Folks,
Today i found ceph -s is really slow and just hanging for minute or 2
minute to give me output also same with "ceph osd tree" output,
command just hanging long time to give me output..
This is what i am seeing output, one OSD down not sure why its down
and what is the relation with command running slow?
I am also seeing what does that means? " 369 slow requests are blocked
> 32 sec. Implicated osds 0,2,3,4,5,6,7,8,9,11"
