problem with amcheckdump

[marozsas]

I have two samba DLE in my disklist. They are:

bigslam         win2k_backup	//srv004/Backup   root-tar
bigslam         win2k_wwwroot	//srv004/wwwroot  root-tar

not only amcheckdump is returning an error on this DLE (please, check [url]http://forums.zmanda.com/showthread.php?t=1539[/url]) , but EVERY DLE in the tape after these return a error too !

        ...
        [-P|--machine-pass] service <password>
Error writing fd 4: Broken pipe
Error reading device or writing data to validation command.
Validating image bigslam:root datestamp 20081202005402 level 0 part 1 on tape diario-24 file #7
Validation process returned 1 (full status 256)
  using '/bin/tar tf - > /dev/null && cat > /dev/null'.

or this

       ...
        [-A|--authentication-file FILE] [-S|--signing on|off|required]
        [-P|--machine-pass] service <password>
Error writing fd 4: Broken pipe
Error reading device or writing data to validation command.
Validating image minibit:fileserver_p-t datestamp 20081202005402 level 1 part 1 on tape diario-24 file #39
Validation process returned 1 (full status 256)
  using '    /usr/bin/gzip -dc |/bin/tar tf - > /dev/null && cat > /dev/null'.

I guess the error status was not reset or something like that.

What release are you using?
In amanda-2.6.0p2, it should correctly check the following images after an error.
amanda-2.6.0p2 can't check samba image, it will be fixed in 2.6.1

Hi martineau, it is amanda-backup_server-2.6.0p2-1.suse10.

In amanda-2.6.0p2, it should correctly check the following images after an error.

Looks like there is a bug somewhere....
Every day there is a different backup image after the 2 samba images.
And, in a consistent way, every regular (not samba) image following the samba image is marked as "Validation process returned 1 (full status 256)".
I double check this and I restore every image flagged in this way just to check if there is any problems. Every restore was successful, so I am sure there is no problem with the image itself on the tape.
One day, just for fun, I commented the samba DLE in disk list, so the samba backup was not made. The amdumpcheck didn't returned an error in this day.

amanda-2.6.0p2 can't check samba image, it will be fixed in 2.6.1

Good to know. As soon it will be released I will upgrade.

thanks,

This error come from the samba share error, it's just a misalignment of the error and is not easy to fix.

The attached patch fix the samba error, you can apply it to the amcheckdump perl script.

SOLVED !

Thanks Martineau ! It worked !

In fact I had to change the patch to

...
"SMBCLIENT" => "/bin/tar tf -"
...

because the symbol @GNUTAR@ is not defined anywhere in the rpm package 2.6.0p2.

I'm glad it is working now, amcheckdump is verifying the samba images as expected:

Validating image bigslam:win2k_wwwroot datestamp 20081205005401 level 1 part 1 on tape diario-27 file #43
  using '/bin/tar tf - > /dev/null && cat > /dev/null'.
Validating image bigslam:srv datestamp 20081205005401 level 1 part 1 on tape diario-27 file #44
  using '/bin/tar tf - > /dev/null && cat > /dev/null'.
Validating image bigslam:win2k_backup datestamp 20081205005401 level 1 part 1 on tape diario-27 file #45
  using '/bin/tar tf - > /dev/null && cat > /dev/null'.
Validating image bigslam:firebird datestamp 20081205005401 level 1 part 1 on tape diario-27 file #46

I was studying the code and I see why it is difficult to fix. I will try to fix it and if I can, I will return a patch to you to decide if it good enough to go to the main code.

thanks again !

cheers,
