Chris is right. Here's a little more of what's going on behind the
scenes:
* When amdump (taper) completes, it leaves the tape where it left off
(at the end). In theory you could use this to tack on some non-Amanda
dump information to the tape, although that can be tricky.
* Amidxtaped (called by amrecover) does **not** do any tape positioning
before trying to read the image. This is so you can do the motion
yourself on devices that fsf much faster than read/scan.
The combination of these first two items probably gave you your
initial error.
* Amidxtaped *does* rewind the tape when it completes (even if there
was an error), the theory being that if you need to do another restore
from the same tape it will be in a known position to start from.
This is probably why it worked the second time for you.
Personally, I run a wrapper shell script around amdump and one of the
things it does is unload any tape amdump writes to. So whenever I'm
doing a restore, I have to mount the requested tape and therefor it's
at a known position.
I also always position the tape myself to do a restore (rewind followed
by an appropriate fsf) because it's much faster on the types of drives
I have.
