [Bacula-users] Few notes regarding the restricted console commands

2007-02-28 Thread Kern Sibbald

Hello,

Thanks for the feedback.  I'll add these items to the documentation. 
As for the problems of details of show and list, I'm not sure it is worth 
the effort to add finer grain ACL testing, however, I will note in my todo 
list and see if it is possible.  In general for the moment, you will need to 
not enable those commands if you think they will cause a security violation.

If you find any other cases where users can get at information that does not 
belong to the, please let me know so that I can either fix it or document 
it ...

See below for more comments:

 Hi

 Recently I tested the patch that fix the bug 767 (see bugs.bacula.org). The
 patch works fine -  the restricted console is not able anymore to cancel
 running jobs that not belongs to it.
 With this occasion I tested other commands and I found few things which, in
 my opinion, should be mentioned, maybe for future references:

 - the shortcuts for commands (for example st or sta instead of
 status) can't be used in a restricted console, except the case when the
 shortcuts are literally mentioned in the CommandACL.

Yes, this is correct. Since shortcuts are not always unique you are required 
to add the exact shortcut that you wish the user to be able to use.

 - the command help retuns the full commands list and, for a restricted
 user, 

I'll look into filtering this ...

 typing commands that returns ... is an invalid command can be 
 frustrating because the user have no idea about the allowed commands

Can you explain more in detail what you mean or what you would like it to do?
It might be possible to convert more of those into unauthorized command, but 
isn't it a lot of code for something rather minor?  If it is occurring at the 
main command level, it is easy to fix, however, if it occurs 
in subcommands, it could be very pervasive.

 - the show command returns information related to other jobs than the
 ones configured in the restricted console configuration file

Yes, and it is hard to know how to filter it.  However, I will take a look at 
it, in some cases, it may be obvious such as show catalogs could easily 
apply the CatalogACL ...

 - the query command allows queries against job ids different than the
 ones related to the restricted console. Based on this, I get the volume
 names and job ids for other bacula clients and I tried to restore some
 files. 

I'm not going to be able to do much about the query command or with the SQL 
command.  Both take user input which cannot be easily parsed by Bacula -- 
i.e. I would need to add a full SQL command parser to make it work correctly.

For the query command, a workaround is to give the user his own local copy.
A better solution would be to add the Query Command directive to each of the 
restricted Console resources -- I think this probably should be a feature 
request, but it is something I would accept.

 It's true I wasn't able to restore any files from other jobs, but I 
 was able to browse the files list. One mention here - this is true only
 when the restore command is used and not when the restore tab is used
 in wx-console.

Can you explain why the restore command gives more information that the 
restore tab in wx-console?  It sounds like wx-console has implemented 
something that should be included in the core code ...

Regards,

Kern

 Hi

 Having 2 or more consoles opened to bacula directory, only one console gets
 the messages. There is any way to send the messages to all opened consoles?

No -- that would require some sort of Feature Request, and in fact, I don't 
really know how to do it correctly.

Each console should get the messages or answers to queries and commands that 
it generates (not necessarily including job output).

 Any idea would be appreciated. Thanks.

Re: [Bacula-users] Cannot label tape from bconsole

Really thanks Andrea.. That is a side of Linux I never investigate from 
my side and I guess I'll have a good time digging inside.

 Can you tell me what method you have in mind for changing permissions? A 
 shell line inside /etc/init.d/bacula-sd.conf (I use Fedora) with the 
 chmod previously said or a different command?
 
 I suppose you're using a recent (2) version of fedora, so your system
 should be running udev.
 If that's the case, you just need to tell udev which
 owner/group/permissions you want that device node to be created with.
 
 Create a file named 10-tape.rules in /etc/udev/rules.d with the
 following line in it:
 
 KERNEL==nst0, OWNER=foo, GROUP=bar, MODE=0660
 
 If you don't need to set the owner or group simply leave out the
 corresponding section.
 
 Taking a look at the udev documentation on rule writing might also be a
 good idea, since there is much more you can do with it.

Re: [Bacula-users] Bacula Restore keeps crashing with Block checksum mismatch

2007-02-28 Thread Sven Hendriks

Hello,

my problem seems to be solved. It seems to have something to do with the block 
size. I set both the minimum and the maximum blocksize of the device to 64KB 
and the restore works:

Device {
  Name = TestStorage
  Media Type = File
  Archive Device = /mnt/notfallserver/vollbackup
  LabelMedia = yes; 
  Random Access = Yes;
  AutomaticMount = no; 
  RemovableMedia = no;
  AlwaysOpen = yes;
  RequiresMount = no;
  Minimum Block Size = 65536
  Maximum Block Size = 65536
}

It works with 16KB fixed block size, too. Beforehand I did not set the block 
size.

Greetings,
Sven Hendriks

   Hello,
  
   I'm running Bacula 2.0.2 built from source on the following system:
   XEN 3.0 with Gentoo, Kernel 2.6.16 as Dom0 running bacula-dir and
   bacula-sd. One deamon bacula-fd is also running here for test restores.
   File system is Ext3. Debian, Kernel 2.6.16 as DomU running one file daemon
   for backup. The file system here is XFS. The backups are done from the 
   DomU
   file daemon and are stored via the storage daemon on a samba share with
   NTFS mounted with the cifs option in the Dom0.
  
   Backups are running well, unfortunately the Restores do not. Everytime I
   try to restore a backup sooner or later I get an error message like
  
   Error: block.c:317 Volume data error at 0:2068512761!
   Block checksum mismatch in block=65353 len=64512: calc=3deeeba7
   blk=962bd82e
  
   and later
  
   Error: attribs.c:409 File size of restored file X not correct.
   Original Y, restored Z.
  
   and Bacula stops.
  
   I tried to restore from the samba share to the same samba share into
   another directory via the file daemon on Dom0 and from the samba share to 
   a
   XEN DomU with XFS via the file daemon on DomU. In both cases I get the
   error messages above. The backups are running at night, so it is very
   unlikely that file sizes are changing during backup. I hope my 
   descriptions
   are not too confusing :-) I have no idea what causes this error and I'd be
   grateful for any hint that may help to solve my little problem.

Re: [Bacula-users] bacula-dir won't start from a script

Hi Arno,

I'm using
bacula-mysql-2.0.2-1.el3.i386.rpmhttp://downloads.sourceforge.net/bacula/bacula-mysql-2.0.2-1.el3.i386.rpm?modtime=1170518065big_mirror=1on
RedHat Advanced Server v3.

Bacula v1.38.1 worked fine.

I tried with #!/bin/bash in the start of my script.

Which OS do you use, and where does the Bacula installation come from?
Packages, compiled yourself, whatever... also, has the start script been
modified by you?
