Got this fixed. This is because of the following assertion in the function
'eval_repop' of the base tier code.
assert(entity_name_t::TYPE_OSD != m->get_connection()->peer_type);
When moving to proxy write, this assertion doesn't hold any more. After
removing it, the problem is fixed now.

In the 2nd scenario, what if the write by client B fails for some reason? Do we
also fail the following read by A or B? Or return the read with the client A
write content? If we return the read with client A write content, client A
still needs to communicate with B to know which version of the c

The ordering scenario is that with client a and b, assuming a and b are
messaging between them, then a read posted by client b after client a has
successfully written will always read the client a content. Similarly, an
ordered write b
What I understand is that if the read op specifies the RWORDERED flag, it is
processed in order. Otherwise, it may be out of order.

For multiple clients accessing the same volume, same object, I guess the
clients need to do some synchronization between them to guarantee what it reads
is what it wrote. That is to say, if two clients, say A and B, A is doing
write, B is doing read. If B wants to read what A writes, it needs to

Folks
I'm wondering if this is related to the question I posed a few days ago..
Can CEPH support 2 clients simultaneously accessing a single volume - for
example a database cluster - and honor read and write order of blocks across
the multiple clients?
Can you comment?

You can run them all by executing "make check [-j N]". The executables
run as part of that are specified in the makefiles throughout the

Suggestion:
radosgw should handle injectargs like other ceph clients do?
This is not a major annoyance, but it would be nice to have.

Hi, all
Is any guideline that describes how to run the ceph unit test, and its
basic architecture?

Hi Yehuda,
I just wanted to ping this issue since it seems to have been forgotten (and is
still present in all versions of rest-bench I tried). The tracker issue was
marked as resolved, but the fix is only (AFAICT) in wip-3896 and there isn’t a
pull req to bring it to master or any release branc
