Summary: if the "tapelist" file doesn't exist, amlabel creates the file
but doesn't populate it. (Again, this is using Amanda 3.4.3.)
(In the following examples, I delete the 00000.TESTBACKUP-01 file out of
the vtape slot1 directory before each test run, so the only difference
is the existence of the "tapelist" file.)
First test: if tapelist doesn't exist beforehand, amlabel creates it,
but the line for the newly-labled tape isn't written to it:
=====
# rm tapelist
# cat tapelist
cat: tapelist: No such file or directory
# su backup -c "amlabel TestBackup TESTBACKUP-01 slot 1"
Reading label...
Found an empty tape.
Writing label 'TESTBACKUP-01'...
Checking label...
Success!
# cat tapelist
# ls -l tapelist
-rw------- 1 backup backup 0 Mar 15 17:58 tapelist
=====
(The label is in fact written to the vtape, so the end result a labeled
vtape that isn't listed in the tapelist file, as shown if I repeat the
label command again immediately after the previous run:
=====
# su backup -c "amlabel TestBackup TESTBACKUP-01 slot 1"
Reading label...
Found label 'TESTBACKUP-01' but it is not in the tapelist file.
Not writing label.
Not writing label.
=====
)
However, if I create an empty tapelist file first, the tape-line is
written to the file as expected:
=====
# rm tapelist
# cat tapelist
cat: tapelist: No such file or directory
# touch tapelist
# su backup -c "amlabel TestBackup TESTBACKUP-01 slot 1"
Reading label...
Found an empty tape.
Writing label 'TESTBACKUP-01'...
Checking label...
Success!
# cat tapelist
0 TESTBACKUP-01 reuse BLOCKSIZE:32 POOL:TestBackup STORAGE:TestBackup
CONFIG:TestBackup
=====
At first glance, the amlabel.20170315*.debug files for the two runs
appear identical (e.g. both are 33 lines and 449 words long, according
to "wc"), so I don't believe the log gives any indication that something
went wrong.
(Jean-Louis,) let me know if the cause of this problem is immediately
obvious to you or if it would help for me to do some debugging the
Tapelist.pm code.
Thanks.
