[Dump-users] Re: st driver's buffer corrupting multivolume dumps

[Brent B. <br...@ke...>]

Since some of you said to write back if I found a solution...

After much searching, I did finally find the way to make multivolume 
archives reliable instead of corrupting at the end-of-tape points.  It 
was back in the archives of this list, but was only mentioned there once 
and never again, so...

mt stclearoptions async-writes buffer-writes

I did this, and a 'restore -C' verified good across a 4-volume set of 
tapes.  It makes me wonder if this problem is actually the reason that 
Amanda can't span tapes -- perhaps the developers never did get around 
this issue with the st tape driver, and gave up.  (Officially, the word 
on Amanda is that you can't -- is this the only thing stopping them?)
