Hi all,
When i stop the respawning osd on an OSD node, another osd is respawning
on the same node. when the OSD is started to respawing, it puts the
following info in the osd log.
slow request 31.129671 seconds old, received at 2015-02-13 19:09:32.180496:
osd_op(*osd.551*.95229:11 191
It's not entirely clear, but it looks like all the ops are just your
caching pool OSDs trying to promote objects, and your backing pool OSD's
aren't fast enough to satisfy all the IO demanded of them. You may be
overloading the system.
