I was wondering if I could get some help reviewing the results of the
btape test output. I think that it failed but I am not 100% sure, my
reading of the manual didn't show me what to expect to see for the
results.
http://bacula.org/manuals/en/utility/utility/Volume_Utility_Tools.html#TapeTestingChapter
Any feedback including pointers as to a different place in the doc to
read will be appreciated.
Thanks -Jason

I'm going to write 1000 records and an EOF
then write 1000 records and an EOF, then rewind,
and re-read the data to verify that it is correct.
This is an *essential* feature ...

This command simulates Bacula writing to a tape.
It requires either one or two blank tapes, which it
will label and write.
If you have an autochanger configured, it will use
the tapes that are in slots 1 and 2, otherwise, you will
be prompted to insert the tapes when necessary.
It will print a status approximately
every 322 MB, and write an EOF every 3.2 GB. If you have
selected the simple test option, after writing the first tape
it will rewind it and re-read the last block written.
If you have selected the multiple tape test, when the first tape
fills, it will ask for a second, and after writing a few more
blocks, it will stop. Then it will begin re-reading the
two tapes.
This may take a long time -- hours! ...
Do you want to run the simplified test (s) with one tape
or the complete multiple tape (m) test: (s/m) s
Simple test (single tape) selected.
