Backup Central

Hi,

I've got the following error when I run amrecover:

---------
amrecover> add dumpdates
Added /etc/dumpdates
amrecover> extract

Extracting files using tape drive 0 on host typha.nmsu.edu.
The following tapes are needed: Biology-1

Restoring files into directory /home/cngo
Continue [?/Y/n]? y

Extracting files using tape drive 0 on host typha.nmsu.edu.
Load tape Biology-1 now
Continue [?/Y/n/s/t]? y
EOF, check amidxtaped.<timestamp>.debug file on typha.nmsu.edu.
amrecover: short block 0 bytes
UNKNOWN file
amrecover: Can't read file header
extract_list - child returned non-zero status: 1
Continue [?/Y/n/r]? y
amrecover>
------------

That error disappears if I comment out the 'tapedev "0" 'in my amanda.conf file

-----amanda.conf--
tpchanger "chg-scsi" # the tape-changer glue script
tapedev "0"
changerfile "/usr/pkg/etc/amanda/backup/chg-scsi.conf"
-------

However if I do that, amcheck generates the following error:

-----------
% amcheck backup
Amanda Tape Server Host Check
-----------------------------
Holding disk /data/amanda: 24318770 KB disk space available, that's plenty
amcheck-server: could not get changer info: check your config and use a config
file for chg-scsi

Amanda Backup Client Hosts Check
--------------------------------
Client check: 1 host checked in 0.060 seconds, 0 problems found

(brought to you by Amanda 2.4.4p2)
---------------

if I change 'tapedev "0" ' to 'tapedev "enrst0"' for example, amrecover works
well but amcheck still gives that error message. As I understand from amanda
documents, the value of tapedev is the configuration to use, so it should be a
number between 0 and 9.

I don't think it's good idea to set 'tapedev "0"' when running amdump and
comment it out when running amrecover. I would appreciate it very much if
anyone could advise me how to resolve that problem.

Thank you very much,

Co

What are the contents of amidxtaped.<timestamp>.debug?
That'd probably be most enlightening.

As a guess, I'd say that the tape `Biology-1' wasn't
loaded when amidxtaped went to try and read from it. Did you
see (hear?) the robot load the tape at the after you answered
yes, and before the above error message occurred.

The error disappears, but are you able to restore the
file?

There are several debug and diagnostics files at "/tmp/amanda". They follow
that convention. Do you told to amanda to backup the /tmp directory (or /
filesystem) ? Or maybe your /tmp is full, preveting the creation of the
file...

Hi,

I'm sure the tape was loaded because I checked it by running amtape and the
files are restored when I comment out the tapedev "0". Please have a look at
the amidxtaped* file attached. It seems that parameter for the tape device argv
[7]="0" is not what amrecover wants.
Thank you very much,

Co
