Yes. After the time-out of 600 secs the OSDs got marked down, all PGs got 
remapped and recovery/rebalancing started as usual. In the past, I did service 
on servers with the flag noout set and would expect that 
mon_osd_down_out_subtree_limit=host has the same effect when shutting down an 
entire host. Unfortunately, in my case these two settings behave differently.

If I understand the documentation correctly, the OSDs should not get marked out 
automatically.

Did it start rebalancing?
