I built stable/9.

Sorry, the revision I mention is wrong because I have one checkout of
/base/ (with head/ and stable/9 inside). I always run svn update from
this directory, so when I do "svn info" in stable/9, it indicates the
last revision for the entire checkout, which as in head as you pointed
out.

I checked with "svn log" and the last revision is 226115. Sorry for
the mistake.

Yes, it's pretty full right now (> 95%).

Yes, as described in the RootOnZFS guide.

Now, I have zfsboot and zfsloader from 9.0-BETA3's DVD1. The problem
is the same with the one from r226115.

I thought those patches had been committed but it seems they haven't been.

I tried this patch but it doesn't fix the problem.

Andriy suggested me to try tools/tools/zfsboottest and this tool reads
the files properly.

Peter, I'll try to send/recv as soon as I have access to a storage
with enough space.

Thank you for your help!
