Re: [Bacula-users] Win32 FD / Write error sending N bytes to Storage daemon

[Blake Dunlap]

$20 you have the other bacula comm channel failing due to timeout of the
state on a forwarding device. Dropping spool sizes is only increasing the
frequency of communication across that path. You will likely see this
problem solved completely by setting a short duration keepalive in your
bacula configs.

Re: [Bacula-users] Win32 FD / Write error sending N bytes to Storage daemon

[Mike Seda]

I just encountered a similar error in RHEL 6 using 5.0.3 (on the server 
and client) with Data Spooling enabled:
10-Jun 02:06 srv084 JobId 43: Error: bsock.c:393 Write error sending 
65536 bytes to Storage daemon:srv010.nowhere.us:9103: ERR=Broken pipe
10-Jun 02:06 srv084 JobId 43: Fatal error: backup.c:1024 Network send 
error to SD. ERR=Broken pipe

The way that I made it go away was to decrease "Maximum Spool Size" from 
200G to 2G. I also received the same error at 100G and 50G. I ended up 
just disabling data spooling completely on this box since small spool 
sizes almost defeat the point of spooling at all.

I've also been seeing some sporadic tape drive errors recently, too. So 
that may be part of the problem. I will be running the vendor-suggested 
diags on the library (Dell TL4000 with 2 x LTO-4 FC drives) in the next 
couple of days.

Plus, this is a temporary SD instance that I will eventually migrate to 
new hardware and add large/fast SAN disk to for spooling. This should 
explain the reason for the small spool size settings... This box only 
has a 2 x 300 GB drive SAS 10K RAID 1.

It'd be nice to see if anyone else has received this error on a similar 
HW/SW configuration.

Not really directly bacula related, but one of the concerns I have with
switching to IPv6 for LAN scale traffic is the performance of the
various offload features in the network adapters. Did you do any
throughput testing?

ZFS is a peculiar animal. I don't mean that in a disparaging way, I love it. 
But it may require 
rethinking backup.

As you say, ZFS send/receive doesn't provide for single file recovery. However, 
ZFS snapshots do. 
Using rolling ZFS snapshots takes very little space, even when kept over a long 
span of time. When 
I've asked the question you are asking in a couple of different forums, I've 
been told, use ZFS 
snapshots for single file recovery and use send/receive for protection against 
major failures.

Being a backup nut, I still feel I need a traditional backup system with a long 
cycle of tapes. In 
one case I have a multi-TB raidz2 array with a couple of years of daily 
snapshots, but still do 
traditional backups. I should clean out the snapshots, but space hasn't become 
an issue yet.

One hangup I ran into recently was with a sort of hierarchical backup approach. 
Workstations doing 
rsync style rolling snapshots to the server, so the backup space on the server 
is loaded with huge 
numbers of hard links. On the server side, gnu tar chokes on all that. ZFS 
send/receive doesn't give 
me the individual file recovery. But ufsdump handles the situation nicely, so 
maybe that drive gets 
reverted from ZFS back to ufs, at least until the ZFS tools evolve some more.

Amanda, by the way, will work with any of those, but doesn't, in and of itself, 
have anything to do 
with acls. You choose the appropriate underlying native tool and plug it in.

You need more than 1 storage device to have more than 1 volume loaded
at the same time. I would take a look at bacula-vchanger. It can help
you get around this limitation by creating a virtual autochanger of
disk volumes that you can access with more than 1 storage device but
still schedule all jobs to the autochanger device and let the software
handle the details.

I think we had "Maximum Volume Jobs = 1" so that we get a new file on the 
storage daemon for each job that runs.

Is there any way to keep the one-file-per-job feature and also allow multiple 
concurrent jobs to the device?

[Bacula-users] Bacula and ZFS

[Gabriele Bulfon]

I understand this may sound a bit wary, but: what are the benefits of using 
Bacula on a ZFS storage
rather than using Amanda or ZFS send bare utilities?
I know Bacula supports ZFS acls, but we also understand the faster option of 
zfs sending.
We also know zfs sending is not optimal for single file data recovery.
So, what is the status of Bacula with ZFS snapshots? How it compares to other 
solutions?
Thanks :)

You have "Maximum Volume Jobs = 1" in your pool. If you intend to use
a single storage device and this pool you can only run 1 job at a time
on this pool since only 1 job can be written to a volume a storage
device can only load 1 volume at a time.

If you have your concurrency set correctly (there are 5 or so places
were you enable concurrency in bacula-dir.conf) You probably have your
jobs going to different pools or volumes and since a storage device
can only load 1 volume at a time it can not process more than 1 job at
at time..

Hi,

We have Bacula configured to backup to file.  I'm attaching the relevant 
snippets of my director, storage daemon and file daemon configuration files.

When we run jobs that are configured to go to the same storage device, the 
first job runs and then all the subsequent jobs queue up with a message like 
this:

I'm sure that I'm just missing some switch somewhere - what am I doing wrong

Are these LTO3 or LTO2 tapes?
When bacula hits any kind of tape error it assumes the tape is full.
Check your dmesg.

Hello,

we are use an Autochanger with 8 Ultrium-LTO 3 tapes: seven for everyday and

+-++---+-+-+--+--+-+--+---+--+-+

TestVol1 belongs to a pool where we defined "Maximum Volumes Bytes = 0".

Nevertheless Bacula complains that it needs a new volume:

I have to agree there. I have been using IPv6 on my home systems (work
does not have IPv6 yet) and it's actually been faster then IPv4 to the

I.E. if you have a Bacula 3.0.3 then you should use b.a.t. at version 3.x.
If you have Bacula 5.0.3 then you should use b.a.t. from version 5.x. I have
never had problems with using b.a.t. when only patchlevel was changed, i.e.
5.0.0 - 5.0.3.

[Bacula-users] bacula IPv6 status (unofficially)

[Gavin McCullagh]

Hi,

just a short note to say that I've been testing Bacula's IPv6 support of
late and have generally found it to be good.

We have:

 - consoles connecting to the director over IPv6
 - director talking to SD and FD over IPv6
 - FD talking to SD over IPv6

As you might expect, if you configure Bacula to connect to a FQDN and
there's no  record, you just get an IPv4 connection.  If there is a
 record available, and a suitable IPv6 route, Bacula will generally try
to connect over IPv6 first and then if it gets a TCP reset (the far end
isn't listening on IPv6) or a timeout (maybe a firewall blocking the
connection), Bacula retries using IPv4 and life proceeds as normal.

A couple of things worth noting:


== Daemon Address Config ==

Thus far, we've found the best thing to do is to use the multiple address
configs with an explicit IPv4 and IPv6 record, eg (for the FD):

  FDAddresses  = {
ipv4 = { addr = my.fq.dn; }
ipv6 = { addr = my.fq.dn; }
  }

If you just use ip = {}, I've found that it only binds to the IPv4 address,
you need to explicitly have an ipv6 entry.  The same applies to the
director and storage daemon.  I'm open to better suggestions.

I think Bacula usually listens on 0.0.0.0 (all IPv4 addresses) by default,
but doesn't listen on :: (all IPv6 addresses).  I'm not sure if this is by
design, but I guess perhaps it's arguably sensible to only listen on IPv6
where it's explicitly enabled for now.  The main point is that it can be
enabled.

With IPv6 addresses, if you use SLAAC (stateless address auto-config), the
host's IP address is based on its MAC address, so it doesn't change.  If
the host uses privacy addresses the address may change.  On Windows 7, as I
understand it there are two addresses, one is initially created randomly
when you plug into that network but it stays constant on that network (this
is the one you expect to receive connections on and which usually goes in
the DNS).  A second address is for outgoing connections and changes at each
reboot (or every 24 hours on Windows Vista apparently).


== TCP wrappers ==

In my experience at least, if you use TCP Wrappers on Linux, you need to
enter the IPv6 address of the Bacula daemons which will be connecting.
Although a FQDN will allow an IPv4 host in, you seem to need the IPv6
address.  At a guess, this probably has more to do with tcp wrappers than
Bacula though.

This is one situation where Bacula will fail over IPv6 and not revert to
IPv4 which might still work.  This is because it's not a connection
failure, it's an authentication failure, so that makes some sense.

Gavin

I suggest trying a btape fill test command.

Just my 2 cents.

Ah okay, my mindset was a little too limited here ;-) I'm relatively new
to Bacula and did not have this feature in mind.

Nevertheless, IMHO the documentation could be a little more precise
here, and say "compare inode number" instead of "compare inode".

Thanks a lot.

158GB is probably a bit low. 85GB is definitely a problem. Is this something 
that has been getting worse over time? How old are the tapes?

Does your tape drive vendor provide any drive assessment tools? Eg HP provide 
Library & Tape Tools.

LTO is pretty smart and the heads are organised so that immediately after the 
media passes under the write head it passes under the read head and the data 
just written is read. If there is a problem reading it the data is rewritten. 
Obviously every time a block has to be rewritten the effective capacity of the 
tape is reduced. The drive assessment tools should tell you how much this is 
happening (margin, I think) and otherwise report the condition of the drive and 
the tapes.

Some of our tapes are down to about 175GB capacity. Curiously it is the set of 
5 tapes used on Fridays that are suffering from this problem which is strange 
as they are used about 5 times less than the other tapes.

 Good morning Radoslaw,

 I have several different versions... so I can't say you nothing as a 
 rule so you think any major version of bat can be used to access any 
 minor of bacula-dir?

What Bacula version do you use - 2.x, 3.x, 4.x, 5.x - all, some, only one?

I believe that you can use bat for the same major and any minor version of
Bacula.

 Hi John,

 Thanks a lot for you're response. So, it's not recommended to use a 
 version of bat with inferior or superior version bacula services?. It's 
 better to use the own shipped version with each source version?.

 Thanks a lot.

I definitely disagree. Bacula do have a central director concept. It means
that you can realize central backup system in your datacenter. What you only
need is a _one_ (central) director and infinite number of clients, storage
daemons even catalog databases and consoles.
Or am I misunderstood your comment?

Check if you have a Max Jobs parameter set for more then "1" for all:
director, clients, storage daemon.
You can check it by console command: show director, show client, show
storage
