protocol/client: Periodically attempt reopens

2013-02-03T19:33:31+00:00

If the brick is taken down and the hard disk is replaced
and the brick is brought back up, the re-opens of the open-fds
will fail because the file is not present on the brick.
Re-opens are not attempted even if the files are re-created by
self-heal until the brick is brought down after the files are
re-created and brought back up. This is a problem with a VM-store
in a replica-setup.  Until the fd is re-opened the writes will
never happen on the brick where the hard-disk is replaced.
To handle this situation gracefully, client xlator is enhanced
to perform finodelk, fxattrop, writev, readv using anonymous fds
if the file is yet to be re-opened. If the fop succeeds then client
xlator attempts re-open.

fd: filter anonymous FD from fd_lookup() result

2013-01-29T00:44:51+00:00

Those callers whose requirements can accommodate an anonymous FD
need to call fd_anonymous(). fd_lookup() is strictly for open()ed
file descriptors only.

debug/trace: save the recent fops received in the event-history

2013-01-18T05:15:13+00:00

* Make use of event-history in debug/trace xlator to dump the recent fops,
when statedump is given. trace xlator saves the fop it received along
with the time in the event-history and upon statedump signal, dumps its
history. The size of the event-history can be given as a xlator option.

* Make changes in trace to take logging into log-file or logging to
history as an option. By default both are off.
