Re: [9fans] Fs64 file server, partition boundaries out of range

i'd really be suprised if you had actually used up 50G.  i think that
the problem is that copyworm trys to copy the whole worm --- even
empty blocks.

the relevant check in getbuf combined with written size seems to do
this:

	static Devsize
	writtensize()
	{
		Devsize lim;

		for(lim = devsize(worm); lim > 0; lim--)
			if(blocknum(lim) is "active" OR blocknum(lim) can be read)
				return lim+1;
		return 0;
	}

am i missing something?  it's not obvious to me how to determine the last
block that's actually got data in it.
