I also tried with different sizes and no difference.

Hi Josh,
the problem was again in the qemu rbd driver.
It was using int for several return values instead of int_64. I send 2nd
patch to the qemu list and ceph devel.
Could you please care that BOTH patches the one from yesterday AND today
get into qemu?
Greets,
Stefan

Hello
Now i can't find link where i read this info (this was old ceph wiki)
but there was written that rbd on osd can prevent hung. Does this
situation actual for present days?

Do you have other monitors in working order? The easiest way to handle
it if that's the case is just to remove this monitor from the cluster
and add it back in as a new monitor with a fresh store. If not we can
look into reconstructing it.

This is a description of the clock synchronization issue we are facing
in Hadoop:
Components of Hadoop use mtime as a versioning mechanism. Here is an
example where Client B tests the expected 'version' of a file created
by Client A:
Client A: create file, write data into file.
Client A:
I'm working on getting data structures for every rbd image request
initialized in one place, and similarly getting all osd object
requests for rbd images initialized at once at well. This series
addresses an issue I bumped into while trying to do this, and
then goes a little further to implement
Move the initialization of a read or write operation's offset,
length, and payload length fields into rbd_create_rw_op().
This will actually get removed in the next patch, but it finishes
the consolidation of setting these fields at osd op creation time.

Create a baseline function to encapsulate the creation of osd
requests, along with a matching function to destroy them. For now
this just duplicates what rbd_create_rw_op() does for read and write
operations, but the next patches will expand on this.
Since rbd_create_rw_op() is no longer used
Move the initialization of the CEPH_OSD_OP_CALL operation into
rbd_osd_req_op_create().

The two remaining osd ops used by rbd are CEPH_OSD_OP_WATCH and
CEPH_OSD_OP_NOTIFY_ACK. Move the setup of those operations into
rbd_osd_req_op_create(), and get rid of rbd_create_rw_op() and
rbd_destroy_op().

Both rbd_req_sync_op() and rbd_do_request() have a linger
parameter, which is the address of a pointer that should refer to
the osd request structure used to issue a request to an osd.
Only one case ever supplies a non-null linger argument: an
CEPH_OSD_OP_WATCH start. And in that one case it is
