Hi Irek,
Hi,
I have a problem with timestamps of objects created in Rados Gateway.
Timestamps are supposed to be in UTC timezone but instead I have strange
offset shift.
Server with Rados Gateway use MSK timezone (GMT +3). NTP is set, up and
running correctly. Rados Gateway and Ceph has no objects (usage
librbd caches data at a buffer / block level. In a simplified example, if you
are reading and writing random 4K blocks, the librbd cache would store only
those individual 4K blocks. Behind the scenes, it is possible for adjacent
block buffers to be merged together within the librbd cache.

Ceph operates under the hood now.

machines off and forget about them for a while. It's no great loss; I just

maybe it is that kernel bug you mentioned. Although its not an exact

That seems related to http://tracker.ceph.com/issues/10536 which seems to be
resolved. Could you create a new issue with a link to 10536 ? More logs and

I would be inclined to shut down both OSDs in a node, let the cluster

Repeat until all the OSDs are taken out of the cluster. Then I would
