Re: [Bacula-users] btape multivolume fill test fails on 7.4.4 but succeeds on 5.2.13

[Kern S. <ke...@si...>]

Hello,

Update:  The problem of the btape fill command not working has been 
around since about 2012.  I now have a fix for it, and can safely say 
that the problem resulted from some debug code that apparently only 
affected the btape fill command.  The debug code cleared some fields in 
the block after the block was written.

So, bottom line: the failure is a false alert.

I will push a patch to the Bacula repository this weekend and will 
consider releasing a version 7.4.5, since the fill command is important 
when doing a new installation.

Best regards,
Kern
