Bill Sommerfield,
Because, first, I have seen alot of I/O
occur while a snapshot is being aged out
of a system.
I don't think that during the resilvering process
accesses (read, writes) are completely
stopped to the orig_dev.
I expect at least some meta reads are
going on.
With some normal sporadic read failure, accessing
the whole spool may force repeated reads for
the replace.
So, I was thinking that a read access
that could ALSO be updating the znode. This newer
time/date stamp is causing alot of writes.
Depending on how the fs meta and blocks are
being accessed, the orig_dev may also
have some normal writes until it is offlined.
