Yes - and if it's about to do anything which takes the changer offline
the web ui gives a warning message and asked if you want to continue.

I hope you changed the password and put the changer in its own IP subnet
after that.

I wrote some kludgy shell scripts (originally for Neo4000, then Neo 8000
and now Quantum i500 - portable as far as I know) which automate loading
and unloading of the changer (imported tapes are scattered randomly
around available slots to ensure even wear and tear) - these mean that
all operations staff have to do is open the magazine to load/unload
tapes when emailed to do so by Bacula.

Dan can probably improve them considerably.

As an adjunct to that another script works out which tapes are oldest
(if in the scratch pool) or about to expire (if none are in the scratch
pool) and asks staff to pull them out of the safe.

I also submitted some chages to the mtx-changer script a while ago which
check that the changer's actually ready before attempting to send it
commands. Kern's been sitting on them for a couple of years.


There are some pretty whizzy things you can do to monitor tape health
when a tape is in the changer using the sg_attr and sg_logs commands
that go _far _ beyond Tapealart or smartmontools capabilities.

I've submitted a number of updates to sg_utils and am in the process of
(slowly) reverse engineering what I can from the MAMs that's not well
documented using text output provided by veritape (proprietary, windows
tool from mptapes.com which reads MAMs).

Selfish motivation is (of course) to reduce the amount of time I have to
spend manually scanning tapes with the windows program/standalone
scanner then interpreting output. All of that information is available
when the tape is in the drive and with appropriate MAM reads at
load/unload it's possible to have the bacula server tell me when a tape
is approaching end of life (this is far more accurate than the metrics
bacula uses of simple load cycles.) - and more importantly, when tape
drives are going bad.

Having spent several man-years dealing with the fallout of bad LTO tapes
damaging drives and then those drives damaging tapes, I want to minimize
the pain if it ever happens again.

(LTO drives even return detailed information about the condition of each
of the heads if queried the right way. This data is interpreted by IBM
or HP's proprietary tools to give reports but they use the same queries
as sg_logs does to get it)

Re: [Bacula-users] Problems getting a tape library to work under FreeBSD

[Kenneth Garges]

Permissions and ownership are ok. I think I figured out the problem.

Both mtx and chio would work for a while, then stop working returning only 
“Inappropriate ioctl for device” or other errors. The culprit I think is a 
library management tool by Quantum. The library provides a web interface that 
allows you to check status, move tapes around, and various utilities. 

Problem is if you use that web interface it gets the server (both Bacula SD and 
Director on the same FreeBSD box) wedged such that mtx and chio always fail.

Unknown to me, the operations staff had been using that web interface while I 
was testing. After I asked them to stop my system seems to work reliably. 

Thanks to all that chimed in on this thread. It was very helpful.

Re: [Bacula-users] Number of files mismatch!

[Martin Simmons]

OK, so it looks like the data on the tape is still OK.

The Volume=0 in the error message is what Bacula found for the "file" position
on the tape after trying to move it to the end of data.  This might be a bug
in the OS driver or tape firmware.  Were there any syslog messages at that
time?

You could try running btape and issuing the commands

rewind
cap
eod
status

to see what it reports.  (I don't think this will write anything to the tape.)

Also, have you run the btape test command successfully with this configuration
recently?  (Beware that this will overwrite the tape.)

[Bacula-users] trying to build a static bacula-fd

[Mike Eggleston]

I finally have bacula set up for more testing. I'm trying to build a static FD 
for other servers (GNU/Linux).
I'm using the line:

./configure --with-mysql --with-systemd --with-dump-email=bacula@localhost 
--with-job-email=bacula@localhost --enable-client-only --enable-static-fd 
--without-ssl --disable-libtool

And getting the error:

checking for library containing dlopen... (cached) -ldl
checking for PostgreSQL support... no
checking for MySQL support... yes
checking for MySQL embedded support... no
checking for SQLite3 support... no


You have specified two or more of the
supported databases: MySQL, PostgreSQL, or SQLite3.
This is not permitted when not using libtool Please reconfigure.

Aborting the configuration ...

You can see configure has detected no PostgreSQL nor SQLite3 and I've only 
selected MySQL on the command line.
What do I do now?

TIA

>>and backups will not run.



>>Device is BLOCKED waiting to create a volume for:

It means that there is no usable volume available, and so Bacula asks you to 
create a new one.

instead of giving label manually you can follow these steps:



first take backup of your configuration files.



1. After looking into your configurations files, you can define these 
primitives in "Pool resource" in your "bacula-dir.conf" file and "Device 
resource" in your "bacula-sd.conf" file





# bacula-dir.conf



Pool {

  Name = File

  Pool Type = Backup

  Label Format = Local-

  Recycle = yes  # Bacula can automatically 
recycle Volumes

  AutoPrune = yes# Prune expired volumes

  Volume Retention = 365 days# one year

  Maximum Volumes = 100 # Limit number of Volumes in Pool

}



Here:

The Recycle = yes :It is used to permit automatic 
recycling of Volumes whose Volume retention period has expired.

The AutoPrune = yes  :If AutoPrune is set to yes Bacula 
will prune file records that are older than the specified file retention period

The Volume Retention = ttt :It defines the length of time that Bacula 
will keep records associated with the Volume in the Catalog database after the 
End time of each Job

The Maximum Volumes = nnn: it is used to define the record in the Pool 
resource to limit the number of Volumes that can be created.





# bacula-sd.conf



Device {

  Name = FileStorage

   Media Type = File

   Archive Device = /bacula/backup

   Random Access = Yes;

   RemovableMedia = no;

   AlwaysOpen = no;

   LabelMedia = yes;# lets Bacula label unlabeled media

   AutomaticMount = yes;   # when device opened, read it

}



Here:

The Automatic labeling work is to give the Storage daemon permission to 
automatically label Volumes by adding LabelMedia = yes to the Device resource.

The AutomaticMount = yes is used to read devices when they are open.





After performing these changes in your configuration file restart your mariadb 
and bacula services



$ Systemctl restart mariadb

$ Systemctl restart bacula-dir

$ Systemctl restart bacula-sd


Thanks & Regards
Soniya

Hello Martin, 

Problem occured last night,

05-Feb 21:01 JobId 96: Error: Bacula cannot write on tape Volume "ROMBQ006" 
because:
The number of files mismatch! Volume=0 Catalog=71
05-Feb 21:01 JobId 96: Marking Volume "ROMBQ006" in Error in Catalog.

Then I bls'ed the tape :

bls: butil.c:293-0 Using device: "/dev/nst0" for reading.
06-Feb 08:57 bls JobId 0: Ready to read from volume "ROMBQ006" on tape device 
"Lecteur_LTO6" (/dev/nst0).

Volume Label:

VerNo : 11
VolName   : ROMBQ006
PrevVolName   :
VolFile   : 0
LabelType : VOL_LABEL
LabelSize : 164
PoolName  : QUOT
MediaType : LTO-6
PoolType  : Backup
HostName  : server
Date label written: 29-Jan-2018 16:39

Then 6 "Begin Job" / "End Job" 

Then

06-Feb 09:07 bls JobId 0: End of Volume at file 71 on device "Lecteur_LTO6" 
(/dev/nst0), Volume "ROMBQ006"
06-Feb 09:07 bls JobId 0: End of all volumes.
Bacula "End of Tape" label found.
