replicate: optimistic changelog

2010-11-09T11:07:07+00:00

The standard way of maintaining changelog in replicate has been to
write out pending flags and to unset the pending flag post the
actual operation.

This new optimization kicks in only when all subvolumes are up.

The optimization is that, during pre-op, no changelog is written for
METADATA and ENTRY/RENAME operations. If during the operation nothing
failed, no changelog is updated in post-op either. If however,
something does fail during an operation, then, pending flags get
written during post op pointing only towards the failed nodes.

DATA transactions continue to work the way they are.

If one subvolume is down, pending flags are written in pre-op changelog
itself as before.

The impact of this optimization is only in the case when both servers
die or the client dies while the 'FOP' stage of the transaction is
in progress. By nature of METADATA and ENTRY operations, detecting a
mismatch later is not dependent on the presence of changelog. Changelog
only determines the direction in which self-heal happens for these types
of transactions. For the direction too this optimization does not have
a major impact because in the cases of failure (both servers dieing or
client dieing) the final state (direction of self-heal) would be
arbitrary anyways as the syscall wouldn't have completed.

- since quota is returned once the reply is recieved, 32 is too less value.
