Hi Bill
thank you for your as always helpful insights.
You are more than welcome, Thorsten. :)
I was not aware of the conflict between the libraries and baculas
autoclean feature. Immediately I turned the one of the lib off.
I test drove some time ago the alternate MTX script. It worked well
for some time but I ran in some kind of problem I do not remember.
Last but not least, the original script worked well after an update.
I believe it something to do with python on my system, which pretty
effectively was kind of broken (Suse Tumbleweed).
Funny, because the original `mtx-changer` combination bash & perl
script has not been touched by developers in many years. Not sure what
update you are thinking of. :)
What is the advantage of the alternate tapealert? From first
impression of your github I do not see any...
On https://github.com/waa/bacula-tapealert see the two secti
ons "THE PROBLEM", and "THE SOLUTION":
- Much better logging
- Automatic /dev/sg node detection (this is one of the most important
I think)
- Email an admin when TapeAlerts are reported
(and running it manually tries to log into an non-existing
directory, might be abetter idea to log in standard to /var/log
instead).
Good point. It was written on a system running Bacula Enterprise, and
of course, /opt/bacula/log is the default location for logs. But,
logging is disabled by default, and of course this is simply fixed by
using the `-f` option to specify the exact path and filename you would
like to log to. ;)
The mtx command gave the following reply:
mtx: Request Sense: Long Report=yes
mtx: Request Sense: Valid Residual=no
mtx: Request Sense: Error Code=70 (Current)
mtx: Request Sense: Sense Key=Illegal Request
mtx: Request Sense: FileMark=no
mtx: Request Sense: EOM=no
mtx: Request Sense: ILI=no
mtx: Request Sense: Additional Sense Code
= 20
mtx: Request Sense: Additional Sense Qualifier = 00
mtx: Request Sense: Field in Error = 00
mtx: Request Sense: BPV=no
mtx: Request Sense: Error in CDB=yes
mtx: Request Sense: SKSV=yes
mtx: Request Sense: Field Pointer = 00 00
READ ELEMENT STATUS Command Failed
So, what does this mean?
Your tape library is either broken, is not compatible with mtx (lol,
not likely), or you are pointing to the wrong device node (also not
likely).
Your library will never work with Bacula until and unless you are able
to get mtx status outputs from the command line, and can load/unload
tapes using mtx too.
Hi Bill,
coming back to bacula-tapealert: when I try to use it from command line
I get
/usr/libexec/bacula/bacula-tapealert.py:220: DeprecationWarning: 'count'
is passed as positional argument
st = re.sub('.*(/dev/)n(.*)', '\\1\\2', drive_device, re.S)
Independend if I use /dev/sg* or /dev/st0 /dev/nst0...
Not sure how to fix this
Cheers
