Now you can create diagrams easily with the ".. ditaa::"
directive in the Sphinx documents.
admin/build-doc now checks for debs required for building
the documentation, or just lists commands missing for hosts
not using dpkg.

If a secret is specified, store and use it, but otherwise
check for a pre-existing secret to use.

add_key will return -1 when an error occurs, which should be handled at a higher level and not printed here.

Pass in fs_op_seq (last_committed_seq), not the next expected seq, so we
can avoid subtracting and adding 1 in odd places.

It is perfectly fine to read events that are older than the fs's seq from
the journal; open() will skip them when positioning the read pointer on
open.
Also, this code is nonsensical; it always failed the assertion.

last_committed_seq is the last seq committed to the fs, not the journal.
Set it when we begin replay with the fs provided value, not from the newest
entry in the journal.

The 'mon' perfcounter is for the local daemon and is always registered.
The 'cluster' perfcounter is for cluster state, and is only registered
(and thus only shows up via the admin socket) when the current daemon is
part of the cluster quorum.
No actual counters yet.

This could conceivably cause the reply ordering mismatch seen in bug
#1490. Not sure why we didn't also fix this caller when we fixed that
bug last time :).

This might happen if, e.g., the file_layout specifies an osd that later
is removed from the cluster entirely. Just ignore it instead of making
upper layers duplicate this check.

This reverts commit 6fbab6da69.
This fails a unit test.
And I change my mind.. I think this is most cleanly handled inside crush, so
we don't duplicate the same check that is generating the error with an different
data structure.
It was not an index, and seems to contain recommendations
for system configuration. I have renamed it to confusing.txt
and will merge it in a future commit.

which was a copy of PlanningImplementation.txt

restored previous index.rst, which was overwritten with a copy
of PlanninImplementation.txt, but removed all of the recursively
included content from the document.
I will cherry-pick merge the new contents in a subsequent commit.
