Hi,

I have a few score trees in Venti that p9p's venti/copy wouldn't copy,
but p9's would. venti/copy aborted with:
copy: reading block 0000000000000000000000000000000000000000 (type
16): read asked for 0000000000000000000000000000000000000000 got
da39a3ee5e6b4b0d3255bfef95601890afd80709

P9's venti/copy has a test, in its walk() function, as to whether a
score is all-zeros. P9P's venti/copy doesn't. Adding this test allows
my copy to proceed.

Is there any reason p9's venti/copy has this test? It seems like a
dubious one, since the all-zero score shouldn't ever be in Venti. But
it's also necessary to copy these trees...

Thanks,
-- vs

thanks for the tip. i got the same error (even the score, i think)
when i tried copying some vbackup scores to a new server a few weeks
ago. i hadn't thought of trying a different copy until you brought it
up. using plan 9's copy instead of p9p's seems to be working well
enough so far
