Is write(2) made durable atomically?
Will a write(2) to a ZFS file be made durable atomically?
Under the hood in ZFS, writes are committed using either shadow paging or
logging, as I understand it. So I believe that I mean to ask whether a
write(2), pushed to ZPL, and pushed on down the stack, can be split into
multiple transactions? Or, instead, is it guaranteed to be committed in a
single transaction, and so committed atomically?
