This file is full of 0s - it was created by
dd if=/dev/zero of=/solaris/d100/m1 bs=32k&
Then file system solaris/d100 was replicated in a similar way to zfs
send|zfs recv into solaris/d100-copy1.
Now I wonder how holes were created and why not as entire file...
Hmm, that's definitely curious. What do you mean by "a similar way to
zfs send | zfs recv"? Can you send me the full output of your 'zdb
-vvvv solaris/d100{-copy1} 809'?
