freebsd stable - Mar 2009 - dump | restore fails: unknown tape header type 1853384566

Hello!

I'm trying to migrate a filesystem from one disk to another using:

    dump a0hCf 0 32 - /old | restore -rf -

(/old is already mounted read-only). The process runs for a while and 
then stops with:

    [...]
      DUMP: 22.85% done, finished in 3:57 at Tue Mar 24 01:03:21 2009
      DUMP: 24.66% done, finished in 3:50 at Tue Mar 24 01:00:58 2009
      DUMP: 26.44% done, finished in 3:43 at Tue Mar 24 00:59:14 2009
    unknown tape header type 1853384566
    abort? [yn]

Any idea, what's going on? Why can't FreeBSD's restore read
FreeBSD's
dump's output?

The system runs 7.0-STABLE from July 6th, i386. I just tried updating 
the dump and restore from source (latest 7.x) -- the error is the same...

Please, advise. Thanks!

What happens if you don't use the cache?
Also, do you really want -h 0? That means you skip nodump marked files at a 
level 0 dump.

No big difference:

    dump a0f  - /old | restore -rf -
    [...]
      DUMP: 17.25% done, finished in 3:27 at Tue Mar 24 05:42:00 2009
      DUMP: 20.36% done, finished in 3:09 at Tue Mar 24 05:28:13 2009
      DUMP: 23.83% done, finished in 2:50 at Tue Mar 24 05:14:32 2009
    unknown tape header type -621260722
    abort? [yn]

Looks like a junk value somewhere... Unitialized variable or some such.

I think before this goes any further, you will need to try
rebooting/unmouting it, running fsck on it, and then dump the unmounted
partition and see how that goes.

Is your /tmp large enough to restore?

Try
dump -a0 -h 0 -C 32 -f - /old
instead.
Your command line should work, but I've had trouble with similar ones 
and have been able to solve it by separating the options.
