Btape Test - Append Files Test

Aaron Greenblatt
Hello,

I am attempting to use Bacula on a backup server and am having trouble with btape test in the append files section. I have read the documentation, searched on Google, and updated the firmware on my SAS card and tape drive. I don't see any particularly helpful log messages on the system. Any thoughts on where I should look to continue troubleshooting this? Could it have something to do with the SCSI driver in the OS?

Configuration is as follows: Debian 8 with Atto H1280 (also tried H644) SAS HBA and HP LTO6 tape drive. More details below.

Thank you.

Best,
Aaron

Re: Btape Test - Append Files Test

Kern Sibbald

Hello,

Please take out the:

Hardware End of File = no

and

Device Type = Tape

then try the test again.  If it fails please post the btape output, the OS you are running, the Bacula version, and where you got the binaries.

Best regards,

Kern

Re: Btape Test - Append Files Test

Aaron Greenblatt
Hi Kern,

Thanks for your help!

I removed the two lines you mentioned and had the same result.

The btape output is below. I'm running Debian 8.8 (kernel 3.16.0-4-amd64). I downloaded the Bacula 9.0.1 source from https://sourceforge.net/projects/bacula/files/bacula/9.0.1/ and compiled the binaries on my machine. The binaries are dynamically linked, so I added "/home/agreenblatt/software-bacula/bacula/src/stored/.libs" to /etc/ld.so.conf.d/bacula.conf and ran ldconfig. I assume that the warning about plugins in /usr/local/lib can be ignored as a result? (Though, now that I look, I see the libs are indeed in /usr/local/lib, so perhaps I didn't need to make the extra file in ld.so.conf.d.)

Best,
Aaron

Re: Btape Test - Append Files Test

Jim Richardson

Be sure to factory default your tape drive.  I had the exact issue with my LTO7.  The drive was used in a non-linux environment before.  My steps to factory reset are a pain, but they got me working.  Yours may be different.  Manufacturer dependent.

 

# Steps

1. Install non-RAID HBA

2. install lin_tape & lin_taped

3. install ITDT

4. run full set of tests in ITDT

5. factory default settings - Specifically the "Read Past Filemark" setting MUST BE no

     http://www-01.ibm.com/support/docview.wss?uid=ssg1S7002972&aid=1

6. remove lin_tape & lin_taped

7. rmmod st

8. modprob st

9. power cycle library

10. Bacula configuration

11. btape test

Hi Kern,

Thanks for your help!

I removed the two lines you mentioned and had the same result.

The btape output is below. I'm running Debian 8.8 (kernel 3.16.0-4-amd64). I downloaded the Bacula 9.0.1 source from https://sourceforge.net/projects/bacula/files/bacula/9.0.1/ and compiled the binaries on my machine. The binaries are dynamically linked, so I added "/home/agreenblatt/software-bacula/bacula/src/stored/.libs" to /etc/ld.so.conf.d/bacula.conf and ran ldconfig. I assume that the warning about plugins in /usr/local/lib can be ignored as a result? (Though, now that I look, I see the libs are indeed in /usr/local/lib, so perhaps I didn't need to make the extra file in ld.so.conf.d.)

Best,

Aaron

End scanning the tape.
We should be in file 4. I am at file 5. This is NOT correct!!!!

The above Bacula scan should have output identical to what follows.
Please double check it ...

sample output, you MUST correct the problem
or Bacula will not be able to write multiple Jobs to
the tape.

Hello,

Please take out the:

Hardware End of File = no

and

Device Type = Tape

then try the test again.  If it fails please post the btape output, the OS you are running, the Bacula version, and where you got the binaries.

Best regards,

Hello,

I am attempting to use Bacula on a backup server and am having trouble with btape test in the append files section. I have read the documentation, searched on Google, and updated the firmware on my SAS card and tape drive. I don't see any particularly helpful log messages on the system. Any thoughts on where I should look to continue troubleshooting this? Could it have something to do with the SCSI driver in the OS?

Configuration is as follows: Debian 8 with Atto H1280 (also tried H644) SAS HBA and HP LTO6 tape drive. More details below.


Thank you.

Re: Btape Test - Append Files Test

Aaron Greenblatt
Hi Everyone,

Thanks for your help!

I looked around in HP's Library and Tape Tools software and couldn't find anything similar to a "Read Past Filemark" setting - the settings were limited to disabling the eject button and something else that didn't look very useful. I'm sure that HP has a this setting buried somewhere, but I'd expect that one has to call HP support to enable it.

Meanwhile, I installed Bacula 7.4.7 and the test passes in that version. I think the answer for now is to use version 7.4.7 to get my backup server running.

Is there any sort of information that would be useful for you from versions 9.0.0 or 9.0.1 (both gave me the same problem)?

Thanks,
Aaron

Hi Kern,

Thanks for your help!

I removed the two lines you mentioned and had the same result.

The btape output is below. I'm running Debian 8.8 (kernel 3.16.0-4-amd64). I downloaded the Bacula 9.0.1 source from https://sourceforge.net/projects/bacula/files/bacula/9.0.1/ and compiled the binaries on my machine. The binaries are dynamically linked, so I added "/home/agreenblatt/software-bacula/bacula/src/stored/.libs" to /etc/ld.so.conf.d/bacula.conf and ran ldconfig. I assume that the warning about plugins in /usr/local/lib can be ignored as a result? (Though, now that I look, I see the libs are indeed in /usr/local/lib, so perhaps I didn't need to make the extra file in ld.so.conf.d.)

Best,

Aaron

Hi Everyone,

Thanks for your help!

I looked around in HP's Library and Tape Tools software and couldn't find anything similar to a "Read Past Filemark" setting - the settings were limited to disabling the eject button and something else that didn't look very useful. I'm sure that HP has a this setting buried somewhere, but I'd expect that one has to call HP support to enable it.

Meanwhile, I installed Bacula 7.4.7 and the test passes in that version. I think the answer for now is to use version 7.4.7 to get my backup server running.

If Bacula 7.4.7 works, I suggest that you stick with it until I can test btape on 9.0.0. 


Is there any sort of information that would be useful for you from versions 9.0.0 or 9.0.1 (both gave me the same problem)?
Yes, I would appreciate it if you would open a ticket on this.  You can simply copy the contents of your emails into it -- the first email and this email.

Best regards,
Kern


Thanks,
Aaron

Hi Kern,

Thanks for your help!

I removed the two lines you mentioned and had the same result.

The btape output is below. I'm running Debian 8.8 (kernel 3.16.0-4-amd64). I downloaded the Bacula 9.0.1 source from https://sourceforge.net/projects/bacula/files/bacula/9.0.1/ and compiled the binaries on my machine. The binaries are dynamically linked, so I added "/home/agreenblatt/software-bacula/bacula/src/stored/.libs" to /etc/ld.so.conf.d/bacula.conf and ran ldconfig. I assume that the warning about plugins in /usr/local/lib can be ignored as a result? (Though, now that I look, I see the libs are indeed in /usr/local/lib, so perhaps I didn't need to make the extra file in ld.so.conf.d.)

Best,

Aaron

Hello,

Please take out the:

Hardware End of File = no

and

Device Type = Tape

then try the test again.  If it fails please post the btape output, the OS you are running, the Bacula version, and where you got the binaries.

Best regards,

Hello,

I am attempting to use Bacula on a backup server and am having trouble with btape test in the append files section. I have read the documentation, searched on Google, and updated the firmware on my SAS card and tape drive. I don't see any particularly helpful log messages on the system. Any thoughts on where I should look to continue troubleshooting this? Could it have something to do with the SCSI driver in the OS?

Configuration is as follows: Debian 8 with Atto H1280 (also tried H644) SAS HBA and HP LTO6 tape drive. More details below.
